Advice to help you do this action

The following optional advice may help you to do this action. Your agreement document will set out all the activities you must do.

About grey squirrels

Grey squirrels are non-native invasive species found mainly in woodland settings. They damage trees by stripping the bark. They also threaten the native red squirrel population by:

out-competing them for food

spreading the squirrel pox virus

Use the non-native species secretariat (NNSS) information portal to identify grey squirrels. Red squirrels are a protected species, so make sure you identify the correct species.

Your species management plan will give details of the management actions you’ve agreed with your Natural England adviser or Forestry Commission woodland officer.

Forest Research has information on controlling grey squirrels in forests and woodlands in the UK .

Manage by trapping

You can manage grey squirrels effectively by trapping them. You can:

trap in early spring (usually from March to April) and again in the summer (usually June and July) if there is still evidence of grey squirrel causing damage

use a live capture trap where red squirrels or pine martens are present or suspected – if you know red squirrels and pine martens are not present, you may use an approved spring trap

locate all traps and any associated tunnels in suitable habitat and minimise the risk of capturing non-target species

bait the traps for 5 days before they are set – if bait is taken in this period, you can set the trap (if you use whole maize as bait, a squirrel will only eat the germ and discard the kernel, whereas a mouse will chew the whole kernel)

move the trap to a more suitable location if bait is not taken after 5 days

Shooting at bait stations

You can shoot grey squirrels as part of a management programme but unplanned incidental or occasional shooting does not count as part of your management effort.

Use multiple bait stations as part of the management programme. Visit each bait station multiple times a week with each visit lasting several hours. Trail cameras can help to monitor bait stations to understand when it’s best to visit.

Management by drey poking

Drey poking is acceptable as a supporting management method to assist with shooting. Drey poking is particularly effective at times of year when grey squirrels are less active, but it is not suitable as a sole management strategy. Drey poking must not be used in areas where red squirrel or pine marten are found as they may be occupying the dreys.

Shooting at dreys is not suitable as a management method. It is unlikely to be effective, as they are too dense for pellets to penetrate and may be occupied by non-target species.

Free shooting of individual squirrels is not a suitable management strategy as it is unlikely to be effective.

When to carry out management

It’s best to carry out grey squirrel management for tree protection in March or April. You can repeat in June or July if there’s still evidence of damage.

For red squirrel conservation, you can carry out surveillance and grey squirrel management all year round, but it’s most effective when the least amount of natural food is available.

How to dispatch trapped squirrels

Use cranial concussion or an airgun to dispatch any grey squirrels caught in a live trap. If you cannot use an airgun on site, you may also use an approved spring trap attached to the cage trap.

Anyone who intends to trap grey squirrels will need appropriate training.

Dispose of grey squirrel carcasses responsibly once dispatched, for example, by incineration or burial (you may not be able to do this some locations, such as SSSIs ). Ensure you have all the necessary permissions before undertaking this work.

Trap inspection and maintenance

Check traps at least once a day. You may need to check them more frequently after severe weather events to make sure they’re working correctly. Check:

any tethers for damage

any stakes and knots are secure

no debris has entered the trap

the trap monitoring unit (if using) and trap door for damage

You can log each inspection in your species management plan.

Have regard to legislation and good practice relevant to the actions you carry out, such as the Animal Welfare Act 2006.

To check which spring traps are legal for capturing grey squirrels, check:

the Spring Traps Approval (England) Order 2018

the Spring Traps Approval (Variation) (England) Order 2021
