Understanding the differences between species is crucial, as each requires distinct management approaches. Misidentification can lead to ineffective treatment , wasted resources, and prolonged infestations, particularly with challenging species such as Pharaoh’s ants . PGM remains committed to promoting professional standards in integrated pest management and encouraging evidence-based approaches to ant control . We strongly advocate for the involvement of qualified pest control professionals, particularly when dealing with persistent infestations or species of public health concern. Introduction Ants are among the most successful insects on Earth , with over 60 species recorded in the United Kingdom. Whilst the vast majority of these species live harmoniously within our ecosystems, contributing to soil aeration, seed dispersal, and natural pest control , a handful have adapted to exploit human environments. When ants enter our homes, contaminate food supplies, or establish colonies within commercial premises , they transition from beneficial insects to significant pests. Current accepted figure Britain hosts approximately 51 native ant species , with additional introduced species bringing the total to around 60+ recorded species. 61 native and established species are generally recognised in modern UK checklists. Up to 65 species if including : rare accidental introductions historic records species confined to heated buildings (e.g. tropical ants) The UK has relatively low ant diversity compared with southern Europe because of the cooler climate. Most UK species belong to a few dominant genera: Lasius (garden ants) Myrmica (red ants) Formica (wood ants) Temnothorax (small cavity nesters) Breakdown by status chart  This reflects current BWARS-supported understanding as of March 2026. Category Approx. number Native outdoor species 55 Rare/scarce natives 6 Introduced indoor species 3–5 Total recorded 61–65 The importance of accurate identification cannot be overstated . Different ant species exhibit vastly different behaviours, nesting preferences, and colony structures. A treatment approach that successfully eliminates Black Garden Ants may prove entirely ineffective against Pharaoh’s Ants, potentially causing colony fragmentation and worsening the infestation. Similarly, the discovery of protected wood ant species on a development site requires careful consideration of conservation obligations rather than control measures. Ant Species Commonly Encountered in UK Homes and Buildings Chart Common name Scientific (Latin) name Notes Black Garden Ant Lasius Niger Most common UK household ant Red Ant Myrmica Rubra Often confused with wood ants Yellow Meadow Ant Lasius Flavus Mostly lives underground Roger’s Ant Hypoponera Punctatissima Indoor species, often in warm buildings Pharaoh’s Ant Monomorium Pharaonis Persistent indoor pest species Ghost Ant Tapinoma Melanocephalum Rare in UK outdoors; occurs in heated buildings Wood Ant Formica Rufa Species Group Includes Formica rufa, Formica polyctena, Formica aquilonia Carpenter Ant Camponotus Herculeanus (UK native) Mostly found in Scotland’s forests For homeo wners , early identification enables informed decisions about whether DIY methods might suffice or whether professional assistance is necessary. For businesses , particularly those in the food industry or healthcare sector, rapid and accurate identification is essential for maintaining hygiene standards, protecting brand reputation, and ensuring regulatory compliance. For pest control professionals , precise identification underpins the selection of appropriate control strategies and helps set realistic client expectations regarding treatment timescales and outcomes. This guide focuses on the species most commonly encountered in pest control contexts, alongside those of particular concern due to their behaviour, distribution, or impact. Understanding these speci es will enable readers to make informed decisions about ant management and recognise when professional expertise is required . Understanding Ant Biology and Behaviour Before examining individual species, it is helpful to understand the fundamental biology and behaviour that all ants share. Ants are social insects belonging to the family Formicidae, living in organised colonies that can range from a few dozen individuals to hundreds of thousands. Colony Structure Ant colonies operate as superorganisms , with distinct castes performing specialised roles. The queen is the reproductive centre of the colony, capable of living for many years and producing thousands of eggs . In some species, colonies may contain multiple queens, significantly increasing their reproductive potential and resilience. Worker ants, which are sterile females, perform all colony maintenance tasks including foraging, brood care, nest construction, and defence. Male ants exist primarily for reproduction , developing from unfertilised eggs and typically appearing only during the reproductive season. Life Cycle and Seasonal Patterns Ants undergo complete metamorphosis, progressing through egg, larval, pupal, and adult stages. The duration of this development varies by species and environmental conditions, typically taking several weeks to months. In the UK, most ant species exhibit pronounced seasonal activity patterns. Colony activity increases in spring as temperatures rise , peaks during summer months, and declines in autumn as ants prepare for winter dormancy. A circular diagram showing the four-stage lifecycle of the Black Garden Ant (Lasius niger) egg, larva, pupa, and adult. The most visible manifestation of ant reproductive activity is the emergence of flying ants, often referred to as “ flying ant day ,” though this is somewhat of a misnomer. Whilst there is often a peak period in July or August when weather conditions are optimal, flying ants may appear over several weeks . These winged individuals are reproductive males and virgin queens embarking on nuptial flights. After mating, males die, and fertilised queens shed their wings to establish new colonies. Foraging Behaviour and Food Preferences Ants are remarkably adaptable in their dietary habits. Many species exhibit a preference for sweet substances, feeding on honeydew produced by aphids or seeking out sugary foods in human environments . Others are predatory or scavengers, feeding on proteins from dead insects or food waste. Some species, such as Black Garden Ants, adjust their dietary preferences seasonally, favouring proteins during brood-rearing periods and carbohydrates at other times. Foraging ants lay chemical trails using pheromones, enabling other workers to locate food sources efficiently . These trails explain why ants often appear in large numbers, following the same route to and from a food source. The trails can persist for extended periods, continuing to attract ants even after the original food source has been removed. Nesting Habits UK ant species demonstrate diverse nesting preferences. Many native species nest outdoors in soil, creating networks of tunnels and chambers beneath the surface. Others nest in rotting wood, under stones, within cavity walls, or in the fabric of buildings. Some species, parti cularly introduced tropical species like Pharaoh’s Ants, are obligate indoor nesters in the UK, requiring the constant warmth of heated buildings to survive. Understanding these fundamental aspects of ant biology provides essential context for the species profiles that follow, helping to explain why different ants behave as they do and why management approaches must be tailored accordingly. Most Common UK Ant Species Black Garden Ant (Lasius Niger) At a glance  Black Garden Ant Latin name : Lasius niger Size : Workers 3–5 mm; queens up to 9 mm Colour : Glossy black; some workers slightly dark brown Key features : Smooth, rounded thorax; elbowed antennae; nests in soil or under stones Habitat/Notes : Very common in gardens and urban areas; forms large colonies The Black Garden Ant is by far the most commonly encountered ant species in the UK , responsible for the overwhelming majority of ant-related enquiries to pest control companies. This species is native to the UK and has adapted remarkably well to human environments whilst maintaining significant populations in natural habitats. Physical Identification Characteristics Workers measure 4-5mm in length and are dark brown to black in colour, with a slightly lighter brown coloration on the legs and antennae. The body has a smooth, shiny appearance with sparse, short hairs. Common Black Garden Ant - Scientific Name (Lasius Niger) Notes: Most common UK household ant. Queens are significantly larger at 15mm and are similarly coloured. When viewed under magnification, Black Garden Ants have a single, small, rounded bump (petiole) between the thorax and abdomen, and they lack a sting, though they can bite if handled roughly . Distribution and Habitat Preferences This species is found throughout the UK in virtually every habitat type, from urban centres to rural farmland. They are supremely adaptable and opportunistic in their nesting site selection . Outdoors, they typically nest in soil , often beneath paving slabs , stones , or at the edges of lawns where the soil is warmer and drier . They may also nest in rotting wood , compost heaps , or within the roots of plants . Indoors, they may establish satellite nests in cavity walls , beneath flooring, or in other sheltered locations, though the main colony typically remains outside . Nesting Behaviour and Colony Size Black Garden Ant colonies are typically monogynous (containing a single queen) and can grow to contain 5,000-15,000 workers , though larger colonies have been recorded. The queen can live for up to 30 years under optimal conditions, making these some of the longest-lived insects in the UK. Colonies mature slowly, typically taking 4-5 years before producing flying ants. Once mature, colonies produce flying ants annually, usually during warm, humid weather in July and August, contributing to the phenomenon of “flying ant day.” When They Become a Pest