The 5-Star Imperative
For any food-handling establishment, the Food Hygiene Rating Scheme (FHRS) score is the ultimate measure of operational excellence. This public rating, displayed on a scale from 0 to 5, indicates a business’s commitment to safety and quality. Achieving and maintaining a 5-star (Very Good) rating is fundamental for building consumer trust and securing long-term business viability.
The Consequences of a Low Food Hygiene Rating
• Poor ratings damage reputation and reduce customers
• Triggers more Environmental Health Officer (EHO) visits
• Risks fines, prosecution, or closure
Pest Control Defined: Integrated Pest Management (IPM)
• 5-star ratings require prevention, not reaction
• Waiting for pests fails Food Hygiene Rating Scheme (FHRS) standards
• IPM is proactive: prevents pests through blocking entry points, regular monitoring, and detailed records
• IPM integrates into your Food Safety Management System (FSMS), not a separate service
This guide provides food business owners and managers with an actionable framework for integrating IPM into daily operations, ensuring compliance and securing the highest hygiene rating.
Pest Control Across All Three FHRS Criteria
The EHO's assessment is broken down into three core scoring criteria. Your IPM system provides the evidence that proves you meet the standards in all three areas:
• Criteria 1
Hygienic Food Handling:
Pests are mobile biological hazards. Their droppings, urine, and bodies contaminate food and preparation surfaces, leading to the spread of dangerous bacteria. Any evidence of pests is a direct failure of this criterion.
• Criteria 2
Cleanliness and Condition of Facilities and Structure:
This is where structural prevention (Section 4) and monitoring (Section 6) are judged. The EHO looks for pest entry points, signs of harbourage, or recent pest activity. Signs of entry or active pests immediately drop this score.
• Criteria 3
Management of Food Safety:
This criterion assesses whether you have robust systems in place, including documentation (Section 9), staff training (Section 8), and documented Response Protocols (Section 6). Failing to have a current, robust pest control contract and clear logbook entries is an automatic failure point here.
Understanding Pest Risks & Contamination Pathways
Pests are, quite literally, mobile biological hazards. They pose two main risks: 1, physical presence and 2, disease transmission.
Common Culprits
We focus on the most problematic pests in UK food businesses:
Cause structural damage by gnawing and leaving droppings and urine that contaminate surfaces.
• Insects (Cockroaches, Flies, Ants):
Cockroaches carry pathogens on their bodies, and flies transfer bacteria from filth to food.
• Stored Product Insects (Moths, Beetles):
Infest dry goods like flour, grain, and pulses, destroying stock and contaminating ingredients.
Pest Contamination: Risks and Transmission Routes
Pests contaminate through:
• Physical Contamination: Leaving visible droppings, fur, feathers, carcasses, or egg cases directly on food or equipment.
• Mechanical Transmission: Pests (especially cockroaches and flies) pick up bacteria like Salmonella and E. coli from drains and waste and mechanically transmit them to your food and food contact surfaces.
• Secondary Contamination: Infested products are often stored near clean ones, causing a ripple effect throughout your entire stock.
Structural & Facility-Based Prevention (Condition of Facilities)
In IPM, the goal is to make your premises impenetrable. This addresses the EHO's 'Condition of Facilities' criterion.
Sealing Entry Points
Focus on proofing, not just treating. Pests need only the smallest gap to enter (a mouse needs a gap the size of a pencil).
• Practical Examples:
Install door sweeps on all external doors; use wire wool and sealant to seal gaps around utility pipes and cables; ensure vents and windows have intact screens.
• Building Maintenance:
Maintain intact floor and wall finishes. Pests hide in cracks and behind loose tiles. Ensure drainage traps are functioning and clean, as they are a common entry point for rats and cockroaches.
Waste Area Design
The external waste area must be on hardstanding, easily cleaned, and ideally positioned away from entrance doors. This removes the primary outdoor attractant.
Cleaning, Waste & Storage Management (Hygienic Handling)
These disciplines are the foundation of good hygiene and a major factor in the 'Hygienic Food Handling' score.
• Waste Discipline: Inside, use lidded, pedal-operated bins that are emptied frequently. Outside, ensure your External Waste Protocol uses secure, undamaged bins with lids tightly closed. Establish a regular, documented waste removal schedule.
• Pest-Proof Storage: All food, including dry ingredients and packaging, must be stored off the floor (at least 6 inches) and in sealed, durable, pest-proof containers.
• FIFO (First-In, First-Out): This stock rotation system ensures you use older ingredients first. This practice is critical as it prevents products from sitting unused long enough to become infested by Stored Product Pests.
Monitoring, Surveillance & Response (Management of Safety)
An effective IPM system requires constant vigilance and clear action plans.
Monitoring & Surveillance
• Routine Checks:
Empower staff to be the first line of defense. Emphasise daily staff checks for tell-tale signs: droppings, urine pillars, grease marks (smudges along walls), or gnaw damage.
• Professional Surveillance:
Your licensed PGM contractor conducts routine inspections and maintains monitoring points (traps, non-toxic bait stations) across the internal and external perimeter. The frequency of these checks must be appropriate for your level of risk.
