Once a squirrel takes residence in your premises, it can be very hard to get rid of it. Once inside, it considers your property as its own and turns it into a nest. Squirrels are particularly stubborn when it comes to their dwellings. They don’t fear scarecrows, flashing lights, and loud noises and are often protective. They can also gnaw cables, insulation, frameworks, and other components of your buildings. Grey squirrels also cause widespread blackouts. As their teeth grow constantly, they need to grind them on hard surfaces. Sometimes they chew on power lines, which can cause a short circuit and knock out power. Sometimes they jump directly on power lines which can as well cause a power shortage. Squirrels can also cause small structural damage to the buildings. Although relatively clean animals (especially when compared to other rodents), they are messy eaters and can scatter food debris around. They also leave teeth and claw marks on walls, furniture, and wooden components.
