About this guide
Professional grey squirrel removal follows a structured sequence: site survey, trap selection and placement, daily checking, humane dispatch of caught animals, clearance confirmation, and proofing advice. This guide covers each stage of the process — what a qualified pest controller does and why, what legal requirements govern the work, and what property owners should expect from a professional service.
Grey squirrel removal is a legally defined activity in the UK. Under Schedule 9 of the Wildlife and Countryside Act 1981 and the Spring Traps Approval Order 2018, the traps that may be used, the frequency of checking, and the mandatory dispatch of caught animals are all specified. A professional pest controller operates within this framework as a matter of routine — but knowing what those obligations are helps property owners understand what they are paying for and what questions to ask when choosing a service provider.
The Initial Site Survey
A professional squirrel removal programme begins with a site survey, not trap placement. The survey identifies the number and likely location of entry points into the building, the extent of activity in the loft or roof void (assessed by torch inspection, fresh dropping distribution, and nesting material location), and the external features — trees, overhanging branches, adjacent structures — that are providing access. This information determines which trap types are most appropriate, where they should be placed, and how many traps are needed to achieve effective coverage.
A survey that skips this stage and begins with trap placement — without confirming how squirrels are entering and where they are most active — will be less effective than one that works from a clear picture of the infestation's structure. Entry points should be identified at survey stage so that proofing materials can be ordered and ready to install as soon as clearance is confirmed.
Always ask whether a pest controller carries professional liability insurance, is BPCA (British Pest Control Association) or BASIS-registered, and uses only approved traps under the Spring Traps Approval Order 2018. These are minimum standards for professional squirrel removal work — not optional extras.
Trap Selection and Placement
Two main trap categories are used in professional grey squirrel removal. Cage traps — live-capture box traps in which squirrels enter to reach bait and a treadle or spring-loaded door closes behind them — are the most flexible option. They can be placed in loft spaces, along fence lines, at the base of trees, and on runs adjacent to known squirrel routes. Caught squirrels must be checked and dispatched within 24 hours.
Spring kill traps — specifically the DOC 250 and Kania 2000, both approved under the Spring Traps Approval Order 2018 — deliver an immediate, humane kill strike. They must be set inside covered wooden tunnel housings to prevent access by non-target species. Spring traps are particularly effective when placed on established runs and in tunnel housings pre-baited for three to five days before setting, which conditions squirrels to approach the housing confidently.
Trap placement follows observed squirrel movement — inside the loft along joist runs near the drey, externally at the base of trees used for roofline access, and on fence lines or garden walls where squirrels habitually travel. The number of traps required depends on the property's layout and the size of the local squirrel population. A multi-animal infestation requires more traps and a longer programme than a single animal that has recently entered the building.
Professional squirrel removal programmes in residential properties typically require 10 to 21 days to achieve confirmed clearance, with daily trap checking throughout. Single-visit or one-week programmes are rarely sufficient for an established infestation with multiple animals.

Daily Checking and Dispatch
Traps must be checked at least once every 24 hours — both a professional obligation and an Animal Welfare Act 2006 requirement. A caught squirrel left in a cage trap without water, shelter, or timely dispatch is a welfare offence regardless of intent. Professional pest controllers build daily checking into the programme from the start, with checks typically carried out early in the morning when squirrel activity is at its highest and fresh catches are most likely.
Caught grey squirrels are dispatched humanely at the point of capture. Methods used by trained pest controllers include cervical dislocation (a rapid mechanical method that results in immediate loss of consciousness and death), or dispatch with an air pistol where a shot can be safely taken. No squirrel caught in a UK pest control programme may be released — not on the property, not in a park, not anywhere. Release is a criminal offence under Schedule 9 of the Wildlife and Countryside Act 1981.
Clearance Confirmation and Proofing
A confirmed clearance requires a minimum of five consecutive days with no trap captures, no fresh droppings, and no audible activity during dawn and dusk periods. A professional pest controller will confirm clearance in writing before advising that proofing work can proceed. Proofing — the installation of heavy-gauge galvanised steel mesh, metal flashing, and replacement of defective fascia or soffit sections — is then carried out over every identified entry point.
Proofing is a distinct phase from removal and should not begin until clearance is confirmed. Sealing entry points while squirrels remain inside creates a welfare offence and will result in trapped animals causing further structural damage as they attempt to break out. A professional service coordinates these phases in the correct order and provides advice on follow-on trades — electricians, roofers, and insulation contractors — as required for the specific damage found at the property.
Frequently Asked Questions
What does a professional squirrel removal service involve?
A professional squirrel removal service begins with a site survey to identify entry points and assess activity, followed by placement of cage traps or approved spring traps in the correct locations. Traps are checked daily, caught squirrels are humanely dispatched on site, and the programme continues until no catches occur for five consecutive days. The pest controller then advises on proofing entry points to prevent re-entry.
How long does squirrel removal take?
Most professional squirrel removal programmes for residential properties take 10 to 21 days to achieve confirmed clearance. Single-animal entry that has been identified early can resolve more quickly; established multi-animal infestations with breeding dreys typically take longer. Confirmed clearance requires five consecutive days of no trap captures and no fresh activity signs before proofing work can proceed.
What happens to squirrels that are caught in traps?
All caught grey squirrels are humanely dispatched on site by the pest controller — typically by cervical dislocation or with an air pistol. Release is not legal. Under Schedule 9 of the Wildlife and Countryside Act 1981, grey squirrels cannot be released into the wild once captured. Releasing a caught squirrel anywhere — including a park or woodland — is a criminal offence, regardless of how far from the original capture site.
How often are squirrel traps checked?
Professional pest controllers check traps at least once every 24 hours, in compliance with Animal Welfare Act 2006 obligations and professional practice standards. Checks are typically carried out early in the morning during peak squirrel activity. Caught animals are dispatched promptly — leaving an animal in a cage trap without water, shelter, or timely dispatch is a welfare offence regardless of the intent of the trap operator.
Can squirrel removal be done in one visit?
Not for an established infestation. A single visit may place traps, but achieving confirmed clearance of a multi-animal infestation requires daily checking over 10 to 21 days. Companies offering one-visit squirrel removal programmes are providing trap placement, not confirmed clearance. Effective professional removal involves a sustained programme with daily checks until five consecutive trap-free days confirm the space is genuinely clear.
What should I look for when choosing a squirrel pest controller?
Choose a pest controller who holds professional liability insurance, is BPCA (British Pest Control Association) or BASIS-registered, uses only approved traps under the Spring Traps Approval Order 2018, checks traps daily, and dispatches all caught squirrels on site. Ask explicitly whether they carry out proofing advice after clearance and whether they can refer you to appropriate trades for electrical inspection and insulation replacement.
Is squirrel removal covered by home insurance?
Some home insurance policies include pest control cover, but coverage for squirrel removal varies considerably between policies and providers. Most standard home insurance policies do not include routine pest control, though some comprehensive policies cover damage caused by pest infestations — including cable damage and insulation replacement. Check your specific policy wording or contact your insurer before assuming coverage is available.
