Pest Control RAMS Guide for UK Contractors

Key Topics in a Pest Control RAMS

Pesticide COSHH and application certification

Pesticides used in UK pest control are regulated under the Control of Pesticides Regulations 1986 (as amended) and the Plant Protection Products Regulations 2011. Only approved pesticide products may be used, and application must be carried out by a certified operative — typically a BASIS PROMPT or City & Guilds 2395 (Safe Use of Pesticides) qualified technician for general pest control, with specialist certificates required for specific applications (rodenticide bait management, fumigation, aerial application). The RAMS must list every pesticide product to be used (including active ingredient, concentration, and formulation), reference the Safety Data Sheet and label, confirm the certification held by each operative, and specify the control measures for each product: application rates, restricted areas, PPE, pre-entry intervals, and residue management.

Tamper-resistant bait stations and non-target species protection

Rodenticide bait must be placed in tamper-resistant bait stations to prevent access by non-target species (pets, wildlife, children) under the UK Rodenticide Stewardship Scheme. The RAMS must describe the bait station type, placement locations (mapped on a site plan), the inspection frequency (minimum every 14 days for active infestations), the record format for bait uptake and replenishment, and the secure storage and disposal procedure for unused or expired bait. Secondary poisoning of birds of prey and other wildlife from rodenticide bait is a known environmental risk — the RAMS must confirm that second-generation anticoagulant rodenticides (SGARs) are only used as a last resort under the stewardship restrictions, with a signed rodenticide stewardship assessment.

Confined space and void access for pest work

Pest control frequently requires access to roof voids, floor voids, sub-floor spaces, drainage chambers, and service ducts — many of which meet the definition of a confined space under the Confined Spaces Regulations 1997. Before entry, the RAMS must require: atmospheric testing for oxygen deficiency (particularly in drainage chambers where biological activity consumes oxygen), toxic gases (methane, hydrogen sulphide), and flammable vapours; a confined space entry permit for any space meeting the regulatory definition; a standby person at the entry point with means of raising the alarm; and a rescue plan. Pest control in roof voids of pre-2000 buildings also requires an asbestos awareness check before entry, as roof insulation, pipe lagging, and roof boards may contain ACMs.

Fumigation and gas treatment controls

Fumigation using phosphine, methyl bromide, or carbon dioxide requires specialist competence and planning beyond standard pest control RAMS. Gas fumigation in the UK must be carried out by a licensed and certified fumigator, with formal notification to the HSE (for certain fumigants), full evacuation and sealing of the building or structure, atmospheric monitoring before re-entry, and a written re-entry clearance certificate signed by the fumigator-in-charge. The RAMS for fumigation must describe the fumigant to be used, the targeted pest species, the application concentration and exposure period, the sealing methodology, the monitoring equipment and re-entry threshold, and the emergency response procedure if a gas leak occurs during or after treatment.
