Eastern gray squirrel
Sciurus carolinensis
- Identification
- Familiar gray (sometimes black) tree squirrel; enters attics via roofline gaps and overhanging branches.
- Lifecycle & behavior
- Two breeding seasons (late winter and mid-summer); females den in attics to raise young.
- When it's active in Central NY
- The most common attic invader in CNY, with denning pushes in late winter and again in late summer.
- Risk & damage
- Gnaw wiring (a fire risk), nest in insulation, and chew entry holes; leave droppings requiring cleanup.
- Why DIY falls short
- Removal without sealing invites the next squirrel, and chewing defeats light repairs.
- How we treat it
- Removal timed around denning, chew-resistant sealing of entries, and attic cleanup/restoration as needed.
Gray squirrel or flying squirrel?
The single most useful diagnostic is time of day. Gray squirrels are strictly daytime animals — if you hear activity in the attic in daylight, particularly early morning, that is a gray squirrel. Flying squirrels are nocturnal, so scurrying that starts at dusk and continues through the night is almost certainly flying squirrels.
Sound differs too. Gray squirrels are heavy enough to sound like something walking or rolling; flying squirrels are lighter and faster, often described as skittering. Gray squirrels are also much larger, with a full bushy tail.
Gray squirrels in Central New York
Gray squirrels get into attics and soffits primarily via overhanging limbs, and mature tree canopy touching a roofline is the common denominator on nearly every job. That makes Cayuga Heights, Forest Home, Cornell Heights, and the older tree-lined neighborhoods particularly prone.
There are two entry pushes each year, corresponding to the two breeding periods — late winter into spring, and again in late summer. A female looking for a nest site will chew and enlarge existing gaps at roof edges, gable vents, and soffit corners.
Removal without exclusion is the standard failure. Trapping the animal currently in the attic leaves an open, known entry point, and another squirrel finds it — often within the same year. Sealing the entries and cutting back the limbs that provide access is what actually resolves it.

Eastern gray squirrel — common questions
How do I tell what is in my attic without seeing it?
Note when you hear it. Daytime activity, especially early morning, indicates gray squirrels. Activity that begins at dusk and runs through the night suggests flying squirrels or bats. That single observation narrows it substantially, and with bats it matters legally because exclusion timing is restricted.
We had a squirrel removed and another one came back. Why?
Because the opening is still there. Removal without exclusion leaves an accessible, proven entry point that another squirrel will find, often the same season. Sealing all the entries and trimming back the limbs that give roof access is what makes it stop.
