Quick Answer: What Should You Do If There Are Rats in the Workplace?
If rats are seen or suspected in the workplace, the issue should be reported, risk assessed and addressed promptly. The responsible person should arrange a professional inspection, restrict access to affected areas where necessary, protect food and staff welfare areas, clean safely, identify entry points, review waste management and implement a documented control plan.
The correct response is not panic — it is a structured workplace pest-management plan. Record the evidence, protect people and products, call a professional, identify the source and document the action taken.
Immediate Steps
- Report the sighting or evidence immediately.
- Record where and when activity was seen.
- Keep staff away from contaminated areas where practical.
- Protect food, stock, packaging and welfare areas.
- Arrange professional pest control.
- Identify entry routes, drains, waste issues and proofing defects.
- Document the action taken.
- Review prevention measures to stop recurrence.
Are Employers Responsible for Rats in the Workplace?
Yes. Employers have duties to protect the health and safety of employees, and workplace pest activity can fall within that duty where it creates a health, hygiene or safety risk.
The Health and Safety at Work etc. Act 1974 is the primary health and safety legislation in Great Britain and requires employers to ensure, so far as reasonably practicable, employee health, safety and welfare at work. The Management of Health and Safety at Work Regulations also require employers to make a suitable and sufficient assessment of risks to employees and others affected by work activities.
General information only: this page is not legal advice. Where there is a serious employment, landlord or enforcement dispute, obtain appropriate professional advice.
Health & Safety at Work etc. Act 1974
Employers must take reasonable steps to protect employee health, safety and welfare. For rats, this may include controlling contamination risks, safe welfare areas, cleaning and professional pest control.
Risk Assessment Duties
A rat issue should be assessed, controlled and reviewed, especially where staff may encounter droppings, urine, damaged stock, contaminated surfaces, wiring damage or food areas.
Prevention of Damage by Pests Act
Local authorities can require action where rats or mice are present. Owners, occupiers, tenants or landlords may have responsibilities depending on the premises and source.
Food Safety & Food Hygiene
For restaurants, cafés, food shops, bakeries, pubs, staff canteens and warehouses, pest control is essential to prevent contamination and hygiene enforcement risk.
Employee Concerns
If a worker believes there is serious and imminent danger, employment protections may become relevant. Staff should report concerns and seek proper advice if there is a dispute.
Landlord / Managing Agent Issues
Lease terms and building responsibility may affect who pays, but action should not be delayed while responsibility is clarified.

What Are the Health Risks of Rats in the Workplace?
Rats can create workplace risks through droppings, urine contamination, damaged materials, gnawed packaging, odour, staff anxiety and customer complaints. In food premises, they can create serious hygiene and enforcement risk.
Workplace rat activity can affect kitchens, stockrooms, staff rooms, basements, bin stores, drains, food storage areas, ceiling voids and service routes.
Common Risks
- Droppings in storage or work areas
- Urine contamination
- Contaminated food or packaging
- Gnawing to stock, cables, pipework or structures
- Odour from hidden activity
- Staff concern or refusal to use affected areas
- Customer complaints and reputational damage
- Repeat infestation if entry points remain open
Signs of Rats in the Workplace
Rats are often detected by evidence before they are seen. A professional inspection looks at the pattern of signs, the location of activity and the likely route between food, shelter and access points.
- Large dark droppings
- Gnaw marks on packaging, timber, doors or pipework
- Greasy smear marks along walls or skirting
- Scratching or thudding noises
- Burrows outside the building
- Damaged stock or food packaging
- Strong musty or ammonia-like smell
- Footprints or tail marks in dusty areas
- Activity near bins or waste areas
- Noises in ceilings, basements, risers or service voids
Where Rats Are Commonly Found in Workplaces
Rats can affect almost any workplace, but risk is higher where food, waste, warmth, shelter or structural access is available. In London, workplace rat activity is often linked to drains, communal waste areas, older buildings, basement spaces, shared service routes and nearby food businesses.
Commercial kitchens Restaurants Offices Warehouses Retail stockrooms Bin stores Basements Plant rooms Staff canteens Loading bays Service yards Ceiling voids Drainage chambers Schools Healthcare settings
Rats in Offices
Office rat problems often begin around kitchens, waste areas, basements, risers, plant rooms or external bin storage. Staff sightings, droppings or noises should be recorded and inspected promptly.
Rats in Restaurants & Food Businesses
Rat activity in a food business is urgent. Dry stores, equipment voids, waste areas, drains, delivery zones and neighbouring premises should be assessed as part of a documented pest-management system.
Rats in Warehouses & Stockrooms
Warehouses and retail units can attract rats through stock, packaging, loading bays, delivery routes, food items, pet food, waste areas and structural gaps.
Schools, Nurseries and Healthcare Settings
Where children, vulnerable people, patients or care users are present, rat activity must be managed with particular care. The response should include restricted access to contaminated areas, safe treatment choices, hygiene advice, proofing and careful documentation.
Who Should Report Rats at Work?
Everyone has a role in reporting signs of rats. Employees should report sightings, droppings, gnaw marks, damaged packaging, smells, noises, burrows, contaminated food or unsafe cleaning situations. Managers should record the report and arrange action.
For food businesses, staff awareness is especially important because early reporting helps prevent contamination and enforcement issues.
