The best prevention is to make your home less accessible and less attractive to squirrels. Here's a comprehensive guide based on our 15+ years of experience serving Louisville homes.
Keep all tree branches at least 6–8 feet away from your roofline. Squirrels can leap 8–10 feet horizontally, so err on the side of caution. In Louisville, with our massive urban tree canopy, this is the single most impactful thing you can do. Pay special attention to large oaks, maples, and hickories — their branches grow fast and can reach your roof within a single season.
An uncapped chimney is an open invitation. A professional, code-compliant stainless steel chimney cap prevents squirrels, raccoons, birds, and rain from entering. Learn more about squirrels in chimneys.
Walk the perimeter of your home and look up. Common Louisville entry points include:
Use steel mesh or metal flashing for any sealing — never foam, wood, or plastic. Learn about our professional exclusion and repair service.
Squirrels are attracted to easy food sources near your home:
Mothballs, ammonia, strobe lights, ultrasonic devices, and cayenne pepper are commonly recommended online but are almost always ineffective. A squirrel will not abandon a warm, safe nesting site because of a bad smell. Physical exclusion is the only reliable prevention method.
Many vulnerabilities are invisible from the ground. A professional can access your roofline and identify gaps you'd never see. Our squirrel-proofing service includes a comprehensive inspection and sealing of all vulnerable areas before squirrels find them.
The best time to squirrel-proof your home is before baby season hits. In Louisville, that means scheduling prevention work in January (before the February–April nesting season) or July (before the August–September season).
Our squirrel-proofing service finds and seals vulnerabilities before they become infestations. It's far less expensive than dealing with an active problem.