Concern Black Garden Ants become problematic when they enter buildings in search of food. They are particularly attracted to sweet substances but will also feed on proteins. Foraging workers follow chemical trails, often appearing in large numbers once a food source is located . Whilst they do not pose direct health risks and do not transmit diseases, they can contaminate food preparation areas and stored foods. Their presence can be distressing to householders and damaging to business reputations, particularly in the hospitality and retail sectors. Garden infestations can also cause concern when ants farm aphids on ornamental plants or food crops, protecting them from predators to harvest their honeydew. This relationship can lead to increased aphid populations and associated plant damage. Management Considerations For minor incursions, thorough cleaning to remove food sources and disrupt pheromone trails may suffice. However, established colonies require more comprehensive approaches. Surface sprays have limited effectiveness as they do not reach the colony. Gel baits containing slow-acting insecticides allow foraging workers to transport the toxin back to the nest, achieving colony elimination. External treatments around building perimeters can create barriers to foraging ants. Professional pest controllers can identify entry points, locate nest sites, and implement targeted treatments that provide long-term control rather than temporary relief. PGM Pest Control recommends professional involvement for persistent or recurrent infestations . Red Ant (Myrmica Rubra) At a glance  Red Ant Latin name : Myrmica rubra Size : Workers 4–5 mm Colour : Reddish-brown body, darker abdomen Key features : Distinct nodes (petiole and postpetiole) between thorax and abdomen; stinger visible Habitat/Notes : Often found in lawns and damp meadows; can bite if disturbed Red Ants, also known as European Fire Ants , are significantly more aggressive than Black Garden Ants and possess a painful sting, making them a more serious concern when encountered in residential gardens, community parks, or recreational areas. Identification Features and Distinguishing from Other Species Workers measure 4-5mm in length, similar in size to Black Garden Ants, but are reddish-brown in colour rather than black. The body has a more matt appearance with noticeable body hairs. Common Red Ant - Scientific Name (Myrmica Rubra) Notes: Often confused with wood ants. Queens measure 6-7mm, making them less dramatically larger than workers compared to other species. A key distinguishing feature is the presence of two small bumps (petiole nodes) between the thorax and abdomen, visible under close examination. Unlike Black Garden Ants, Red Ants possess a functional sting. Habitat and Nesting Sites Red Ants prefer damper conditions than Black Garden Ants and are commonly found in grassland, woodland edges, gardens, and parks. They nest in soil, often in lawns, beneath logs, or under stones. Their nests are less conspicuous than those of some other species, with minimal surface disturbance. In gardens, they may nest in rockeries, raised beds, or beneath garden features. Stinging Behaviour and Public Health Implications When their nest is disturbed, Red Ants respond aggressively, with multiple workers delivering painful stings . The sting produces a burning sensation and can result in localised swelling, redness, and itching that may persist for several days. For most people, these stings are painful but not dangerous. I ndividuals with allergies may experience more severe reactions requiring medical attention The aggressive nature of Red Ants makes them particularly problematic in areas used by children, such as school playing fields, parks, and residential gardens. Nests in lawns can make gardening or recreational activities unpleasant or impossible. Control Challenges and Professional Approaches Red Ant colonies can be polygynous, containing multiple queens, which makes them more resilient to control efforts and capable of rapid recovery if treatment is incomplete. Colony sizes typically range from a few hundred to several thousand workers. Control requires locating all nest sites , which can be challenging as colonies may occupy multiple interconnected nests. Insecticidal dusts applied directly to nests can be effective, as can baiting programmes using protein-based baits . Surface sprays are generally ineffective and may cause colony fragmentation, worsening the problem. Due to the painful stings and the complexity of ensuring complete colony elimination, professional pest control is strongly recommended for Red Ant infestations , particularly in public spaces or areas frequented by vulnerable individuals. Yellow Meadow Ant (Lasius flavus) At a glance  Yellow Meadow Ant Latin name : Lasius flavus Size : Workers 2–3 mm Colour : Yellowish to light golden brown Key features : Small, smooth-bodied; very little pigmentation; antennae elbowed Habitat/Notes : Usually nests underground in grassy areas, rarely forages above ground The Yellow Meadow Ant is a fascinating species that rarely comes into conflict with humans due to its subterranean lifestyle , though its presence is often indicated by the characteristic mounds it creates in grassland. Physical Description and Identification Workers are small, measuring 2-4mm in length, and are pale yellow to yellowish-brown in colour. Queens are larger at approximately 7-9mm and are similarly coloured. Yellow Meadow Ant - Scientific Name ( Lasius Flavus) Notes: Mostly lives underground The entire body is covered in fine, short hairs, giving it a slightly furry appearance. Due to their subterranean lifestyle, Yellow Meadow Ants are rarely seen above ground , and identification typically occurs when nests are excavated. Subterranean Lifestyle and Soil Mounds Yellow Meadow Ants live almost entirely underground, constructing extensive tunnel systems in the soil. They rarely venture to the surface, instead feeding on the honeydew produced by root aphids, which they tend in their underground chambers. This mutualistic relationship provides the ants with a reliable food source without the need for surface foraging. The most visible evidence of Yellow Meadow Ant colonies is the distinctive mounds of excavated soil they create, which can reach 40cm in height and 1m in diameter in undisturbed grassland. These mounds develop over many years as the colony grows and can persist for decades. In well-maintained lawns, mounds are typically smaller and may be regularly mown, making them less obvious. Limited Pest Status Yellow Meadow Ants rarely become pests as they have minimal interaction with human activities . Occasionally, their mounds may be considered unsightly in formal lawns or may interfere with sports fields and golf courses. Very rarely , if nests are disturbed during construction or landscaping work, flying ants may emerge in large numbers , causing temporary concern. Ecological Role in UK Grasslands These ants play important ecological roles, contributing to soil structure and nutrient cycling. Their extensive tunnelling aerates the soil , and their mounds create micro-habitat diversity that benefits other invertebrates and plants. The mounds are often colonised by specialist plant species adapted to the particular soil conditions created by the ants. Given their limited pest status and ecological value, control is rarely necessary or desirable. If mounds genuinely interfere with land use, they can be dispersed by repeated raking and levelling, though this may need to be repeated as ants continue to excavate. Complete colony elimination is rarely justified and is best avoided to preserve the ecological benefits these ants provide . Roger’s Ant (Hypoponera Punctatissima) At a glance  Roger’s Ant Latin name : Hypoponera Punctatissima Size : Workers 3–4 mm Colour : Dark brown with slightly reddish thorax Key features : Strongly ridged thorax; two nodes on petiole; compact, stocky body Habitat/Notes : Nests under stones, pavements, or urban areas; active foragers Roger’s Ant is a small, cryptic species that has become established in the UK, primarily in heated buildings, though it remains relatively uncommon and is often overlooked due to its small size and secretive nature. Characteristics of This Small Indoor Species Workers are extremely small, measuring only 2-3mm in length, making them among the smallest ants encountered in UK buildings. Roger's Ant - Scientific Name (Hypoponera Punctatissima) Notes: Indoor species, often in warm buildings buildings. They are dark brown to black in colour with a slender body shape. The antennae have a distinctive club at the end, and the body has a matt appearance. Their small size and shy nature mean they are often misidentified or not noticed at all. Typical Locations Found In the UK, Roger’s Ant is almost exclusively found indoors in heated buildings , particularly in areas with high humidity such as bathrooms, kitchens, and plant rooms. They nest in small cavities within the building fabric, including wall voids, beneath skirting boards, and in other concealed locations. Colonies are typically small , containing a few dozen to a few hundred workers. Why Identification Is Often Overlooked Due to their minute size, slow movement, and tendency to remain hidden in cracks and crevices, Roger’s Ants often go unnoticed even when present. They may be dismissed as “just dirt” or confused with other small invertebrates. When identification is sought, their unusual morphology can initially puzzle even experienced pest control professionals unfamiliar with the species. Whilst they do not pose significant health risks or cause structural damage, their presence indicates suitable conditions for other pest species and may cause concern in sensitive environments such as hospitals or food production facilities . Control follows similar principles to other indoor ant species, focusing on locating and treating nest sites and eliminating conducive conditions. Professional identification and treatment is advisable to ensure the species is correctly identified