Pest Control for Food Businesses: What the Law Requires and What EHOs Check

The fastest way to lose your business

Few things shut a food business down faster than pests. Local authorities have emergency powers to close premises on the spot where there's evidence of infestation, and prosecutions for pest-related hygiene offences are regular news. A single mouse problem, caught late, can mean closure, a collapsed hygiene rating, and a reputation that takes years to rebuild.

Pest control is a core prerequisite programme and a legal duty, and the good news is that it's largely about prevention rather than reaction. Here's what the law requires, how to prevent problems, and what an EHO checks.

What the law requires

Food law requires that you have adequate procedures in place to control pests, and that your premises are designed, maintained, and kept to prevent pest access and harbourage. In practice this means a permanent, ongoing system to keep pests out and to detect and deal with any that get in, not a phone call to a contractor only once you've spotted droppings.

You don't have to have a pest control contract by law, but in practice most food businesses are strongly advised to hold one with a reputable, competent contractor, ideally a member of a recognised body such as the British Pest Control Association. A professional contract provides monitoring, expertise, and the documentation that demonstrates due diligence.

Prevention first: deny them entry, food, and shelter

Effective pest control rests on denying pests the three things they need: a way in, something to eat, and somewhere to live. This is integrated pest management, and it starts long before any bait station.

1. Proofing. Seal gaps around pipes and cables, fit door sweeps and brushes, screen openable windows, and keep external doors closed. Mice need surprisingly little space to enter.
2. Housekeeping. Clean as you go, deal with spills immediately, and don't let food debris accumulate in cracks, under equipment, or behind units, the exact places infestations begin.
3. Storage. Keep food in pest-proof containers, off the floor (around 150mm is recommended) and away from walls, so you can clean behind and spot problems early.
4. Waste management. Keep bins lidded and away from the building, never leave bags beside bins, remove waste from production areas frequently, and don't leave it inside overnight.

Most infestations trace back to a lapse in one of these four. Get them right and you remove the conditions pests need.

Monitoring and detection

You need to actively look for pests, not just wait to notice them. A monitoring system, usually set up and serviced by your contractor, includes bait stations, traps, and insect monitors positioned around your premises, checked on a schedule that reflects your risk. Higher-risk areas like food storage and preparation warrant more frequent checks than low-risk zones.

Staff are part of the system too. Everyone should be able to recognise the signs of pest activity, droppings, gnaw marks, damaged packaging, smear marks, and know to report them immediately. Early detection is the difference between a quick fix and a closure.

Documentation: the part that proves due diligence

When an EHO inspects, your pest control documentation is scrutinised heavily, and missing or out-of-date records suggest poor management even if your premises look fine. Expect the officer to ask for:

• Your pest control contract (if you have one)
• Visit reports from your contractor, with findings, treatments, and recommendations
• Pest monitoring records
• Any risk assessments relating to pests
• Corrective actions taken in response to activity
• Staff pest-awareness training records

A crucial and often-missed point: when your contractor leaves recommendations (proofing a gap, removing a harbourage), you must act on them and record that you did. An auditor who sees the same recommendation repeated across several visit reports with no action taken will mark you down, because it shows the system isn't being managed.

This is exactly the kind of thing that slips through paper systems. Keeping your pest monitoring records, contractor reports, and the corrective actions you've taken in one place, alongside your other compliance, means the recommendations don't get lost and you can show the full picture on demand. FoodSafe holds these records with the rest of your daily compliance so your pest control system is documented and evidenced rather than scattered across contractor paperwork.

What an EHO checks

Beyond your documentation, an officer assesses the physical reality: signs of activity, the condition and proofing of the structure, housekeeping and waste management, and the correct positioning of any equipment (for example, that electric fly killers aren't directly above food prep surfaces and that their tubes are in date). They may also ask staff what they'd do if they spotted a pest.

Stay ahead of it

Pest control is one area where prevention is overwhelmingly cheaper than cure, and where falling behind carries the most severe consequences in all of food safety. Deny pests entry, food, and shelter through proofing, housekeeping, storage, and waste management; monitor actively; act on every recommendation; and document all of it. Do that consistently and pests become a managed, low risk rather than the thing that closes your doors.
