How to Seal Entry Points to Stop Squirrel Infestations for Good

February 26, 2026

Squirrels may look cute when they’re running through your yard, but once they find their way into your attic or walls, they can cause serious trouble. From chewing through wires and insulation to nesting in your home’s structure, squirrels are persistent invaders that won’t leave on their own. The best way to keep them out for good? Seal every possible entry point before they move in.

Here’s how professionals—and homeowners—can protect a home from squirrel invasions effectively.

1. Inspect Your Home Thoroughly

Start with a full inspection of your roofline, vents, soffits, and attic spaces. Squirrels only need a hole about the size of a baseball to squeeze through. Look for gnaw marks, torn shingles, or loose siding—these are signs that squirrels may already be trying to enter.

2. Identify and Seal Gaps

Common squirrel entry points include:

• Roof edges and fascia boards
• Chimney caps and vents
• Gaps around pipes and cables
• Attic vents and eaves

Seal these areas using heavy-gauge metal mesh, steel wool, or sheet metal, which squirrels can’t chew through. Avoid using foam or soft materials—they’ll make quick work of those.

3. Repair Structural Damage

If squirrels have already caused damage, it’s important to repair and reinforce those areas. Replace broken soffits, tighten loose boards, and ensure your chimney cap is secure. A strong structure keeps wildlife out and protects your home from future nesting attempts.

4. Trim Trees and Remove Access Points

Squirrels are excellent climbers. Keep tree branches trimmed at least 6–8 feet away from your roof, and remove overhanging limbs that act like “bridges.” This simple step greatly reduces their access.

5. Don’t Forget the Follow-Up

Even after sealing entry points, continued inspection is key. Squirrels are persistent, and they’ll look for other weak spots. Regular maintenance helps ensure your home stays wildlife-free year-round.