and distinguished from more problematic species . Pharaoh’s Ant (Monomorium Pharaonis) At a glance  Pharaoh’s Ant Latin name : Monomorium Pharaonis Size : Workers 2 mm Colour : Yellowish to light brown, darker abdomen tip Key features : Very small; two-segmented petiole; antennae with 12 segments and 3-segmented club Habitat/Notes : Indoor species; nests in warm, humid buildings; difficult to control The Pharaoh’s Ant represents one of the most challenging pest species encountered in the UK and is a matter of serious concern within healthcare facilities, food production environments, and other sensitive premises. Identification of this Invasive Tropical Species Pharaoh’s Ant workers are very small, measuring only 1.5-2mm in length, making them among the smallest ants in UK buildings . They are pale yellow to light brown in colour with darker abdominal bands and have a characteristic two-segmented petiole. Pharaoh's Ant - Scientific Name (Monorium Pharaonis) Notes: Persistent indoor pest species Queens are slightly larger at 3.5-5mm and darker in colour. The small size, pale colouration, and indoor occurrence distinguish them from most other UK species. Why They’re a Serious Concern in Heated Buildings Originating from tropical regions, Pharaoh’s Ants cannot survive outdoors in the UK climate and are exclusively found in heated buildings . They thrive in the constant warmth of hospitals, care homes, blocks of flats, co mmercial kitchens, and other centrally heated premises. Their small size enables them to penetrate almost any gap , allowing access to sterile environments, sealed food containers, and medical supplies. They have been documented carrying pathogenic bacteria including Salmonella , Staphylococcus , and Streptococcus , making them a genuine vector for disease transmission . In healthcare settings, they have been found in wound dressings, IV lines, and entering the beds of immobilised patients, presenting serious infection control challenges. Distribution in UK Hospitals, Care Homes, and Commercial Premises Whilst less common than Black Garden Ants , Pharaoh’s Ants are established in numerous buildings across the UK, particularly in urban areas. Once introduced, often through incoming goods or transfers of equipment between facilities, they spread rapidly through interconnected buildings via ducting, pipe runs, and cavity walls. A single building may ha rbour multiple interconnected colonies containing numerous queens. Disease Transmission Risks The ability of Pharaoh’s Ants to mechanically transmit pathogenic microorganisms is well-documented . They are attracted to moisture and a wide variety of foods, including those found in healthcare and food production environments. They have been found feeding on wound exudates, soiled dressings, and other contaminated materials before walking across clean surfaces, sterile equipment, and food preparation areas. This combination of small size, disease transmission potential, and ability to access sensitive areas makes Pharaoh’s Ants one of the few ant species classified as a public health pest in the UK . Why Professional Management Is Essential Pharaoh’s Ant colonies exhibit a survival strategy called “ budding ,” where colonies fragment when threatened, with queens and workers splitting off to form multiple new colonies. This means that inappropriate control methods, particularly the use of residual insecticide sprays, can transform a single colony problem into a building-wide infestation. Effective control requires a coordinated approach using specifically formulated baits containing slow-acting insecticides. These baits must be placed in all areas of ant activity and left undisturbed for weeks or months whilst workers transport the bait back to feeding queens and brood. Treatment pr ogrammes typically extend over three to six months and require meticulous monitoring and bait replenishment. Attempts at DIY control of Pharaoh’s Ants are strongly discouraged and are likely to exacerbate the problem . PGM Pest Control unequivocally recommends that only experienced, qualified pest control professionals undertake Pharaoh’s Ant treatments , ideally those with specific experience managing this species. Building managers should engage professionals at the first sign of infestation to prevent widespread establishment. Ghost Ant (Tapinoma Melanocephalum) At a glance  Ghost Ant Latin name : Tapinoma Melanocephalum Size : Workers 1.3–1.5 mm Colour : Head dark brown to black; body and legs pale/translucent Key features : Tiny and delicate; smooth thorax; rapid movement Habitat/Notes : Indoor and outdoor; often found in kitchens and greenhouses The Ghost Ant is an emerging pest species in the UK , increasingly encountered in heated buildings, particularly in urban areas. Whilst still less common than Pharaoh’s Ants, their numbers appear to be growing . Identification Features Ghost Ant workers are tiny, measuring 1.3-1.5mm in length. They have a distinctive appearance with a dark brown to black head and thorax contrasted against pale, almost translucent legs and abdomen, giving rise to their common name. Ghost Ant - (Tapinoma Melanocephalum) Notes: Rare in UK outdoors; occurs in heated buildings. This bicoloured appearance makes them relatively easy to identify despite their small size. They move rapidly and somewhat erratically. Indoor Occurrence Patterns Like Pharaoh’s Ants , Ghost Ants are tropical in origin and cannot survive UK outdoor conditions, restricting them to heated buildings. They favour warm, humid environments and are commonly found in kitchens, bathrooms, and other areas with moisture. They nest in extremely small cavities, including behind skirting boards, in wall voids, beneath flooring, within potted plants, and even inside hollow curtain rails or picture frames. Ghost Ants are attracted to sweet substances and can become a nuisance in homes and businesses, contaminating food and appearing in large numbers. Whilst not associated with disease transmission to the extent of Pharaoh’s Ants, their presence in food preparation areas is nonetheless unacceptable from a hygiene perspective. Control Complexities Like Pharaoh’s Ants, Ghost Ant colonies can contain multiple queens and will bud when threatened , making inappropriate control methods counterproductive. Colonies are highly mobile, readily relocating nest sites when disturbed. This mobility, combined with the ir small size and ability to nest in the tiniest cavities, makes locating all nest sites extremely challenging. Control requires gel baiting programmes similar to those used for Pharaoh’s Ants, combined with efforts to reduce moisture and eliminate food sources. Professional assistance is strongly recommended, as DIY attempts using residual sprays typically worsen the problem by causing colony fragmentation and dispersal . Wood Ants (Formica Rufa Species) At a glance  Wood Ants Latin name : Formica Rufa Species Size : Workers 4–9 mm; queens 9–12 mm Colour : Red thorax, black abdomen; sometimes orange highlights Key features : Large, robust body; strong mandibles; prominent eyes Habitat/Notes : Forest species; mound-building; important in ecosystem for pest control Wood ants represent a group of several related species, most notably the Southern Wood Ant (Formica rufa) and the Hairy Wood Ant (Formica lugubris). These are among the UK’s most impressive ant species but are of conservation concern rather than pest status in most circumstances. Physical Characteristics of Common Wood Ant Species Wood ants are large and distinctive. Workers measure 6-10mm in length, whilst queens can reach 12mm. Wood Ant - (Formica Rufa Species Group) Notes: Includes Forminca Rufa, Formica Polyctena, Formica Aquilonia. They have a characteristic bicoloured appearance with a reddish-brown thorax and head contrasted against a darker brown to black abdomen. The body is covered with dense hairs, particularly noticeable on the abdomen. They possess powerful mandibles and can spray formic acid in defence, which produces a distinctive vinegar-like smell when nests are disturbed. Protected Status and Conservation Importance Several wood ant species are of conservation concern in the UK, with the Narrow-headed Ant (Formica exsecta) listed as endangered and should be afforded protection under the Wildlife and Countryside Act 1981 . Other wood ant species, whilst not legally protected, are considered i mportant components of woodland ecosystems and indicators of ancient woodland. Wood ants build impressive mounds constructed from pine needles, twigs, and other plant material, which can exceed one metre in height and house colonies of 100,000 to 400,000 workers . These mounds are engineering marvels, maintaining stable internal temperatures and humidity through careful ventilation management. These ants play crucial ecological roles as predators of other invertebrates, including many forest pests, and as prey for birds and other wildlife. Their foraging activities influence woodland structure and nutrient cycling. When Removal or Management Is Necessary Wood ants rarely conflict with human activities, as they inhabit woodland and heathland habitats. Occasionally, nests may be encountered on development sites or near buildings constructed in formerly wooded areas. Very rarely, foragi ng workers may enter buildings, though they do not establish indoor nests. Their powerful bite and ability to spray formic acid can make them a nuisance if nests are near footpaths, picnic areas, or residential gardens. The acid spray can cause skin irritation and temporary vision problems if it contacts the eyes. Legal Considerations Before any control measures are contemplated, the specific species must be identified to determine whether it has protected status. If protected species are present, disturbance or destruction of nests is illegal without appropriate licensing. Even for non-protected species, conservation considerations should be paramount . Where nests genuinely conflict with legitimate human activities, relocation rather than destruction should be considered, though this requires