You can control grey squirrels in the UK, but you need to stick to some pretty strict rules. Don’t harm or kill red squirrels under any circumstances—they’re protected. If you’re thinking of taking action, make sure you’re following the law and only use humane, approved methods, or you risk fines or even criminal charges.
Let’s get into what the law actually says, when you’re allowed to act on your land, and which methods meet both legal and welfare standards.
You’ll also find out how to tell if you’re dealing with a protected red squirrel, when you need permission, and what safer options you might want to try before thinking about lethal action.
Legal Status of Killing Squirrels in the UK
You can control grey squirrels in a lot of situations, but red squirrels have strong legal protection.
Laws treat each species differently, and you need to follow animal welfare rules and get landowner consent if you’re using lethal methods.
Differences Between Red and Grey Squirrels
The Wildlife and Countryside Act 1981 protects red squirrels. If you intentionally kill, injure, or disturb red squirrels or their dreys, you’re committing an offence.
Don’t use any method that could harm red squirrels or their shelter.
Grey squirrels, though, are seen as an invasive or pest species in many areas. You can control grey squirrels to stop them damaging property, trees, or native wildlife.
But you have to act humanely and avoid any method that causes unnecessary suffering. The British Association for Shooting and Conservation has some good advice on safe, legal shooting practices—worth a look.
If you know red squirrels live nearby, you need to avoid any control method that could harm them. Check which species are present before you do anything.
It’s actually illegal in many places to release a captured grey squirrel back into the wild.
Relevant Wildlife Laws and Acts
The Wildlife and Countryside Act 1981 gives native species like the red squirrel strong protection. It makes it a crime to intentionally or recklessly kill or disturb them, and covers all of Great Britain, though Northern Ireland has some differences.
The Hunting Act 2004 affects certain hunting methods, but doesn’t actually ban humane pest control of grey squirrels. The Animal Welfare Act 2006 means you can’t cause unnecessary suffering when handling or dispatching wild mammals.
That law covers trapping, shooting, or any other control method.
Before you start, check both national and local regulations. Scotland and Northern Ireland have some extra rules or amendments that might affect what you can do.
Licensing, Permissions, and Landowner Consent
You usually don’t need a specific licence to control grey squirrels on your own land or land you have permission to manage. Don’t trespass, though.
You need the landowner’s consent if you want to enter private land, use traps, or shoot on someone else’s property.
Sometimes, you might need a licence—like if your control work could affect protected species or if you’re doing something on a bigger scale. Local conservation bodies or government agencies might issue licences for things like preventing serious damage or disease.
If you’re not sure, ask the relevant statutory body before you start.
Stick to best-practice guidance, use humane methods, and keep clear records of what you do. If you’re using firearms, follow the law and safety rules—organisations like the British Association for Shooting and Conservation have guidance on this.
Humane and Legal Methods for Controlling Grey Squirrels
Sometimes, you need to reduce grey squirrel numbers to protect timber, red squirrels, or your own property. Use legal methods, stick to welfare rules, and don’t move animals to new areas.
Permitted Killing and Trapping Techniques
You can kill or trap grey squirrels on most private land without a licence, but you have to use humane methods.
Common legal options include live-capture cage traps and spring traps—but only where red squirrels aren’t around. If you’re using a gun, most people recommend an airgun, and only if you know what you’re doing.
Always check traps at least once a day. Don’t use poisons or drowning—those aren’t allowed.
If you’re on a Site of Special Scientific Interest (SSSI) or other protected land, check with the conservation agency first before killing or removing animals.

Animal Welfare Requirements
You need to prevent unnecessary suffering under the Animal Welfare Act 2006. Act quickly if you trap an animal, and use a dispatch method that kills fast and cleanly.
If you’re not sure how to do it humanely, get a trained contractor to help.
Wear gloves and follow hygiene steps to lower the risk of disease. Always check that the animal is dead, every time.
Keep records of your control work—dates, locations, methods. That’s not just for your own sake; it helps if you ever need to prove you followed welfare standards.
Use disinfectant when trapping near red squirrel populations to avoid spreading disease.
If you trap a non-target species, release it right away and make sure it’s unharmed.
Trapping, Snares, and Release Rules
You can use live capture traps and spring traps. But self-locking snares? Those are usually illegal for most pest control, and the rules around them are pretty strict.
If you’re even thinking about using snares, double-check your local laws and guidance. Getting it wrong can land you in trouble for breaking animal welfare rules.
Caught a grey squirrel? Don’t even think about letting it go. Releasing captive grey squirrels is actually an offence, plus it can spread diseases and hurt other wildlife.
If the law allows, you can leave carcasses where you found them, or just get rid of them as your local rules say.
If there are red squirrels nearby—or you even suspect there might be—stick to live-capture traps only. Make sure you check and disinfect those traps regularly.
Never use kill traps or poison if red squirrels could get caught in the crossfire.
