Finding Flying Squirrels on Roofs Nocturnal and rarely seen by humans, flying squirrels build nests in t rees and have loose flaps of skin on their arms that allow them to soar through the air. Their unique abilities grant them easy access to roofs and chimneys. Besides that distinctive feature, they resemble typical small squirrels with brown fur and white undersides. Since the pests are then able to break into attics, flying squirrels on the roof often cause issues for homeowners. Problems and Damage Once flying squirrels get into attics, they make clawing and gnawing sounds throughout the night. This destroys wooden support beams, copper wiring, and insulation. Not only is this damage expensive to repair, but electrical fires can occur when frayed wires go unnoticed. Furthermore, the presence of flying squirrels on the roof attracts mites and additional unwanted pests. Prevention and Removal Given their special ability to gain access to roofs and attics, flying squirrel infestations are hard to prevent. However, homeowners can do things like trim tree branches that hang over houses and make sure all vents are sealed to reduce the possibility of finding the pests inside. Individuals who encounter flying squirrels on the roof should contact the licensed specialists at Critter Control, as they are well-versed in the removal of these problematic pests.
