Wasps remain active in October due to their life cycle, warmer autumns, and dwindling food sources, often becoming more aggressive. They may enter bedrooms seeking warmth, light, or hibernation spots, sometimes indicating hidden nests. While wasps pose health risks, they also benefit ecosystems by controlling pests. Prevention (sealing gaps, managing waste) and professional pest control are the safest ways to manage autumn wasp problems.

Why Am I Seeing Wasps in October?
While wasps are most noticeable in summer, they often remain a nuisance into autumn, including October, and sometimes even winter. But why do these pests persist in the cooler months, and why might you find them in your bedroom? Let’s explore the fascinating biology and behavior of wasps, why they linger, and how to manage them effectively.
The Life Cycle of A Wasp
The common wasp (Vespula Vulgaris) has a lifespan of around 12 months for a Queen wasp and 12-22 days for a Worker wasp.
The lifecycle starts with the solitary Queen who builds her nest and rears the first worker wasps, which takes on average around 30-35 days.
After this the Queen rapidly starts to produce eggs, around 200-300 per day whilst the workers take over foraging. The population starts to grow until it reaches its peak around 90-100 days later at which point the population growth stops and new Queen cells are built.
The Queen wasp produces Queen larvae and the workers up their foraging.
When the Queen dies are becomes sick the unity of the worker colony breaks down, cannibalism sets in and foraging becomes erratic.
The succession of the Queen wasp occurs when the virgin Queens leave the nest to mate and hibernate. After this, a solitary Queen starts the cycle again around 6-7 months after the first solitary Queen started to build her nest.
The Wasp Biology and Behaviour Is Absolutely Fascinating!
Why Are Wasps Still Active in October?
As temperatures drop in the UK (averaging 10–15°C in Herefordshire/Worcestershire), wasps face declining food sources, like insects and nectar, leading to disorientation.
Normally, most workers die off by October, but several factors can prolong their activity:
Climate Change: Milder autumns, with temperatures 1–2°C warmer than decades ago (Met Office data), extend wasp activity by delaying die-off and hibernation.
Dietary Shifts: With larvae dwindling, workers seek sugary foods like overripe fruit, jam, or beer, drawing them to orchards, bins, or picnics in rural areas like Herefordshire.
Increased Aggression: Without a queen, workers become irritable and more likely to sting unprovoked, especially when competing for scarce food.
Lethargy from Cold: Cooler nights slow wasps’ metabolism, making them “dozy” and prone to crawling rather than flying, increasing their presence in warm homes.
Other wasp species, like the German wasp (Vespula germanica) or European hornet (Vespa crabro), may also remain active, nesting in ground burrows or tree cavities, respectively, unlike the aerial nests of V. vulgaris. Learn more about the difference between Bees, Wasps and Hornets.
Why Are Wasps in My Bedroom in October?
As external food sources dwindle and temperatures drop, disoriented wasps may wander into unusual places, including homes.
Here’s why they end up in your bedroom:
Seeking Warmth and Light: Wasps may follow warm air currents or be drawn to bedroom lights, mistaking them for sunlight. They often enter via wall cavities, lofts, or unsealed gaps in older UK homes.
Hidden Nests: Buzzing sounds, “ticking” from larvae, or wasps emerging through ceiling gaps/downlights may indicate a nest in your loft or walls, common in Herefordshire’s rural homes.
Hibernation Sites: Fertilized queens seek warm indoor spots like attics or insulation to hibernate, potentially leading to spring infestations if not addressed.
It’s also worth distinguishing wasps (slender, hairless, aggressive) from bees (fuzzy, pollinators), as confusion can lead to unnecessary panic or harm to beneficial insects.
Health Risks of Wasps in Autumn
Wasps in bedrooms pose more than just annoyance. Their stings can cause pain, swelling, and, in rare cases (1–2% of the UK population, per NHS data), severe allergic reactions like anaphylaxis. Multiple stings are riskier in autumn due to erratic, aggressive behavior, especially in confined spaces. Children and pets are particularly vulnerable, making prompt control essential.
Top Wasp Control Tip: Check your wasp control is carried out by a reputable, qualified pest controller.
Top Wasp Control Tips
To manage wasps safely and effectively in October, consider these strategies:
Let Them Die Off Naturally: If the problem is minor, allow wasps to die off as temperatures drop, saving money and reducing environmental impact.
Hire a Professional: For persistent or hazardous infestations, choose a qualified pest controller, to treat nests safely. (Nest removal isn’t always necessary but may incur extra costs.)
DIY Wasp Prevention
Seal Entry Points: Inspect eaves, gutters, and windows for gaps, and fit screens to prevent wasps entering during autumn cleanups.
Manage Food and Waste: Cover bins, clean up fruit spills, and avoid leaving sugary drinks exposed, especially in Worcestershire’s orchard-rich areas.
Safe Traps: Use bottle traps baited with jam or soapy water sprays for small-scale control, avoiding toxic chemicals.
Check for Nests Early: Listen for buzzing or look for wasps entering via ceilings to detect hidden nests before they become a bedroom issue.
The Ecological Role of Wasps
While wasps are often seen as pests, they play a valuable role in the UK ecosystem. They prey on garden pests like aphids, flies, and caterpillars, benefiting farmers and gardeners in agricultural regions. Understanding this can reduce unnecessary fear and treatments.
Common Myths About Autumn Wasps
Myth: “Wasps die off immediately in cold weather.” Fact: Mild October weather in the UK can keep wasps active longer, especially in southern regions like Worcestershire.
Myth: “Wasps are useless pests.” Fact: Their pest control services support gardens and crops, balancing their nuisance factor.
Regional Factors in the UK
In Herefordshire and Worcestershire, milder October weather (compared to northern UK) and abundant food sources (e.g., orchards, rural bins) contribute to prolonged wasp activity. Older homes with unsealed cavities or lofts are particularly prone to invasions, making local prevention critical.
How to Get Rid of Wasps Safely
For minor issues, try DIY prevention and let wasps die off naturally. However, if wasps pose a public health risk—especially in bedrooms or for those with allergies—contact a professional.