specialist expertise. Physical barriers can prevent foraging ants from accessing buildings. In most cases, education about the conservation value and ecological importance of wood ants leads to tolerance and appreciation rather than demands for removal. PGM Pest Control strongly advises consu ltation with conservation organisations and local authorities before any action is taken regarding wood ant nests, and recommends involving professional ecologists in decision-making processes. Carpenter Ant (Camponotus Species) At a glance  Carpenter Ant Latin name : Camponotus spp. Size : Workers 6–12 mm; queens larger Colour : Usually black or dark brown; some species have red thorax Key features : Large, smooth-bodied; rounded thorax; single node petiole Habitat/Notes : Nest in wood (dead or damp); do not eat wood but excavate it Carpenter Ants are a significant concern due to their wood-damaging behaviour, though they remain relatively uncommon in the UK compared to other European countries and North America. Physical Identification Characteristics The most commonly encountered species in the UK is Camponotus ligniperdus , though other species may occasionally be found. Carpenter Ant - (Camponotus Herculeanus) Notes: Mostly found in Scotland's forests. Workers exhibit considerable size variation (polymorphism) within colonies, ranging from 6mm to 13mm in length. They are black or dark brown with a characteristic large, heart-shaped head when viewed from above. The thorax is smoothly rounded without spines, and the body has a sparse covering of pale hairs. Queens are substantially larger at 15-18mm Distribution and Habitat Preferences In the UK, Carpenter Ants are primarily found in woodland habitats, particularly in Scotland and northern England, though scattered populations exist elsewhere. They naturally nest in dead or decaying wood , particularly in tree stumps, fallen logs, and standing dead trees. Unlike termites, which consume wood, Carpenter Ants excavate it to create galleries for nesting, feeding instead on honeydew from aphids and other insects. Occasionally, they may establish nests in buildings, particularly older properties with wooden structural elements that have been compromised by moisture or fungal decay. They preferentially excavate wood that has already been softened by rot , though they will extend galleries into sound wood adjacent to damaged areas. Nesting Behaviour and Colony Size Carpenter Ant colonies develop slowly, typically taking 3-6 years to mature. Mature colonies contain 2,000-10,000 workers , though some may grow considerably larger. Colonies are typically monogynous with a single queen They may establish satellite colonies connected to the parent nest, complicating control efforts. In buildings, the parent colony is often located outdoors in tree stumps or woodpiles, with satellite colonies in the building structure. This arrangement allows the outdoor colony to support the indoor satellites with resources . Workers travel considerable distances between nests, up to 100 metres or more, following established trails. Structural Damage Potential Whilst Carpenter Ants do not consume wood and therefore cause damage more slowly than termites, long-established colonies can create extensive gallery systems that compromise structural integrity. Damage is typically concentrated in wood affected by moisture or fungal decay, such as window frames , door frames , roof timbers near leaks, and floor joists in areas with plumbing problems . The presence of Carpenter Ants often indicates pre-existing moisture problems that require attention regardless of ant control measures. Their excavation activities can exacerbate existing structural weaknesses . Evidence of Carpenter Ant activity includes the appearance of fine sawdust (frass) beneath exit holes, faint rustling sounds within wooden structures, and the presence of large black ants, particularly during evening hours when they are most active. Management Considerations Effective Carpenter Ant control requires identifying and treating all colony locations, both parent and satellite nests. This can be challenging as nests may be concealed within building structures or located outdoors. Observing foraging workers and following them back to nest sites is often necessary . Ant Treatment options include insecticidal dusts applied directly into galleries, residual sprays on foraging trails and surfaces, and baiting programmes. However, the success of these methods depends on accurate nest location and understanding of colony structure. Critically, addressing underlying moisture problems is essential for long-term control . Repairing leaks, improving ventilation, and replacing damaged wood removes the conditions that attract and support Carpenter Ants. Due to the structural implications and the complexity of locating and treating all nest sites, professional pest control involvement is strongly recommended for Carpenter Ant infestations. Pest control professionals can conduct thorough inspections, use specialised detection methods, and implement comprehensive treatment programmes whilst coordinating with building contractors to address moisture issues. PGM Pest Control recommends that property owners who suspect Carpenter Ant activity seek professional assessment promptly to determine the extent of any infestation and associated structural damage before problems become severe. Quick Ant Identification Guide Accurate identification begins with careful observation. When attempting to identify ants, consider the following characteristics: Size: Worker ant size provides an initial sorting criterion. Very small ants (1-3mm) include Pharaoh’s Ants , Ghost Ants , and Roger’s Ants . Medium-sized ants (4-6mm) include Black Garden Ants , Red Ants , and Yellow Meadow Ants . Large ants (6mm and above) include wood ants and Carpenter Ants . Colour: Colour can be distinctive but note that it varies with lighting and the ant’s age. Black or very dark brown ants include Black Garden Ants, Roger’s Ants, and Carpenter Ants. Reddish-brown ants include Red Ants and wood ants (particularly thorax). Pale yellow to light brown ants include Yellow Meadow Ants and Pharaoh’s Ants. Bicoloured ants include Ghost Ants (dark head and thorax, pale abdomen) and wood ants (reddish thorax, darker abdomen). Location: Where ants are found provides crucial identification clues. Ants found only indoors in heated buildings are likely Pharaoh’s Ants or Ghost Ants. Ants encountered primarily in gardens and entering buildings seasonally are likely Black Garden Ants. Ants in lawns, particularly if they sting, are likely Red Ants. Ants creating mounds in grassland are likely Yellow Meadow Ants. Ants in or near decaying wood , particularly in woodland, may be Carpenter Ants or wood ants. Nesting Sites: Observing nesting behaviour aids identification . Soil nests under paving or at lawn edges suggest Black Garden Ants. Soil nests in lawns and grassland suggest Red Ants or Yellow Meadow Ants. Nests in building cavities, particularly in heated areas, suggest Pharaoh’s Ants or Ghost Ants. Nests in decaying wood suggest Carpenter Ants (UK buildings) or wood ants (woodland). Large mounds of plant material in woodland indicate wood ants. Behaviour: Behavioural observations can be diagnostic . Aggressive ants that sting when disturbed are likely Red Ants. Ants that rarely appear above ground but create soil mounds are likely Yellow Meadow Ants. Very small, pale ants in large numbers in kitchens or hospitals suggest Pharaoh’s Ants. Bicoloured ants that move rapidly and erratically suggest Ghost Ants. Large black ants appearing in sawdust near wood suggest Carpenter Ants. Species Worker Size | Colour Indoor/Outdoor Key Features Black Garden Ant 4-5mm | Black/dark brown Primarily outdoor, enters buildings Most common; smooth appearance; no sting    Red Ant 4-5mm | Reddish-brown  Outdoor Stings; hairy appearance; prefers damp areas    Yellow Meadow Ant 2-4mm | Pale yellow Outdoor Subterranean; creates mounds; rarely seen Pharaoh’s Ant 1.5-2mm | Pale yellow/light brown Indoor only Very small; slow-moving; serious pest  Ghost Ant 1.3-1.5mm | Bicoloured Indoor only Dark head/thorax, pale abdomen; rapid movement Roger’s Ant 2-3mm | Dark brown/black Indoor only Very small; rarely noticed; clubbed antennae Wood Ant 6-10mm | Bicoloured Outdoor woodland   Large mounds; spray formic acid; conservation concern Carpenter Ant 6-13mm | Black/dark brown Outdoor and buildings  Variable size; nest in wood; structural pest Common Misidentifications Black Garden Ants are sometimes mistaken for Carpenter Ants, though Carpenter Ants are considerably larger and have a distinctively shaped head. Pharaoh’s Ants and Ghost Ants may be confused due to small size, but their colouration differs significantly. Red Ants and wood ants both have reddish colouration but differ greatly in size and habitat. Yellow Meadow Ant workers are rarely seen, so their mounds may be attributed to other species or non-ant causes. When to Seek Professional Identification Professional identification is advisable when species identification is uncertain, particularly if pest control measures are being considered, when ants are present in healthcare or food production facilities, if structural damage is suspected, or when protected species might be present. Misidentification can lead to inappropriate and ineffective control measures , wasted resources, and potentially illegal actions if protected species are involved. Ant-Related Concerns and Risks Whilst ants are fascinating and ecologically important insects, certain species in certain contexts present legitimate concerns that justify control measures. Structural Damage Potential Carpenter Ants represent the primary structural concern in the UK, excavating wood to create nesting galleries. Whilst damage develops more slowly than that caused by wood-boring beetles or termites, long-established colonies can compromise structural elements , particularly when wood has been pre- weakened by moisture or decay . Some ant species, including Black Garden