Facts about grey squirrels
Grey squirrels are not native to Britain - they were introduced to this country from America between 1876 and 1929
Grey squirrels are now common throughout England and Wales
The disappearance of native red squirrels coincided with the arrival of grey squirrels

Opinion differs as to whether grey squirrels were responsible for the disappearance of red squirrels or whether red squirrels disappeared through loss of habitat and disease and grey squirrels simply filled the empty space
Grey squirrels have a grey back and tail with a white belly, their flanks are sometimes reddish. During the summer the coat may appear brown

They are about 45 centimetres long, including 22.5 centimetres tail, and weigh 450-650 grams

They reach maturity at 10-12 months and can have 3-4 litters a year with usually 3 young per litter. Average life span is 2 years
Grey squirrels eat fruits, nuts, cereals, flowers, tree bark and shoots and occasionally feed on bird eggs and insects. They bury surplus food 2-5 centimetres below the soil or in tree hollows in scattered sites

Contrary to popular belief grey squirrels do not hibernate during the winter but they may become less active

Grey squirrel problems
Grey squirrels are most likely to cause problems when they gain access to roof spaces via building defects. Once they have gained access squirrels can cause damage to roof timbers, electrical wiring and plumbing

Grey squirrels are serious pests to forestry plantations where they cause damage by stripping bark from tree trunks. This may also be a problem in parks

Problems can also be caused to gardeners, allotment holders and market gardeners, as grey squirrels will take cereals, fruit and vegetables

Grey squirrels and the law
The Grey Squirrels (Prohibition of Importation and Keeping) Order 1937 makes it an offence to release live-trapped grey squirrels.  The Wild Mammals (Protection) Act 1996 makes it an offence to intentionally inflict unnecessary suffering on any wild mammal
Grey squirrels may be shot but it is an offence to use a firearm close to a highway or near inhabited properties

Approved spring traps (rapid kill) may be used. These must be checked daily and must not be used where domestic or protected animals may gain access to them. Rat/Mice traps must not be used
What you can do
Keep your property in good repair so that a squirrel cannot gain access to the roof space

If a squirrel does gain access to your roof space take action as soon as possible. Enter the roof space from inside the property so that the squirrel exits via the hole. The hole may then be blocked, make sure this is done securely as squirrels can be very determined. Squirrels will normally leave easily but may become protective if they have young