Report These Signs
- Rat sightings
- Droppings or urine marks
- Gnawed packaging
- Smells or noises
- Burrows near bins or external walls
- Damaged stock
- Contaminated surfaces
- Possible entry points
What Should Employers Do After a Rat Sighting?
- Record the evidence: date, time, location, who reported it and what was seen.
- Protect people and products: keep staff away from contaminated areas where practical and isolate affected stock.
- Avoid unsafe cleaning: do not dry sweep droppings or disturb heavy contamination without precautions.
- Arrange professional pest control: inspect likely routes, harbourage, food sources and proofing defects.
- Review waste and housekeeping: check bins, food waste, cleaning, stock storage and building maintenance.
- Identify entry points: inspect pipework, doors, vents, drains, basements, service risers and external walls.
- Document action: keep records of inspections, findings, treatments, proofing works and follow-up.
Can Employees Refuse to Work If There Are Rats?
This depends on the circumstances. A single historical sighting is different from active infestation in a food-preparation area, contaminated staff room or unsafe working zone.
Employees should usually report the issue to a manager, use the workplace reporting procedure, speak to a health and safety representative where available, keep records of concerns and avoid disturbing contaminated areas. This page provides general information only and is not legal advice.
Can a Business Be Closed Because of Rats?
Yes, in serious cases, especially where food safety is involved. Local authorities and environmental health officers can take enforcement action where pest activity creates unacceptable risk.
A business is most at risk where there is live activity in food areas, droppings in kitchens or stores, gnawed food packaging, contaminated food-contact surfaces, poor waste management or no evidence of corrective action.
Landlord, Tenant or Employer: Who Is Responsible?
Responsibility depends on the workplace arrangement, lease terms, source of the issue and who controls the affected area. The employer must protect staff and manage immediate workplace risk. The tenant or business operator may be responsible for housekeeping, waste and pest control inside their unit. The landlord or freeholder may be responsible for structural defects, drains, communal areas or external building fabric. The managing agent may be responsible for communal bin stores, plant rooms, risers and shared areas.
Responsibility disputes should not delay action. Rats can spread through buildings quickly, and the immediate risk should be controlled while liability is clarified.
Why Rats Enter Workplaces
Rats enter workplaces for the same reasons they enter homes: food, shelter, warmth, water and access. In London, many workplace rat issues are building-related rather than purely hygiene-related. A clean office can still have rats if there is a drain defect, shared riser or open basement route.
- Poor waste control
- Open bins and food waste
- Gaps under doors
- Pipe gaps and broken airbricks
- Drain defects
- Basement access
- Service risers
- Nearby restaurants or takeaways
- Construction work
- Neighbouring infestation
- Poor proofing after refurbishment
Rat Entry Points in Workplaces
Common workplace entry points include gaps around pipework, open service penetrations, broken airbricks, damaged vents, gaps under fire doors or external doors, drain defects, inspection chambers, loading bay thresholds, poorly sealed roller shutters, basement wall gaps, cable routes, gaps behind kitchen units, old redundant pipework, external wall defects, service risers, ceiling voids and floor voids.
Rats can exploit surprisingly small openings, so proofing must be detailed and completed with suitable materials. Expanding foam alone is not reliable rat proofing.
Why Documentation Matters
Documentation is important for workplace compliance and business protection. For commercial premises, records help show that the business acted responsibly and did not ignore the issue.
Good records may include date and location of sightings, photos, risk assessment notes, pest-control reports, treatment records, monitoring results, proofing recommendations, cleaning records, staff communication and follow-up notes.
Workplace Rat Control Checklist
- Report sightings or evidence immediately.
- Photograph droppings, gnawing, damage or entry points.
- Keep staff away from contaminated areas where practical.
- Protect food, stock and packaging.
- Do not dry sweep droppings.
- Contact a professional pest controller.
- Inspect waste and bin areas.

Emergency Workplace Rat Control in London
Some workplace rat issues require urgent attention, especially where rats are seen in food areas, staff welfare rooms, customer-facing spaces, schools, healthcare premises or commercial kitchens.
Arrange urgent professional help if a rat is seen indoors, droppings are found in a food or staff area, packaging has been gnawed, staff are refusing to use an area, customers have seen rats, or you suspect drainage access.
Preventing Rats in the Workplace
Prevention should be part of every workplace pest-management plan. Food, waste, access, drains and building fabric all need to be managed together.
- Keep bins closed and clean.
- Do not leave food waste exposed.
- Store food in sealed containers.
- Keep dry goods off the floor.
- Clean under equipment and shelving.
- Inspect deliveries for damage.
- Maintain external areas.
- Cut back vegetation near walls.
- Seal pipe gaps and low-level holes.
- Fit suitable door strips.
- Repair damaged airbricks and vents.
- Keep drains and inspection chambers in good condition.
- Train staff to report pest signs.
Why Professional Proofing Is Essential
Rats will return if the entry route remains open. Professional proofing may involve sealing gaps around pipes, repairing wall defects, protecting airbricks, closing door gaps, proofing kitchen voids, sealing redundant pipework, strengthening weak materials, protecting service risers, reviewing drains and installing suitable mesh or metal where appropriate.
Important: expanding foam alone is not reliable rat proofing. Rats can gnaw through weak materials, so proofing must be appropriate for the risk, location and building fabric.