Ants, occasionally nest within insulation materials, beneath flooring, or in cavity walls, potentially causing minor damage to building fabric. Yellow Meadow Ant mounds may undermine paving or create uneven surfaces on sports fields. Food Contamination and Hygiene Issues Ants foraging in kitchens, food storage areas, or food production facilities present contamination risks. Whilst most UK species are not significant disease vectors, ants walking across unsanitary surfaces before traversing food preparation areas or entering food containers can transfer bacteria mechanically . The presence of ants in food businesses is aesthetically unacceptable to customers and can result in regulatory action, prosecution, and severe reputational damage. A single image of ants in a restaurant or food shop shared on social media can have devastating consequences for businesses In domestic settings, contamination of stored foods necessitates disposal, resulting in waste and expense. The psychological distress caused by finding ants in food or appearing in large numbers within homes should not be dismissed. Public Health Implications Pharaoh’s Ants represent a genuine public health concern in healthcare settings , capable of transmitting pathogenic bacteria and accessing sterile environments, wound sites​​​​​​​​​​​​​​​​ , and vulnerable patients. Their presence in hospitals, care homes, and similar facilities is unacceptable and requires immediate professional intervention . Red Ant stings, whilst rarely life-threatening, cause pain and distress. For individuals with allergies, stings can trigger anaphylactic reactions requiring emergency medical treatment. The presence of Red Ant nests in areas used by children or vulnerable adults presents a safeguarding concern that must be addressed. Electrical Equipment Damage Some ant species, particularly Pharaoh’s Ants and Ghost Ants, are attracted to electrical equipment , possibly due to the warmth generated or electromagnetic fields . They have been documented nesting within computers, telephone exchanges, electrical control panels, and other equipment. Their presence can cause short circuits, equipment malfunction, and fire risks. The accumulation of dead ants and debris within sensitive equipment can lead to costly failures and downtime. Economic Impact on Businesses Beyond direct damage and health concerns, ant infestations carry significant economic consequences for businesses . Treatment costs, particularly for challenging species like Pharaoh’s Ants, can be substantial and extend over many months. Production or operational downtime during treatment affects revenue. Contaminated stock must be disposed of , representing direct financial losses. Failed inspections or regulatory action can result in prohibition notices, fines, and prosecution. Perhaps most damaging is the reputational impact. In an era of instant social media communication, a single ant sighting can rapidly escalate into a public relations crisis . Customer loss following publicised infestations can far exceed the direct costs of the infestation itself. For these reasons, businesses in food production, hospitality, healthcare, and retail sectors must maintain vigilant pest monitoring programmes and respond swiftly to any signs of ant activity. The cost of prevention and early intervention is invariably lower than the cost of managing established infestations and their consequences. When to Contact a Professional Understanding when professional pest control involvement is necessary versus when homeowners might reasonably manage minor ant problems themselves is important for both effective pest management and efficient resource allocation. Signs of Significant Ant Infestation Professional assistance should be sought when ants appear in large numbers persistently despite cleaning and removal of attractants. Ant infestations are often noticed when workers enter kitchens, food storage areas, or damp spaces. Common signs include : Small trails of ants along floors, walls, or skirting boards Ants clustering around food sources, crumbs, or sugary spills Visible nests in wall cavities, under flooring, or behind appliances Increased ant activity in bathrooms, kitchens, and damp areas Garden ants entering buildings through gaps in doors, windows, or foundations If ants are o bserved entering and exiting specific points in building fabric, suggesting established nesting within the structure, professional investigation is warranted . The appearance of flying ants indoors, particularly repeatedly or outside the normal summer season, indicates an indoor colony requiring professional treatment. If you have a problem with flying ants, here's what you need to know ↗ If ants reappear rapidly after DIY treatments , or if multiple different DIY products have been attempted without success, this suggests either misidentification , inappropriate treatment methods, or concealed nests that require professional detection and treatment. The discovery of structural damage, particularly sawdust or damaged wood associated with ant activity, requires immediate professional assessment to determine the extent of damage and implement appropriate remediation. Species Requiring Specialist Treatment Pharaoh’s Ants must always be managed by experienced professionals . DIY attempts at Pharaoh’s Ant control are strongly contraindicated and will almost certainly worsen the problem through colony fragmentation. The public health risks associated with this species, combined with the complexity of achieving control, make professional involvement non-negotiable. Similarly, Ghost Ants require professional management due to their colony structure and behaviour. Carpenter Ants , given the structural implications and the need to locate all colony sites, should be professionally managed. Red Ant infestations, particularly in public spaces or where vulnerable individuals might be affected, warrant professional treatment to ensure complete colony elimination and prevent stinging incidents. DIY Limitations and Risks Householders have access to various ant control products through retail outlets. DIY pest control products on a shelf in a well known hardware retailer For minor incursions of Black Garden Ants, these products may provide temporary relief. However, several important limitations must be understood . Most retail products are surface treatments that kill foraging workers but do not reach the colony. This provides temporary reduction in numbers but not long-term control . Worse, some products, particularly residual sprays, can cause colony fragmentation in species that bud, transforming a manageable problem into a severe infestation. Ant Awareness: Essential facts and tips for the UK ↗ Misidentification is common, and treatment appropriate for one species may be counterproductive for another. Without proper identification and understanding of ant biology and behaviour, householders may spend considerable sums on multiple products without achieving control, whilst the infestation continues to develop. There are also safety considerations. Inappropriate use of pesticides , particularly in food preparation areas or where children and pets are present, presents risks . Professional pest controllers are trained in the safe and targeted application of pesticides, minimising exposure whilst maximising efficacy. What to Expect from PGM & Son Ant Control Service PGM & Son Pest Control adhere to professional standards and codes of practice that ensure competent, safe, and ethical ant control services . When engaging PGM for ant control, clients can expect: A thorough inspection to identify the ant species, locate nests, determine the extent of infestation, and identify factors contributing to the problem.  A written treatment proposal explaining the recommended approach, the products to be used, the expected timescale for achieving control, any preparation required from the client, and the cost. This proposal will be transparent about what is and is not guaranteed, recognising that some species are challenging and may require extended treatment programmes. Professional application of appropriate control measures using approved products applied by our RSPH trained and certified technicians. This includes careful placement of professional treatments to target ants whilst minimising exposure to non-target organisms, adherence to product label instructions, and maintenance of application records. Advice on preventing reinfestation , including recommendations regarding food storage, waste management, building maintenance, and hygiene practices. Note: Long-term success requires client cooperation in addressing underlying causes. Follow-up visits as necessary to monitor treatment efficacy, replenish baits, or apply additional treatments. The number of visits required varies with species and infestation severity, but clients should have realistic expectations set during the initial consultation. The Importance of Using Qualified, Certified Pest Controllers for Ant Infestations The pest control industry in the UK has moved towards professionalisation, with recognised training programmes and certification schemes. BPCA and NPTA membership/s requires adherence to professional standards , appropriate insurance, and commitment to continuing professional development. Using qualified pest controllers provides assurance of technical competence, knowledge of current regulations and best practices, appropriate insurance coverage protecting clients from liability, and access to professional-use products not available to the public , which are often more effective than retail products. Professional pest controllers must also navigate complex regulations regarding pesticide use, waste disposal, and environmental protection. They maintain records as required by legislation and can provide documentation needed for regulatory compliance or insurance purposes . For businesses subject to audit or inspection , documented evidence of professional pest management is often required. BPCA member companies provide the reports and documentation needed to