Why Orange County homes get so many squirrels
Squirrels follow the nut trees, and Orange County is covered in them. The oak and hickory forests of the Hudson Highlands, Schunnemunk Mountain, Sterling Forest and Harriman produce big acorn crops in good years, and squirrel numbers jump the following spring. When those populations crash or the next year's crop fails, squirrels go looking for new food and shelter, often in neighborhoods.
Mature street trees do the rest. Old maples and oaks hanging over rooflines in the village of Goshen, Warwick and Cornwall give squirrels a direct bridge to the gutters. In wooded developments around Highland Mills, Central Valley and Monroe, houses sit inside the forest, and squirrels treat them like another tree.
Older housing adds weak points: wood soffits that have rotted, gable vents with flimsy screens and gaps around old chimneys. Newer homes are not off the hook. Vinyl soffit panels pop loose easily, and the open ends of plastic ridge vent are a favorite way in for flying squirrels.
