Squirrels seek shelter that is safe from predators, warm, dry, and provides a stable place to build nests and raise their young. Your attic, crawl space, or wall voids provide the perfect, predator-free environment for them, especially during baby season or cold winters.
Louisville winters average 30–40°F, and your insulated attic is a warm refuge. Squirrels don't hibernate — they stay active year-round — so a warm attic is extremely attractive when temperatures drop. This is why fall and winter are our busiest seasons.
In the wild, squirrels face threats from hawks, owls, cats, and snakes. Your attic has none of these. It's the safest possible nesting location a squirrel can find — quiet, enclosed, and above ground level.
Female squirrels are especially motivated to find shelter during baby season (February–April and August–September). They need a safe, warm space to raise their young for 8–10 weeks before the babies are mobile enough to leave.
Louisville's massive urban tree canopy means most homes have branches within jumping distance of the roof. Squirrels can squeeze through a hole the size of a quarter — and they can easily enlarge a smaller gap by chewing.
Aging soffits, rusted vents, rotting fascia, uncapped chimneys, and construction gaps are common in Louisville's older housing stock. Squirrels don't create these vulnerabilities — they find and exploit them. Learn about our exclusion and repair service.
The best defense combines two strategies:
Our squirrel-proofing service addresses both — and it's far cheaper than dealing with an active infestation.
Don't try to block the hole yourself — you could trap babies inside. Contact us for safe, humane, professional removal.
