Pest Control in Food Businesses: EHO Requirements, HACCP Interaction, Monitoring Programme and Documentation

Summary

Pest control in food businesses sits at the intersection of pest management and food safety law. Unlike domestic or commercial non-food settings, where pest control is primarily a COSHH and biocide compliance matter, in food businesses it also engages the Food Safety Act 1990, the Food Hygiene Regulations 2006, and the broader framework of EU-retained food law (now domestically operative post-Brexit). The Food Standards Agency (FSA) inspects food businesses and scores them under the Food Hygiene Rating Scheme (FHRS) — a visible public score that directly affects consumer confidence and trade.

EHOs carry significant enforcement powers. Under the Food Safety Act 1990, an authorised officer can issue a Hygiene Improvement Notice requiring specific remedial actions within a set timescale, a Hygiene Emergency Prohibition Notice shutting premises immediately where there is imminent risk to health, or can initiate prosecution. Evidence of a pest infestation — rodent droppings, gnaw marks, insect frass, live insects — found during an inspection will trigger immediate enforcement action. The presence of pest control documentation (monitoring logs, service records, corrective action reports) is a significant mitigating factor.

HACCP is the legal requirement for food businesses to systematically identify hazards and control them. Pest control appears in HACCP as a Prerequisite Programme (PRP) — a foundational condition that must be in place before the formal HACCP analysis is conducted. Without a functioning pest control PRP, the entire HACCP system is considered compromised. For pest control contractors servicing food businesses, understanding HACCP terminology and being able to provide documentation in a HACCP-compatible format is increasingly a contractual requirement and a professional differentiator.

Key Facts

• Food Hygiene Regulations 2006 (SI 2006/14) — Implement Regulation (EC) 852/2004; require food businesses to have and maintain food safety management systems based on HACCP principles
• Food Safety Act 1990 — Primary UK food safety statute; EHO powers to inspect, issue notices, and prosecute derive largely from this Act
• Hygiene Improvement Notice — Issued where a legal requirement is not being met; specifies the breach and a compliance deadline (minimum 14 days)
• Hygiene Emergency Prohibition Notice — Immediate closure power; applied where there is imminent risk of injury to health; must be confirmed by a magistrate within 3 days
• FHRS scores — Food Hygiene Rating Scheme: 0 (urgent improvement necessary) to 5 (very good); must be displayed by law in Wales and Northern Ireland, strongly encouraged in England
• HACCP prerequisite programmes (PRPs) — Include: pest control, cleaning and disinfection, waste management, personnel hygiene, maintenance. Must be documented and verified
• Service frequency — Minimum monthly visits for high-risk food businesses; some contracts specify fortnightly or weekly for very high-risk operations (e.g., grain mills, chocolate factories)
• Fly control — Insect light traps (ILTs) required in food preparation areas; glue board ILTs preferred over electric grid (which scatters insect fragments); checked and serviced regularly
• Rodent monitoring — Bait stations and/or break-back traps at all external entry points; numbered and mapped; checked at every service visit
• Documentation requirements — Service reports signed and dated; pest activity log; corrective action log; site map showing device placements; trend analysis
• Corrective action — Any pest sightings must trigger documented corrective action: investigation of cause, immediate treatment, structural repair recommendation, and follow-up verification
• Non-chemical monitoring — EHOs increasingly expect evidence of monitoring (traps, ILTs, monitoring records) even in the absence of an active infestation
• Pharaoh ants — Specific risk in hospitals and food businesses; do NOT use residual sprays (scatters colony into multiple satellite colonies); bait programmes only
• Stored product insects (SPIs) — Flour moths, grain weevils, biscuit beetles; require dedicated pheromone trap monitoring; stock rotation and FIFO are PRPs
• Cockroach monitoring — Sticky traps in all harbourage areas; monitored at each service visit; index calculations to measure population trends

What EHOs Expect to See

An EHO visiting a food business will look for evidence of a functioning pest control system, not just a pest control contract. The distinction matters. Having a contract with a reputable pest control company is necessary but not sufficient — the contract must be actively managed by the business and the resulting documentation must be in order.

Specifically, an EHO will expect:

1. A current contract with a named pest control provider, including scope of services
2. A site map showing the location of all monitoring and treatment devices (bait stations, ILTs, traps), with each device numbered
3. Service reports for every visit, signed by the pest controller and the site contact, showing date, time, findings, and any corrective action recommended
4. A pest activity log — a record of all pest sightings by staff between contractor visits (date, location, pest, action taken)
5. Corrective action records — documenting how each incident was investigated and resolved
6. Evidence of management review — that the business owner or manager has reviewed pest control records and acted on recommendations

If proofing deficiencies were identified in previous reports and have not been rectified, this will be treated more seriously than if they are newly discovered. EHOs track whether recommendations are acted upon.

Integrating Pest Control with HACCP

HACCP operates through a seven-step process defined in Codex Alimentarius: hazard analysis, critical control point identification, critical limits, monitoring, corrective action, verification, and record-keeping. Pest control fits into this as a Prerequisite Programme (PRP), which is a foundational hygiene condition that must be in place for the HACCP system to function.

The practical integration looks like this:

Hazard analysis: During the initial HACCP hazard analysis, biological hazards from pests (Salmonella from rodents, Listeria from cockroaches, contamination from insect fragments) should be explicitly listed and referenced to the pest control PRP as the control measure.

