Preventing squirrels from entering lofts and roof spaces
Grey squirrels only need a small opening to enter a roof space. Common access points include gaps around fascias, soffits, eaves, roof edges, vents and damaged roofline materials.
Once a squirrel has found a suitable entry point, it may continue to use the same route and other squirrels may follow. Closing the access point is usually the most important step in preventing the problem from returning.
Squirrel-proofing from inside the loft
Where a safe internal loft hatch is available, we can often identify the entry point from inside the roof space. Daylight, draughts, staining, droppings, gnaw marks or disturbed insulation can help locate the access route.
Internal proofing may involve sealing the entry point with suitable mesh or other rodent-resistant materials, depending on the structure and access available.
External proofing at the roofline
In some cases, the entry point cannot be reached safely from inside the loft. External proofing may then be required around the fascia, soffits, eaves or roofline. This may need ladder access, tower access or a roofer, depending on the height and condition of the building.
Proofing should normally take place after squirrel activity has been brought under control. Blocking an active entry point too early can trap a squirrel inside the roof space and may cause further damage as it tries to escape.

Squirrel control FAQs
We first assess the roof space, likely entry points and level of squirrel activity. Where trapping is appropriate, we place approved squirrel traps in suitable locations and check them in line with welfare requirements.
Grey squirrels cannot legally be released back into the wild once deliberately captured, so control must be carried out carefully, humanely and in line with relevant legislation.
Once activity has been brought under control, we normally recommend proofing the access points to help stop further squirrels entering the loft or roof space.
Yes. Grey squirrels can be removed from attics and lofts, but the method depends on the roof space, access points, level of activity and any risks before deciding on the most suitable approach.
Where live-capture trapping is used, traps must be monitored regularly and any captured grey squirrel must be handled lawfully and humanely. Once squirrels are removed, the entry points should be inspected and proofed where possible.
After the activity has been brought under control, proofing helps reduce the risk of more squirrels entering the same roof space.
No. We do not treat red squirrels. Red squirrels and their places of shelter are protected by law, so they must not be trapped, poisoned, killed, injured or disturbed.
Most squirrel problems in London involve grey squirrels. If there is any uncertainty about the species, this should be confirmed before any control work begins.
