Squirrels and squirrel biology
Grey squirrels (Sciurus carolinensis) are not native to the UK. They were introduced from North America in the 19th century and are now considered an invasive pest. They are very common in urban areas and parks were trees are present.
The grey squirrel is highly adaptable, unlike it's native red cousin (Sciurus vulgaris) which requirements of habitat very specific. The decline and the removal of the red squirrel is caused by grey's. The fact that the grey squirrel is a carriers of pox, to which red squirrels succumb, but grey's have an intrinsic resistance is also an important reason to get rid of grey's and implement a control programme.
Red squirrels are protected under the Wildlife and Countryside Act 1981, unlike the grey squirrel which is classed as a non-native invasive pest species. Because of this live-trapped grey squirrels cannot be released!
Grey squirrels build nests made up of branches and leaves high up in trees, called dreys, for protection and for breeding. Litters of approximately 3 young are born after a gestation period of 1.5 months and are leaving the nest in June. A second litter of young grey squirrels is produced which leave the nest late summer. The grey squirrel will be capable of breeding after at the age of 7-12 months and can live up to 10 years in the wild, but the mean life expectancy is 2 years.
Squirrel damage and reasons to remove squirrels
The most significant squirrel damage is caused by typical rodent behavior; gnawing. Once squirrels have found a way in roof spaces they can cause damage to wood and plaster work, damage electrical wiring, causing a potential fire hazard, and strip rock wool insulation from lofts to form a drey (nest).
It is not uncommon for squirrels to drown in cold water storage tanks to contaminate water with a putrefying carcass.
In forestry effective control is vital as they can stip bark from trees causing trees to die or resulting in a malformed trunk and reducing the commercial value of timber. The potential damage caused are all valid incentives to remove squirrels.

Proofing and reducing food supplies (preventing access to bird feeding tables can be a challenge) should always be a priority before lethal control methods are explored. Proofing includes blocking gaps with wire netting. A metal sleeve around saplings can prevent tree damage.
Lethal methods to get rid of squirrels include shooting, trapping and the use of poison. The use of poison for grey squirrel control is tightly regulated (Warfarin Order 1973) and only specially formulated whole grain wheat poison bait containing 0.02% warfarin can be used in a specially designed metal "hopper" to prevent access by non-target species. The use of any other poisons (ie rat/mouse poisons), other than grey squirrel formulations, is strictly illegal. In addition, baiting can only be performed between 15 March and the 15th of August, if poison is used for outdoor tree protection. Poison
The most frequent method used by aardvark pest control technicians in a domestic setting is the use of live cage trapping. We make sure we adhere to Animal Welfare Legislation & the Wildlife and Countryside Act 1981 (i.e. traps have to be checked at least once a day, at intervals of no more than 24 hours and any grey squirrel caught is swiftly and humanely dispatched).
In addition, when certain traps are used, every possible precaution must be performed to prevent killing of non-target species, including the setting of the trap in a natural or artificial tunnel (about 60 cm in length) which is to be checked on a daily basis.
