Grey Squirrels

As an animal the Grey Squirrel looks very attractive with its bushy tail and grey chestnut coat.  In park and garden areas people gain much pleasure from seeing this fairly tame animal close up. However grey squirrels are not native to these shores and The North American grey squirrel to give its full name was deliberately introduced to Britain and other parts of Europe during the 19th Century merely as a curiosity to satisfy the Victorian trend for novelty.  Unfortunately, no one had the foresight at the time to see how much of an impact this alien species would have on our own native species of wildlife.

Since then, the adaptable and hardy grey squirrel has thrived in Britain's parks, gardens and woodlands. It has now become widespread throughout the UK and being larger and more aggressive than its smaller and now much rarer cousin the red squirrel, it has placed red squirrel numbers under serious threat. Under British law grey squirrels are deemed to be a pest species and can be controlled by an authorized person using approved measurers.

Damage

The outdoor damage is fairly innocuous to the general public; they damage trees by stripping off the bark, they take fruit from the garden, raid wild birds’ nests for eggs and raid bird tables for nuts. Most of the time we tolerate this damage, for the pleasure of seeing squirrels around the garden. However, when they get into the loft of a house they do a great deal of damage indeed. Squirrels are incredible acrobats and are able to climb up the vertical outside wall of a house by holding on to the pebbledash or to the tiny gaps between bricks and mortar. Once they reach the eaves, they can find their way in through holes left for overflow pipes or loose slates. Once inside they will gnaw wood, pipes, electrical cables and shred insulation. They will also gnaw at any stored valuables in the loft space. In severe cases squirrels will even gnaw through plasterboard and enter upper rooms. Squirrels are not normally dangerous, but a wild one trapped in a loft or cornered will bite very hard indeed.

Breeding

In the wild grey squirrels can survive in parkland, copses, and trees, and build their nests (called dreys,) from twigs, leaves and moss.  However, being increasingly urban in their habits, they will quite happily nest in roof spaces. There are two breeding seasons each year (one in Feb/March and the other in June/July), with 3-7 "kittens" in each litter. Kittens are born with their eyes closed, without teeth and with no hair. After about 7 weeks they look just like small versions of their parents and are ready to leave the drey.

Legal Status

Because squirrels are regarded as pests, it is perfectly legal for householders to employ professionals to remove them. There are very strict laws about how this can be done - mostly to protect other wildlife from accidental harm. Traps must be of a specific type and size. Poison can also be used, but there are legal restrictions on the type of material and how the baits are laid and it is not available in shops for purchase by the general public. You must not use general use rat poison; it is illegal to do so. The job is best left to a professional pest control technician who has access to the proper materials and who has been trained to use them.