Response Protocol
The EHO requires a clear, documented procedure for when a pest is spotted:
1. Isolate:
Secure the contaminated area and isolate any affected food/equipment.
2. Clean/Disinfect:
Thoroughly clean and disinfect the affected area.
3. Contact:
Immediately inform the manager and your licensed pest-control professional.
4. Record:
Document the incident, the corrective actions taken, and the results of follow-up inspections.
Safe & Compliant Pest Control Methods
Your EHO will scrutinise the safety and legality of your pest control treatments.
• Licensing is Key: Always use a qualified professional with relevant industry certification (e.g., BPCA, NPTA, RSPH). This proves expertise and compliance.
• Avoid DIY: Using non-approved chemicals or methods near food is a severe hygiene breach that can lead to chemical contamination of food products.
• Non-Toxic Priority: Our IPM approach prioritises prevention and non-toxic methods (proofing, environmental controls, trapping) before any chemicals are considered. Any chemical used must be approved for use in a food environment and applied according to strict safety protocols.
Staff Training & Hygiene Culture
The best IPM system is useless without a team committed to it.
• Pest Awareness: Train staff to recognise the early signs of pest activity (Section 6) and understand the contamination risks. They need to know when and how to report a finding.
• Compliance: Training must cover every operational aspect: proper waste handling, secure storage practices, and strict personal hygiene. Management oversight and accountability ensure compliance becomes an ingrained hygiene culture.
Documentation: The EHO's Proof (Management of Safety)
If it isn't documented, the EHO assumes it didn't happen. Documentation is your proof that you are actively managing your food safety hazards.
Pest Control Log:
This is your most vital record. It must contain:
• Contractor Details
• Dates of Visits
• EHO Findings (and PGM findings)
• Corrective Actions Taken by the business (e.g., “Gap under back door sealed on 15/03/2025.”)
• HACCP/FSMS Integration: Show how pest control is integrated into your Food Safety Management System (FSMS), often as a crucial prerequisite program, ensuring compliance with all legal requirements.

Pest Control FAQs for Food Businesses
Which pests should I worry about in my food business?
In a food business, the pests you really need to take seriously are the ones that can contaminate food, spread disease, or affect your hygiene rating.
The main ones to worry about:
Mice
Rats
Cockroaches
Flies (house flies, fruit flies, drain flies)
Stored product insects (e.g. flour moths, beetles, weevils)
Ants
Birds (especially pigeons and gulls)
Wasps
The “highest risk” group (the ones inspectors focus on most):
Rodents (mice and rats)
Cockroaches
Flies
Stored product insects
Those are the ones most likely to cause a hygiene rating drop because they directly indicate contamination risks in food handling or storage areas.
How do I stop pests from getting into my restaurant?
Stopping pests from getting into a restaurant is really about building strong barriers + habits so they never get the chance to settle in. In practice, it’s a mix of prevention, exclusion, and good day-to-day hygiene.
1. Seal up entry points (exclusion)
2. Control food sources (this is the big one)
3. Waste management
4. Keep kitchens dry and clean
5. Block common pest highways
6. Staff routines and monitoring
7. Professional pest control (IPM approach)
Which parts of my kitchen attract pests the most?
The main parts of a kitchen that attract pests are areas where they can easily find food, water, warmth, and shelter.
In practice, that’s usually:
Bin and waste storage areas (inside and outside)
Drains and sink/wash-up zones
Food storage areas (especially dry stores and packaging stores)
Under and behind equipment (ovens, fridges, prep units)
Delivery and back doors/loading bays
Greasy or hard-to-clean surfaces and corners
Staff areas where food or drinks are left out
If you keep those areas clean, dry, and well-sealed, you remove most of what pests are actually looking for.
What should I do if I find pests in my restaurant?
If you find pests in your restaurant, the key is to act quickly, calmly, and in a way that shows you’ve contained the risk and are preventing it from spreading.
First, remove access to food immediately in the affected area. Cover or discard any exposed food and clean down all nearby surfaces so there’s no contamination left behind.
Next, identify the type of pest and how widespread it is. One or two sightings might indicate an entry issue, while droppings, nests, or repeated sightings suggest an active infestation.
Then, contain the area as best you can. Stop using that section for food preparation if needed, and prevent staff or customers from coming into contact with it.
After that, carry out a deep clean, focusing on floors, corners, equipment bases, and hidden areas where pests tend to travel or nest. Normal cleaning usually isn’t enough at this stage.
You should also check and block potential entry points right away—doors left open, gaps around pipes, damaged seals, or overflowing waste areas often explain how they got in.
Finally, contact a professional pest control contractor and record everything you’ve found and done. This is important for food safety compliance and your hygiene rating, especially if inspectors visit.
What are the risks if my restaurant fails an inspection?
If your restaurant fails an inspection, you risk:
A low public food hygiene rating
Loss of customer trust and reduced trade
Enforcement action (improvement notices or restrictions)
Possible temporary closure in serious cases
Fines or legal action if issues are severe
Costly clean-up, pest control, and re-inspections
In short, it can affect your reputation, income, and ability to stay open.