demonstrate due diligence and regulatory compliance. To find a BPCA pest controller near you, search the membership database of trusted pest control companies at https://bpca.org.uk/find Clients are encouraged to seek multiple quotations for majo r pest treatments. The cheapest quotation is not always the best value if it involves inadequate treatment that fails to resolve the problem or, worse, exacerbates it Prevention and Integrated Pest Management Prevention is always preferable to cure, and many ant problems can be avoided or minimised through good housekeeping and building maintenance. PGM Pest Control advocates for Integrated Pest Management (IPM) , an approach that emphasises prevention, monitoring, and the use of multiple control tactics rather than relying solely on pesticides. Proactive Measures for Homeowners Food hygiene is fundamental to ant prevention. Store food in sealed containers rather than leaving it in opened packaging. Clean up spills and crumbs promptly, and do not leave dirty dishes overnight. Store pet food securely and clean feeding bowls regularly. Take rubbish out regularly and ensure bins have tight-fitting lids. Eliminate water sources by repairing leaking taps, pipes, and appliances promptly. Ensure sinks, baths, and showers drain properly without leaving standing water. Use dehumidifiers in damp areas if necessary. Restrict access to buildings by sealing cracks and gaps around windows, doors, pipes, and cables. Install door sweeps on external doors and ensure window screens are intact. Repair damaged pointing and render on external walls. Maintain gardens to reduce ant populations near buildings. Avoid positioning compost heaps, woodpiles, or refuse bins directly against external walls. Trim vegetation away from buildings to eliminate bridges for foraging ants. Lift paving slabs and remove debris where ants commonly nest. During flying ant se ason, keep windows and doors closed during evening hours when nuptial flights occur, or ensure screens are in place. Turn off external lights that attract flying ants Commercial Premises Best Practices Businesses must maintain more rigorous standards due to regulatory requirements and the higher stakes involved. Comprehensive pest management policies should be documented and implemented, with staff trained to recognise signs of pest activity and understand their role in prevention. Regular inspections should be conducted, either by in-house personnel or contracted commmercial pest control professionals , with findings documented and acted upon. Many businesses benefit from pest control contracts that provide regular monitoring visits and rapid response to emerging problems. Essential guide to reviewing pest control contracts ↗ Structural maintenance must be prioritised , with a schedule for checking and repairing building fabric, doors, and windows. Loading bay areas, which are high-risk entry points, require particular attention with rapid-closing doors, good lighting, and regular inspection . Food handling and s torage protocols must be rigorous , with stock rotation systems that enable rapid identification of contaminated items, segregation of returned or damaged goods, and thorough cleaning schedules for storage areas. Waste management is critical , with multiple collections daily in food production areas, covered bins with foot-operated lids, regular bin cleaning, and designated waste storage areas away from food handling zones. Environmental Modifications to Reduce Ant Attractiveness Creating environments that are inhospitable to ants reduces infestation risk. Eliminate clutter that provides harbourage, particularly in storage areas, basements, and lofts. Maintain clear spaces around buildings, avoiding piled materials against external walls. Ensure good ventilation to reduce humidity, as many ant species prefer moist conditions. Address any fungal growth or rot, which both creates conducive conditions for ants and may indicate moisture problems requiring attention. In gardens and grounds, maintain lawns regularly to prevent Yellow Meadow Ant mounds from developing. Consider whether certain features, such as rockeries or raised beds, are creating ideal ant nesting sites near buildings. Climate Change Impacts on Ant Populations and Behaviour Rising temperatures are likely to increase ant activity levels and extend the active season. Colonies may grow larger and reproduce more successfully . Species that currently struggle to survive UK winters may become more successful. Changes in precipitation patterns may affect species differently. Red Ants, which favour moist conditions, might benefit from increased rainfall in some regions whilst suffering from droughts in others. Yellow Meadow Ants, dependent on stable grassland habitats, may be affected by changes in vegetation communities driven by altered climatic conditions . Indoor pest species may become more problematic if buildings rely increasingly on air conditioning, providing more stable warm environments suitable for species like Pharaoh’s Ants and Ghost Ants. Future Monitoring Needs Systematic monitoring of ant populations and distributions would provide valuable data for understanding climate change impacts and detecting invasive species. Currently, such monitoring is limited, relying largely on ad hoc observations by naturalists, academics, and pest control professionals. Anticipating future pest challenges requires ongoing surveillance , research into the biology and behaviour of potential invasive species, and development of management strategies before problems arise. The pest control industry, working alongside researchers, conservationists, and policymakers, has important contributions to make to these efforts. Sustainability in pest control ↗ Conclusion Ants are remarkable insects that have successfully colonised virtually every terrestrial habitat on Earth. In the United Kingdom, the vast majority of ants live their lives with minimal impact on human activities . Indeed, many species provide valuable ecosystem services that benefit agriculture, forestry, and natural habitats. Ants have several physical traits that lead to "myth-busting" questions, if you're interested intheir 'super-powers' read The Ant 101 ↗ However, a small number of species, when occurring in inappropriate locations or excessive numbers, become pests requiring management. Accurate identification of these species is the foundation upon which effective control strategies are built. As we have explored throughout this guide, different species require radically different approaches , and misidentification can lead to ineffective treatments, wasted resources, and, in some cases, exacerbated infestations. Summary of Key Identification Points Black Garden Ants The UK's most common pest species, are medium-sized, dark-coloured ants typically nesting outdoors but foraging indoors. They respond well to baiting programmes and perimeter treatments. Red Ants Similarly sized but reddish-brown and possessing a painful sting, require careful management, particularly in public spaces. Yellow Meadow Ants Pale and subterranean, rarely cause significant problems and should generally be tolerated due to their ecological value. Pharaoh’s Ants and Ghost Ants Both very small and restricted to heated buildings, represent serious pest challenges requiring prolonged professional treatment programmes. DIY attempts at control are strongly discouraged. Carpenter Ants Large and black, excavate wood for nesting and represent a structural concern requiring professional assessment and treatment. Wood Ants Impressive mound-builders of woodland habitats, are of conservation concern and require careful consideration before any management action is contemplated. The Value of Early, Accurate Identification Responding promptly to ant activity, securing accurate identification, and implementing appropriate management strategies provides the best outcomes. Early intervention is invariably more successful and cost-effective than addressing well-established infestations For householders, understanding which species are present helps determine whether DIY measures might suffice or whether professional assistance is necessary. For businesses, rapid identification and response protects operations, reputation, and regulatory compliance. PGM’s Commitment to Professional Standards in Ant Management PGM & Son Pest Control Services remains dedicated to advancing standards across the pest control industry and supporting a sustainable, professional approach to pest management, championing Integrated Pest Management practices that focus on prevention, ongoing monitoring, and the responsible application of control measures tailored to each situation. Green Pest Control – How to be Pest Aware ↗ Encouragement to Seek Professional Advice When Needed Whilst this guide provides comprehensive information about ant identification and management, it cannot substitute for professional assessment in complex or challenging situations. The training, experience, and specialist tools available to professional pest controllers enable them to diagnose problems accurately, develop effective strategies, and implement treatments safely. We encourage property owners and facility managers to view pest control not as an emergency expense to be minimised, but as an investment in protecting health, property, and peace of mind. Engaging qualified professionals early in the management process typically results in better outcomes at lower overall cost than delayed intervention or failed DIY attempts. For commercial food businesses, professional pest management should be viewed as an essential component of operational risk management, regulatory compliance, and quality assurance programmes. The cost of professional services is negligible compared to the potential costs of pest-related business interruption, regulatory action, or reputational damage . Together, we can ensure that ant problems are managed effectively, safely, and sustainably, protecting both human interests and the ecological values these fascinating insects represent.

