Signs of Their Presence
Don't be surprised if you see black or white squirrels. They're really gray squirrels with a color variation. Keep an eye out for all types of squirrels.
Sounds: Red squirrels are the loudest, with their sometimes birdlike, sometimes scolding, but seemingly endless chatter. Gray and fox squirrels also chatter, and during the mating season, they'll make a chucking bark as they chase each other. You may hear chewing, pattering, scampering, and scratching sounds in the attic, eaves, and walls from early morning throughout the day-unless the resident are flying squirrels, which are nocturnal.
Scat: Oval, smooth, and roughly ¼ inch long, the scat of flying squirrels is often found in distinctive piles.
Nest: Gray, fox, and flying squirrels make leaf nests, usually placed in a tree crotch, that are used summer and fall.
Evidence of their feeding: Mipped twigs of spruce, hemlock, and pine trees; piles of gnawed nuts (acorns) between attic joist or in wall voids.
Building damage: Holes in vents, eaves, soffits, and fascia boards. Claw marks on siding. Tunnels in insulation. Chewed wires.
