Squirrels belong to the most successful and widespread order in the world, rodents. One of the main differences between squirrels and most other rodents is that squirrels have a rather large, bushy tail. All rodents are gnawing animals. Squirrels have well-developed jaw muscles and chisel-like front teeth that can chew through just about anything. These front teeth are kept sharp by gnawing on hard objects such as woody plant materials, seeds and nuts.
Damaged Loft Insulation
When squirrels enter a loft space, they can cause structural damage by tearing up loft insulation for bedding, chewing timbers, pipework and stored items, posing a fire hazard by stripping insulation from electrical wiring. They may also be noisy, and if they drown in uncovered water storage tanks, may contaminate the water supply. For these reasons, it is important to keep squirrels out of lofts.
Rodents are known for their high reproductive rate. Squirrels usually produce 2 litters of 2-4 young each year. The first litter is born in January or February while the second arrives in mid-summer. Young squirrels mature rather slowly for a rodent and are on their own in about 2 1/2 months. Squirrels give birth in nests normally located in trees but this can happen in lofts.
