How to keep squirrels out of your attic

Abell Pest Control

Squirrels may seem cute in the park, but when they invade your attic, they quickly become a destructive nuisance. Their impressive climbing skills and determination make them a formidable pest to keep out. Here’s how squirrels get into attics and what you can do to keep them out.

How Squirrels End Up in Attics

Squirrels are natural acrobats with a knack for climbing and jumping. They can leap from trees, fences, or utility lines straight onto your roof. Once there, they’ll look for entry points like loose shingles, gaps in vents, or even tiny holes in soffits or eaves.

These resourceful rodents can gnaw through wood, siding, and even insulation to make their way inside. Once they’ve settled in, squirrels will build nests using attic insulation, chew through wires, and cause extensive damage. Left unchecked, you could end up with an entire family of squirrels living rent-free in your home.

Tips to Keep Squirrels Out of Your Attic

Trim Trees and Branches

Since squirrels often access roofs by jumping from nearby trees, keep branches trimmed at least 10 feet away from your house. This reduces their launching points and makes it harder for them to reach your roof.

Inspect and Seal Entry Points

Regularly inspect your home’s exterior for any cracks, holes, or loose shingles that squirrels could use as an entryway. Pay special attention to:

  • Rooflines and Eaves: Look for loose tiles, shingles, or damaged soffits.
  • Vents and Chimneys: Install sturdy vent covers and chimney caps to block access.
  • Foundation Gaps: Seal small openings with caulk or expandable foam and cover larger gaps with steel mesh.

Test for Squirrels

If you suspect squirrels are already inside your attic, try this simple test:

  1. Roll up a piece of newspaper.
  2. Place it in any suspected entry hole.
  3. Check back after a few days.

If the newspaper has been moved or shredded, you likely have a squirrel problem. If it’s undisturbed, the squirrels may still be outside—but it’s best to seal the hole just in case.

By staying vigilant and following these prevention tips, you can keep squirrels out of your attic and avoid costly repairs. A little maintenance goes a long way in protecting your home from these persistent and crafty critters.
