Introduction
Squirrels may seem like playful neighborhood animals, but when they invade your attic or walls, they can quickly become destructive pests. In Washington, DC, squirrel prevention is essential for maintaining the safety and integrity of your home. From chewing on electrical wires to nesting in insulation, squirrels can cause thousands of dollars in property damage.
In this detailed guide, we explore why squirrels enter homes, what signs to look for, and—most importantly—how to prevent them. With the help of EJ’s Pest Control’s wildlife exclusion services, you can keep your home safe and pest-free.
Why Are Squirrel Preventiona Problem?
Although squirrels typically nest in trees, they often seek warm, dry places—especially during colder months. Attics, crawl spaces, and even chimneys offer perfect shelter and nesting sites.
Here’s what makes squirrels more than just a nuisance:
-
Chewing Damage: Squirrels constantly chew to wear down their teeth. This leads to damage to wires, wooden beams, PVC pipes, and roofing materials.
-
Fire Hazards: Chewed wires can cause short circuits or fires.
-
Noise: Scratching and scampering sounds in your attic—especially at dawn and dusk—can indicate active nesting.
-
Contamination: Squirrel droppings and urine can contaminate insulation and lead to health hazards like leptospirosis or salmonella.

Common Entry Points for Squirrels
Squirrels can squeeze through openings as small as 2 inches. Common entry points include:
-
Roof vents and soffits
-
Gaps between fascia boards
-
Chimneys
-
Roofline intersections
-
Unscreened attic vents
-
Loose or missing shingles
During an inspection, our wildlife control specialists in DC locate all potential access points and seal them using exclusion-grade materials.
How to Squirrel Prevention Infestations
Here are key prevention strategies every homeowner should follow:
1. Trim Tree Branches and Remove Attractants
Squirrels often access roofs by leaping from nearby trees.
-
Trim branches at least 8–10 feet away from your roofline.
-
Remove bird feeders or use squirrel-proof designs.
-
Keep outdoor garbage bins sealed tightly.
2. Seal Entry Points
Perform seasonal inspections of your roof and attic.
-
Seal holes using galvanized steel mesh, metal flashing, or heavy-duty caulk.
-
Install chimney caps and attic vent covers.
If you’re unsure how to safely seal these areas, our team offers custom exclusion services.
3. Use Squirrel Deterrents
Natural repellents or motion-sensing lights may discourage squirrels.
-
Apply capsaicin-based sprays on wires and wood (safe for humans, irritating to squirrels).
-
Use ultrasonic devices for attic deterrence—though effectiveness may vary.
For long-term results, pair deterrents with professional exclusion methods.
4. Install Gutter Guards and Roof Deflectors
Gutters and roof corners provide ideal access points.
-
Install metal guards to block climbing access.
-
Use roof edge flashing to deter chewing.
