Flying Squirrels Are Active Right Now in Connecticut

Most homeowners in Waterbury, Southington, and Cheshire have heard of squirrels — but flying squirrels are a different problem entirely. Unlike their gray and red cousins, flying squirrels are strictly nocturnal and they don't actually fly. They glide — up to 200 feet from tree to tree — which is exactly why most homeowners have no idea they're living above them until the damage is done.

Flying squirrel season in Connecticut runs directly behind bat season. Once temperatures drop in early fall and bat activity slows, flying squirrels start moving in. If you're hearing loud thumping, scurrying, or high-pitched chattering in your attic late at night, flying squirrels should be near the top of your list.

What Flying Squirrels Do to Your Home

The real concern isn't the noise — it's what they leave behind. Flying squirrels produce significantly more feces than bats, and their droppings contaminate insulation fast. Once insulation absorbs waste, it loses R-value, locks in odors, and becomes a health hazard that requires full decontamination and replacement to resolve properly.

Beyond the contamination risk, flying squirrels chew. They target electrical wiring, HVAC components, recess lighting leads, and foam insulation. A colony nesting in your attic over a Connecticut winter can create a legitimate fire hazard that doesn't surface until something shorts out.

Signs You Have Flying Squirrels

The most reliable tip-off is noise — specifically after dark. You might hear loud thumping as they land from a glide, or rapid scurrying through walls and above the ceiling. Rub marks around entry points, contaminated insulation, and small clustered droppings are also reliable indicators. Not sure if it's bats, raccoons, or flying squirrels? A free inspection from ProSource identifies the species on the first visit.

How ProSource Handles Flying Squirrel Removal

ProSource uses a two-part approach: targeted trapping to reduce the population quickly, followed by full exclusion to seal every entry point permanently. Flying squirrels are colonial — if one finds a way in, more will follow — which is why exclusion is non-negotiable. We fabricate aluminum sealing materials on-site, install Ridgeguard along ridgelines where appropriate, and warranty every entry point we close. If your insulation has been contaminated, we assess the damage during the inspection and walk you through decontamination and replacement at the same time.

ProSource serves Waterbury, Naugatuck, Cheshire, Southington, Wolcott, Watertown, Plymouth, Bristol, and surrounding communities throughout New Haven and Litchfield County. Schedule your free inspection today — most jobs are booked within 24 hours.
