Grey squirrel live trap: do not release it in the UK
Updated: 17 October 2026
A grey squirrel live trap is not a catch-and-release tool. If you deliberately catch a grey squirrel, you must not drive it to a wood, release it elsewhere or keep it as a workaround. You need a lawful, humane outcome planned before the door is armed. If you are not competent and prepared to provide one, do not set the cage. Several products in our [live trap comparison](/hub/traps/live-trap) mention squirrels while saying little about what follows a catch. A humane title and a large cage do not remove that responsibility. A qualifying purchase can earn a commission at no extra cost to you.

What the law allows after the door shuts
GOV.UK guidance says it is an offence to keep or release a grey squirrel caught on your property and that a live-caught animal must be killed humanely. The England and Wales invasive-species guidance also lists grey squirrel among species that must not be released into the environment. Northern Ireland has its own Wildlife Order provisions, while Scottish rules should be checked with the relevant national authority. Do not take an England-and-Wales page as the complete wording for every UK nation.
Transporting the cage to a distant wood does not solve the problem. It moves an invasive non-native animal and leaves you with the same release prohibition at the destination. Keeping the squirrel indefinitely is not a lawful alternative.
Drowning is not an acceptable shortcut. BASC’s grey-squirrel guidance expressly rules it out, and this page does not provide dispatch instructions. Humane dispatch requires a competent person and an appropriate lawful method. If that is not a responsibility you can meet, engage a competent pest controller before trapping rather than after an animal is confined.
There is a narrower distinction for accidental restraint. RSPCA guidance explains that a grey squirrel accidentally stuck in a bird feeder or trapped inside a building may be freed. That situation differs from deliberately setting a baited squirrel cage. BASC says live-capture traps should be checked at least daily, and more often where red squirrels might be caught.
Red squirrels and pine martens change the risk
Red squirrels are protected, and a cage set where they occur can catch the wrong species. BASC says a non-target red squirrel must be released immediately, while the deliberately caught grey squirrel must not be released. If you cannot distinguish the species confidently, do not set a squirrel trap.
Location matters as much as appearance. GOV.UK tree-protection guidance calls for single-capture ground cages where red squirrels or pine martens are present or suspected, rather than spring traps that could injure a protected non-target. Local records and land-manager advice should be checked before control begins, especially in or near red-squirrel range.
Pine martens are protected and must not become collateral damage in grey-squirrel control. A strong animal can also create a handling risk if caught in an unsuitable cage. Stop, keep people and pets away, and obtain specialist advice if a non-target protected animal is confined. Because the release decision must be made correctly under pressure, identification and professional backup belong in the plan before you arm the door.
Which cages even mention squirrels
The Ratkil listing includes squirrels in its target line, and one UK review describes use for a loft squirrel. Its details omit dimensions, its rating is 3.6 from 1,202 reviews, and review notes include a plate that may need a heavier step. A broad target list cannot substitute for measured internal space or a lawful end plan.
The Thealyn is a wildlife-sized cage at 105 x 31 x 40 cm with two doors. Its bullets add cats and foxes, while the details include squirrels. UK reviews describe unclear instructions and doors that rely on a flat surface. A 3.6 average from 382 reviews is a reason to examine those faults rather than assuming size guarantees secure capture.
The 78 cm Tcowoy also names squirrels and claims a folding galvanised-steel body with a handle guard. Its 5.0 rating comes from just two ratings. The dimensions may place it in the right class, but the evidence is too thin to establish dependable trigger performance. Kwaiyole’s extra-large 32.5 cm cage mentions squirrels, yet that body is much smaller than the wildlife cages. The other Kwaiyole listing says squirrels can bend the mesh, and both Anyhall listings warn that large squirrels may chew wire or break the trigger. None of this is a recommendation to begin squirrel trapping. The humane live trap buying guide explains dimensions. If your intention is relocation, no cage in this comparison is suitable, because the planned action is the problem.
A decision before buying
First confirm that the damage is actually caused by a grey squirrel. A glimpse, noise in a loft or a damaged feeder may not be enough, and trapping can expose birds, hedgehogs, red squirrels or pine martens. Use a competent professional when identification is uncertain or when protected species may occur.
Second, decide who will inspect the trap and who is competent to deal with a grey squirrel lawfully and humanely. Do not buy first and assume a rescue group or pest controller will take over after the catch. If no lawful endpoint is in place, use exclusion or professional control advice instead of live capture.
Third, if trapping is appropriate, choose a single-capture cage with adequate dimensions, strong mesh, a reliable door and safe handling. Test it on flat ground and schedule inspections before arming it. The how to set a live trap guide covers placement and check routines. It does not change the no-release rule. Protect feeders and remove accessible food, and arrange building repairs only after confirming that no animal or dependent young will be sealed inside.
Common questions
Can I release a grey squirrel in a wood?
No. A grey squirrel deliberately caught in a live trap must not be released or kept. Driving it elsewhere only moves the prohibited release to a new location and adds transport stress. If you cannot arrange competent, lawful and humane dispatch, do not set the trap.
What if a grey squirrel is stuck in a bird feeder?
RSPCA guidance distinguishes accidental restraint in a feeder or building from deliberate capture in a baited cage. An accidentally trapped, uninjured animal may be freed where appropriate. Get advice if it is injured, and do not use this exception as a planned relocation method.
Is drowning a trapped grey squirrel allowed?
No. BASC guidance specifically says drowning is not a humane method. This guide does not provide dispatch instructions. Contact a competent pest controller before trapping if you are not trained and prepared to provide a lawful, immediate outcome.
Which cage here is large enough for a squirrel?
The 78 cm Tcowoy and 105 cm Thealyn are wildlife-sized listings that mention squirrels. Ratkil also names squirrels but omits dimensions, while smaller Kwaiyole and Anyhall pages include mesh-damage warnings. Size alone does not establish trigger reliability, welfare or legal suitability.
What if red squirrels live nearby?
Do not set casually. Red squirrels are protected and must be released if caught as a non-target. Guidance calls for suitable single-capture cages where red squirrels or pine martens are present or suspected. Seek local specialist advice and be certain you can identify the catch.
How often should I inspect a squirrel cage?
BASC says at least daily and more often where red squirrels might be caught. Conditions, injury risk or visible distress can require earlier action. Plan and record checks before setting, and never deploy more cages than you can inspect and deal with promptly.
Are the rules identical across all four UK nations?
The no-release principle applies to grey-squirrel control, but the cited statutes and official pages are not worded identically across England, Wales, Scotland and Northern Ireland. Check the relevant national authority or use a competent local professional rather than applying one nation’s citation everywhere.
