Signs of Squirrels in Trees Trees that dot the backyards and public spaces of suburban neighborhoods provide essential food and shelter for squirrels. Agile climbers, the pests can be seen and heard scurrying up tree trunks and leaping from branch to branch as they scavenge for nuts and berries. They are also known to chew tree bark, which leaves visible signs of damage. As leaves begin to fall in autumn, squirrel nests, which are comprised of twigs and leaves, can be seen nestled securely in the crook of sturdy, bare branches high off the ground. Problems Their tendency to nest in unoccupied attics is the main reason squirrels are considered pests. Squirrels in trees will eventually try to chew their way through small openings, climb up drain spouts, or leap onto roofs from overhanging tree branches to gain entrance to unoccupied attics. Once inside, they contaminate houses with parasites and excrement, gnaw on electrical wires to create fire hazards, and tear insulation to make nests, resulting in higher home heating and cooling costs. Squirrels are also notorious for damaging backyard bird feeders. Removal Squirrels in trees are difficult to remove for the average homeowner. Residents can reduce the possibility of damage by placing squirrel baffles around trees and bird feeders, but the only surefire way to protect against the nuisances is to contact a professional wildlife removal service such as Critter Control. Our teams of expertly trained personnel can remove squirrels from trees and attics as well as help safeguard homes and yards against future infestations.