Critical limits: While pest control does not usually define a CCP with a numerical critical limit, the PRP should specify the standard (e.g., "no evidence of active rodent infestation"; "ILT catch numbers below 10 flies per week in food preparation area").

Monitoring: The pest monitoring programme (bait stations, ILTs, sticky traps) generates the monitoring data. Service reports are the primary record.

Corrective action: The corrective action procedure must specify what happens when the standard is exceeded — e.g., "any rodent activity triggers immediate cessation of affected production, deep clean, and emergency pest control visit within 24 hours."

Verification: The food business manager should regularly review pest control records — at minimum during the HACCP review cycle (annually or when there is a significant change).

Fly Control — Insect Light Traps (ILTs)

ILTs are the standard tool for flying insect monitoring and control in food businesses. Two main types:

Glue board ILTs: Insects are attracted by UV light and adhere to a replaceable glue board. Preferred in food production areas because no insect fragments are dispersed. Bulbs must be replaced annually — UV output diminishes well before visible light fails, reducing effectiveness.

Electric grid (electrocuter) ILTs: Insects are killed by an electric grid. Not recommended in food preparation or exposed product areas because the electric shock can scatter insect fragments and contaminate food. Suitable for storage areas and external entrances.

Placement is critical. ILTs should be:

• Positioned at eye height (approximately 1.5–2 m from the floor) where insects naturally fly
• Not placed in direct sunlight (competing with UV output)
• Positioned away from food preparation surfaces (risk of fragments from glue-board falling)
• Positioned near entry points (doors, windows, delivery areas) where flies enter

Glue boards should be inspected at every pest control visit; the catch should be recorded and the data used for trend analysis. An increase in fly catch can indicate a nearby development (building work, new waste source) or a change in season, and should trigger a review of control measures.

Rodent Monitoring Programmes

A typical rodent monitoring programme for a food business consists of:

External bait stations: Tamper-resistant stations containing either rodenticide bait or non-toxic monitoring block. Placed at all external entry points, along walls, at drain covers, in delivery yards. Numbered, mapped, and checked at every service visit. If a SGAR rodenticide is used, the CRRU Code requirements apply in full.

Internal monitoring traps: In food production or storage areas, bait stations containing live-catch traps or break-back traps are typically used instead of rodenticide (to avoid risk of rodenticide contamination of food). Traps must be checked frequently — a dead or dying rodent left in a trap is a food safety hazard.

Monitoring blocks: Non-toxic wax or flour-based blocks in bait stations provide evidence of rodent presence without active treatment. Gnaw marks indicate activity; blocks are replaced and the data logged.

Trend analysis: Good pest control contracts include a report analysing bait take or trap catch trends over time. Increasing activity at a particular bait point should prompt investigation before the problem escalates.

Documentation for Compliance

The minimum documentation set for a food business pest control programme:

Records should be maintained in a single, organised pest control file accessible to both staff and inspectors. Digital formats are acceptable and increasingly preferred — cloud-stored records are less likely to be lost in a kitchen environment.

Frequently Asked Questions

What score will my food business get if an EHO finds evidence of pests?

Under the FHRS, the Hygiene procedures element is scored separately from Structural compliance and Confidence in management. Active pest evidence will score poorly in all three areas — it indicates a hygiene failure, a structural deficiency (if entry points are present), and a management failure (if monitoring should have detected it earlier). A single serious pest incident can reduce a 5-star rating to a 0 or 1. The FSA FHRS guidance indicates that persistent pest problems are a key driver of scores at the lower end of the scale.

Can a food business manage pest control itself without a professional contractor?

Small low-risk food businesses (e.g., a sole trader selling homemade jams) may in theory manage basic pest monitoring themselves, but for any premises open to the public and preparing food, professional pest control contracts are expected by EHOs. The documentation, competency, and regulatory knowledge required are difficult to maintain without a specialist contractor. Where a business attempts self-management, the pest activity log and corrective action records must be particularly thorough.

What must happen if rodent activity is found in a food preparation area?

Immediate actions: cease production in the affected area, secure and quarantine any product that may have been contaminated, document the finding in the pest activity log, contact the pest control contractor for an emergency visit. The affected area should not reopen for food production until the infestation is under control, the entry route is identified and proofed, and a deep clean and verification has been carried out. All of this should be documented as a corrective action. If product contamination cannot be ruled out, the food business may have an obligation to report to the local authority under the Food Safety Act 1990.

Are there specific requirements for pest control in schools?

Schools serving food are food businesses for the purposes of the Food Hygiene Regulations 2006. The same requirements apply. Additionally, school pest control must comply with Control of Pesticides Regulations requirements regarding use of pesticides in areas frequented by children. Some pesticides are not approved for use in occupied school buildings. Pest control in schools typically requires treatments outside school hours, with appropriate re-entry intervals observed.

How often should a pest control service visit occur?

There is no single legally mandated frequency. EHOs apply a risk-based judgement. High-risk food businesses (restaurants, takeaways, food manufacturers) are typically expected to have monthly visits as a minimum. Very high-risk businesses (grain handling, pet food manufacturing) may require fortnightly or weekly visits. Low-risk businesses (a café with a small kitchen and no storage of raw meat) may comply with quarterly visits if monitoring records are thorough and no activity is detected. Frequency should be reviewed and justified in the pest management plan.
