Protecting Your Attic From Squirrels

Our region is home to tens of thousands of squirrels.  The gray squirrel is the most often seen species for our area. Keeping squirrels out of an attic can be a bit of a challenge, but there are several effective strategies you can use:

1. Seal Entry Points
   – Inspect the Attic: Look for any holes, cracks, or gaps in the attic. Squirrels can squeeze through very small openings.
   – Seal Holes: Use materials like steel mesh, sheet metal, or hardware cloth to cover any holes. Ensure that all vents, chimneys, and gaps around cables or pipes are also sealed.
   – Repair Damage: Fix any broken or missing roof shingles, and replace any rotting wood that might provide access.

2. Use Repellents
   – Smell Repellents: Squirrels dislike certain smells, such as peppermint oil, ammonia, or vinegar. Soak cotton balls in these substances and place them around the attic.
   – Sound Repellents: High-frequency ultrasonic devices can deter squirrels, though their effectiveness can vary.

3. Install Barriers
   – Trim Trees: Trim any tree branches that are close to your house. Squirrels can jump several feet, so it’s best to have at least a 10-foot gap.
   – Install a Squirrel Guard: Place metal collars or squirrel baffles around trees and utility poles to prevent them from climbing.

4. Trapping
   – Live Traps: Use live traps to catch and relocate squirrels. Check local regulations as relocating wildlife can be restricted in some areas.
   – Hire a Professional: If you’re not comfortable trapping and relocating squirrels yourself, consider hiring a wildlife removal professional.

5. Clean Up
   – Remove Food Sources: Ensure there is no food available in or near your attic. This includes securing garbage bins and not leaving pet food outside.
   – Clean the Attic: Remove any nesting materials or food remnants that might attract squirrels.

6. Monitor Regularly
   – Regular Inspections: Periodically check your attic and the exterior of your home for any signs of squirrel activity.
   – Maintenance: Keep up with repairs and check any previously sealed entry points to ensure they remain secure.

Implementing a combination of these strategies will help you keep squirrels out of your attic and prevent the damage they can cause to the exterior and attic space of your home.