Ants can be really annoying however, they aren’t usually regarded as disease carriers so most people are advised to put up with them if they’re found in the garden. Ants can become a problem in the house though as they travel around outside across all sorts of terrain and so you wouldn’t really want them marching across your kitchen work surfaces or in your larder cupboard. The UK climate hasn’t historically been ideal for ants as they prefer warmer climates. However, with global warming, the ant is thriving in the UK and especially during these Summer months. How do you know if you’ve got ants? You’ll probably know you’ve got ants as you’ll normally see them first of all. Ants are fascinating creatures – watch how they operate, it is amazing! You may also see small holes in soil with small piles of earth surrounding them. What can you do to keep the ants away? There’s not a great deal you can do to keep the ants away from your garden but you can take some simple steps to reduce the risk of an ant infestation inside your home or business. This includes: Keeping work surfaces clean and free from sticky residues – ants love sweet things Make sure you keep foodstuffs in sealed tight containers and put away in cupboards. Remove anything that is a food source for ants Check to see where they might be entering your property and close the access point, although this can be very difficult as the ant is so small. Keep a close eye on the ants moving back and forth from nest to food to track their movements. Ant in your pants? A fun fact : The saying “ants in your pants” is generally thought to be due to excitement, restlessness, fidgety or worry but no specific or logical explanation or source for the saying has been found. Fun Ant Facts They’re super strong – an ant can carry 20 times its own body weight! Have you seen the ant man? Queen ants can have millions of babies – wow! imagine that! A colony will only usually survive a few months without a Queen. Worker ants cannot reproduce and a Queen is rarely replaced. Ants don’t have ears! What? Instead they hear by feeling vibrations with their feet Need Help Controlling Ants?

Introducing the Ant! This week we are excited to carry on with our series of "Pest Trumps" at PGM & SON Pest Control Services with The Ant . Each file is available for free download , and you may use them at work to help identify pests for the protection of your workers and customers. The PGM "Pest Control Trumps" set of information cards were created to assist with pest-related issues in the UK and to ensure the public are armed with the correct information about each pest we highlight in our pest trump series. By proactively promoting an integrated pest management approach, we can protect people and food as well as wildlife and the environment. We all have an important part to play in educating the public and business that prevention is better than cure. At PGM & SON we know stewardship and sustainability are critical both to the survival of the pest control industry and to our planet. Fact File These highly organised and social insects are noticeable by their head, thorax and abdomen. With narrow waists and a sharp elbow joint in their antennae, the foraging worker ants march into buildings to search for food to take back to the nest to feed their larvae and queen. DID YOU KNOW? Flying ants are reproductive males and females who have a nuptial swarming flight for a few days usually in July and August. STRENGTH ~ 8 What can we say?! If anyone has ever seen a tiny army of ants on the march, they can’t fail to be impressed. These minute insects have strength in numbers and are fascinating to watch. BREEDING ~ 8 Flying ants' mate in flight after which the female will find a nest for the winter. She then lays her eggs the following spring to start a new colony. The ability to survive through the winter to start a new colony in the spring seems like a massive feat to us for such a tiny insect! The average lifespan of an ant can be anything from several weeks to several years. NUISANCE FACTOR ~ 10 Although impressive in their skills and teamwork, ants are a major nuisance factor. They love sweet foods and will forage in kitchens and just about anywhere to find food which they can take back to their nest. The problem with an ant is that they march across most surfaces to find and transport their food including other animal faeces, dirt, grime and bacteria. The ant is a major disease transmitter for this reason. Ants are also very hard to control due to their size, ability to access buildings through miniscule holes and cracks, build inaccessible nests and their sheer numbers. AGILIGTY ~ 8 Ants make complex and vast nests with multiple inaccessible entry points. In the garden, ant nests occupy a much larger volume of soil than the surface excavations might suggest. ENVIRONMENTAL ~ 7 The common ant is an important insect and can be found in pretty much every garden across the UK. They are an important part of biodiversity. Ants feed on other invertebrates including other ants. They also collect sweet liquid known as honeydew from aphids and sap-feeding insects. They do little damage to plants although they can disturb the soil around the roots to use for nests. Superpower Teamwork! Overall PGM Rating 7/10 For an ant, it’s all about great teamwork. They may be tiny insects, but they are mighty team players! Ants can be a major nuisance in a home or business, and they are disease carriers, so they score low on both points. However, in the garden, ants are an important part of biodiversity and win extra points for this. They are also fascinating insects with impressive ability given their small size.

As we move into spring, you may start noticing more bee activity around your home or business. Warmer temperatures trigger one of the busiest periods in the bee calendar—so if it suddenly feels like they’re everywhere, you’re not imagining it. Great to see lots of bees already ! At PGM Pest Control we’re pleased to be seeing lots of different variety of bees already – buzzing around the flowers and pollinating like mad. And we reckon our local farmers deserve a big pat on the back for reducing the use of damaging crop sprays. They’ve been doing their bit for our great Herefordshire  countryside. And let’s not forget about the conscientious pest controllers among us who are taking steps to look after our precious bee population and avoiding unnecessary pest treatments. At PGM you know WE LOVE our BEES! But we also understand that they can be hazardous at times and if there’s a public health risk we’ll always address the problem. Our pest technician rehoming bees At PGM Pest Control, we regularly receive calls at this time of year from concerned customers unsure whether they’re dealing with a problem or simply seasonal activity. This guide will help you understand what’s normal, what isn’t, and when to take action . Why Are Bees So Active Right Now? Spring marks the start of the bee season. Colonies that have survived the winter begin expanding rapidly as food sources return. During this period : Queens begin laying eggs again Worker bees leave the hive to forage Colonies grow quickly in size Swarming season begins (typically from April onwards) In short, bees are doing exactly what they’re supposed to do—working hard to rebuild and thrive. Understanding the Different Types of Bees Not all bees behave the same way, and knowing the difference can help you decide whether there’s a genuine issue. Honey Bees Live in large colonies Often associated with swarms Usually non-aggressive unless provoked Bumblebees Larger and fuzzier in appearance Nest in smaller groups, often in the ground Generally very docile Solitary Bees Do not form colonies Nest individually in soil, wood, or walls Pose virtually no risk In many cases, what appears to be a “problem” is actually harmless activity. Swarms: Impressive, but Usually Not Dangerous One of the most common concerns we see in spring is swarming. A swarm occurs when: A colony becomes too large The queen leaves with part of the workforce Bees temporarily cluster while finding a new home While this can look alarming, swarms are typically : Temporary (often moving on within 24–48 hours) Focused on relocation, not aggression Unlikely to sting unless disturbed Are Bees Dangerous? In most situations, bees are not a threat. However, there are exceptions : If a nest is located inside a property (walls, lofts, chimneys) If someone nearby has a bee sting allergy If bees are being disturbed regularly It’s important to balance caution with understanding—bees are vital to the environment and should not be treated as pests unless necessary. What to Do If You Find a Bee Nest If you discover a nest on your property, the best course of action depends on the situation. In most cases : Leave it undisturbed Keep a safe distance Monitor activity Do NOT : Attempt to spray or poison the nest Block entrances Disturb the structure When to take action : Bees are entering your home The nest is in a high-traffic area There is a health risk At that point, it’s time to speak to professionals. Our Approach: Responsible Bee Management At PGM Pest Control, we take a measured and responsible approach  to bees. Whenever possible, we: Avoid unnecessary treatment Recommend monitoring or natural relocation Work with trusted contacts where appropriate Bee removal is only considered when: There is a genuine risk to people or property The nest is established in a problematic location Bees vs Wasps: Know the Difference It’s easy to confuse bees with wasps, but they behave very differently. The difference between Bees, Wasps and Hornets Bees: Hairy, rounder bodies Focused on pollination Less aggressive Wasps: Smooth, slender bodies More aggressive, especially late summer More likely to sting repeatedly If you’re unsure what you’re dealing with, we can help identify the issue quickly. Signs You May Have a Problem Most bee activity is harmless—but keep an eye out for: Consistent traffic entering a specific hole or gap Buzzing inside walls or ceilings Honey staining or residue indoors Increasing numbers over time These may indicate a nest within the structure of your property. Protecting Your Property (and the Bees) Prevention is always better than cure. Simple steps include : Sealing gaps in walls and rooflines Maintaining vents and chimneys Avoiding DIY chemical treatments Encouraging bee-friendly areas away from your home Seeing more bees at this time of year is completely normal—and in many ways, a positive sign of a healthy environment. That said, if their activity starts affecting your home or business, it’s important to handle the situation correctly . Need Advice or Assistance?

