Quick Answer
Squirrels are the most common attic intruder in New York. Both Eastern Gray Squirrels and Red Squirrels enter attics through gaps in soffits, fascia, and roof vents. Signs include: scratching and running noises during the day, chewed entry holes (3-4 inches), droppings in the attic, and nesting material. Squirrels cause damage by chewing wires, tearing insulation, and leaving droppings. Removal involves one-way exclusion doors and sealing entry points.
New York Squirrels in Attic Guide
Squirrels in the attic are a common problem for New York homeowners. The Eastern Gray Squirrel is the most common culprit. They are active during the day, so if you hear scratching in your attic during daylight hours, squirrels are the likely cause.