Find a Local Swarm Collector If you spot a swarm of bees on your property, the safest approach is to contact a local swarm collector . These trained volunteers and beekeepers can safely relocate the bees without harming them. Swarm collectors are often free or low-cost  and operate across Herefordshire and Worcestershire . They know how to handle bees safely  and can remove swarms from walls, gardens, or trees. Using a collector helps protect the environment  while keeping your home safe. You can find local swarm collectors through: The British Beekeepers Association (BBKA) website : https://www.bbka.org.uk/find-a-local-swarm-collector Local beekeeping clubs in your area Your PGM Pest Control team , who can advise on contacts and safe removal Remember : do not attempt to remove a swarm yourself  — this can be dangerous and stressful for the bees. Frequently Asked Questions about Bees in Spring  What should I do if there is a swarm of bees in my garden right now? If you see a cluster of thousands of bees hanging together, that’s likely a honey bee swarm — a natural and usually harmless process  as a colony relocates. Avoid disturbing it, keep children and pets away, and do not spray or attack the swarm . In many cases, local beekeepers or swarm collectors can safely remove and relocate these bees for free. Can I attract a swarm away from my property? There’s no guaranteed way  to lure swarming bees off your property . Bees choose new sites based on scout bees’ assessment of suitability. The safest approach is to leave them undisturbed and contact a beekeeper or local swarm collector who may assist in relocation. How early can bee swarms occur in the UK spring? Bee swarming typically peaks May through July , but in warm years swarms can appear as early as late March or April . This year’s warmer weather means you might see activity earlier than usual. Are there bees that dig nests in the ground and what do I do about that? Yes — many solitary bees and bumblebees  nest in bare soil. These ground nests are usually non-aggressive and beneficial ; they rarely sting unless directly threatened. If it’s a solitary bee or bumblebee nest, the safest option is to leave them undisturbed  while keeping children’s play areas clear. Why are some bees coming into my house even when windows are closed? Bees may enter buildings through gaps around chimneys, vents, or brickwork while looking for nesting sites or floral scents. They may appear inside walls or fireplaces. If you see this, it doesn’t always mean a full nest — but it can  indicate bees have established a colony in a cavity, and it’s worth consulting a professional if it continues . How can I tell if the insects I see are bees or something else like wasps or hornets? Bees are generally fuzzier with rounded bodies , while wasps are smooth and slender with bright yellow/black stripes. Newly invasive Asian hornets  (yellow-legged hornets) are also a growing concern in the UK and should be reported if spotted, as they can threaten native bees.

From 29th June to 5th July, the annual week of action and education to raise awareness about the amazing solitary bees commences. At PGM & SON Pest Control - WE LOVE OUR BEES ! 🐝 And solitary bees are no different. Most people have heard of bumble bees and honey bees but this week we’re joining the University of Exeter’s Environment and Sustainability Institute (ESI) and Cornish product designers, Green&Blue to help raise awareness of the solitary bee. What’s a solitary bee? A solitary bee doesn’t produce any honey or wax and they don’t live in hives or swarm. However, they are quite sociable and often nest close to each other – despite their anti-social name! Some solitary bees help collect pollen and nectar for their mothers to help feed their siblings – awww what kind little bees they are! Just over two thirds of solitary bees are ‘mining’ bees nesting in burrows underground. Others are cavity nesting and prefer to live in hollow plant stems, snail shells and existing holes and tunnels in wood or mortar. Masonry bees, more commonly called ‘mortar’ bees, are a solitary type of bee – quite often you’ll see this type of bee nesting in individual holes in mortar joints and soft bricks. Solitary bees make up around 90% of the bee population and there are currently around 240 species in the UK. Together with other pollinating creatures, they are responsible for a third of all the food we eat so they are massively important to the planet. Hoorah for bees! 🐝 Due to increased use of chemicals in large fields and across farm lands unfortunately the solitary bee are increasingly under threat. There are less wildflower meadows and hedgerows around which historically provided home to many wildlife. Did you know? In some parts of China, there are no bees left to naturally pollinate and so pollination is being undertaken using paintbrushes! Wow! that’s a very gruelling task!! What you can do this week to help the solitary bee Share your photos on social media using the #solitarybeeweek And, as a reminder from PGM & Son Pest Control: Leave them Bee! If you are watching their fascinating work – social distance yourself! Don’t panic if your bees are active in hot weather, this is entirely normal! Contact a local beekeeper to see whether they can relocate the nest for you (but only if it’s necessary and you are unable to leave it where it is). If you are worried about bees, give us a call at PGM & Son Hereford as we can talk to you about why bees are important and set your mind at rest about the risk to you. In most cases, the risk of being stung will be extremely low. In rare situations bees can be hazardous and, where there is a threat to the public, you can contact a pest controller to address the problem. So if you have a bee problem you need help with, give PGM & SON Pest Control a call so we can discuss a range of solutions with you, which enable us to live in harmony with our friends the bees.

What to do if you have a bees nest in Hereford?...Leave them Bee! What great weather we’re having! And we’re starting to see lots of bees pollinating like crazy. At PGM & Son Pest Control WE LOVE OUR BEES! Bees are the key workers of the insect kingdom – they are critical to our eco-system and it is essential that they are protected. Research estimates that bees pollinate a third of all crops, including those which are used to feed livestock to you can see how important they are to the planet. And we reckon our local farmers deserve a big pat on the back for reducing the use of damaging crop sprays. They’ve been doing their bit for our great Herefordshire countryside. And let’s not forget about the conscientious pest controllers amongst us who are taking steps to look after our precious bee population and avoiding unnecessary pest treatments. Did you know that 25% of all bee types are endangered? LEAVE THE BEES ALONE! Our advice to the public is always LEAVE THE BEES ALONE if you can, and let them go about their very important business. During lockdown when lots of children are at home encourage your children to observe the bees going about their work. They are fascinating creatures – bees are not usually aggressive but as with any insect or animal you should respect them so keep your distance if you want to watch them as they pollinate. Top Tip - Tell children they need to social distance with bees as well! The other important thing to remember is that bees will go away and not return to the nesting site after the summer. In fact, by the time most people notice a colony, the activity will be naturally declining. What to do if you have bees Leave them Bee!

The vast majority of plants we need for food rely on pollination, especially by bees. Bees also pollinate the beautiful wild flowers across the countryside Thanks to bees we enjoy a range of foods from apples to pears to coffee and vanilla. And if you are wearing cotton, that’s because the cotton plant your threads came from was pollinated. Bees are not the only pollinators, but they are specialists – call them the subject matter experts of pollination! And contrary to popular belief – bees are not normally aggressive towards humans. If left alone to do their important job, they won’t bother you. Damage to our environment has been a hot topic in the news recently.
