Squirrels may seem like cute, harmless creatures, but when they start chewing on your house, they can become a real problem. Squirrels chew on a variety of materials, including wood, wires, and insulation, potentially causing serious damage to your home. Understanding why squirrels chew and taking proactive steps to deter them is essential to preventing costly repairs and keeping your house intact. Here’s how to stop squirrels from chewing on your house.

1. Identify the Chewing Locations

The first step in addressing a squirrel chewing problem is to identify where the squirrels are causing damage. Look for signs of chewing around the following areas:

• Eaves and Roof: Squirrels often chew on the edges of roofs, shingles, and eaves as they attempt to find a way into your attic or to build a nest.
• Siding and Wood Trim: Squirrels are known to chew on wooden surfaces, especially if the wood is soft or has a moisture issue.
• Wires and Cables: Squirrels will sometimes chew on electrical wires or cables, which can be hazardous and cause electrical damage.
• Vent Covers and Gaps: If squirrels find small openings or gaps in your home’s exterior, they will often chew at them to enlarge the entryway.

Once you've identified the areas being chewed, you can begin addressing the problem effectively.

2. Seal All Entry Points

Squirrels are persistent when it comes to finding ways inside your home. If they’re chewing on parts of your house, they may be trying to enter your attic or other areas for shelter. The best way to stop squirrels from chewing on your house is to seal up all entry points.

• Inspect the Roof and Attic: Check for any gaps, holes, or damaged areas in the roof, eaves, and attic. Pay close attention to vent openings, soffits, and chimneys. Seal small holes with caulk or wire mesh, and use durable materials like steel or sheet metal for larger gaps.
• Close Gaps Around Windows and Doors: Ensure that all windows and doors are properly sealed. Even small gaps can provide an entryway for squirrels. Use weatherstripping or foam sealant to close any gaps.
• Check for Gaps in the Foundation: Squirrels can fit through surprisingly small spaces, so inspect your home’s foundation for any cracks or holes that may be accessible.

3. Install Squirrel-Proof Barriers

To prevent squirrels from chewing through your house’s exterior, consider installing physical barriers that deter them.

• Metal Flashing: If squirrels are chewing on wooden trim or eaves, installing metal flashing around these areas can effectively prevent further damage. Metal is difficult for squirrels to chew through and will protect your home from gnawing.
• Wire Mesh: Use wire mesh or hardware cloth to cover vents, chimneys, and any other small openings where squirrels may enter. Make sure the mesh is securely attached and there are no gaps for the squirrels to squeeze through.
• PVC Pipe: If squirrels are climbing up poles or structures near your house, you can wrap PVC pipe around them. The smooth surface makes it difficult for squirrels to climb.

4. Use Repellents

Squirrels dislike certain smells and tastes, and there are several commercial repellents available to keep them away from your home.

• Pepper-Based Repellents: Squirrels are known to avoid hot or spicy substances. You can apply cayenne pepper, red pepper flakes, or pepper-based sprays around areas they are chewing. These substances will irritate their noses and mouths, discouraging them from continuing to chew.
• Garlic and Peppermint Oil: A mixture of garlic and peppermint oil is another natural repellent for squirrels. Combine the oils with water and spray them on areas where squirrels are chewing.
• Predator Urine: Squirrels are prey to animals like hawks, foxes, and coyotes. Using predator urine (available at garden stores) around areas they frequent can make your home smell like a predator’s territory, causing squirrels to avoid it.

5. Use Squirrel Traps

If squirrels are persistent and chewing on your house, it might be necessary to catch and relocate them.

• Live Traps: Live traps can be baited with food like peanut butter, sunflower seeds, or fruit. Place the traps in areas where the squirrels are most active. Once captured, relocate the squirrel at least 10 miles away to prevent it from returning.

Ensure that you check local laws and regulations regarding trapping and relocating wildlife in your area, as some locations require permits or have specific rules.

6. Use Motion-Activated Deterrents

Squirrels are sensitive to movement and loud noises, and there are several deterrents that use motion detection to startle them.

• Motion-Activated Sprinklers: These sprinklers will spray water whenever a squirrel comes near. Most squirrels dislike getting wet, so this method can be highly effective in keeping them off your house.
• Ultrasonic Repellents: Ultrasonic devices emit high-frequency sounds that are unpleasant for squirrels, but inaudible to humans. Placing these devices around the exterior of your house can help deter squirrels from approaching.

7. Keep Your Yard and Property Tidy

A cluttered yard can attract squirrels and make it easier for them to find food sources and shelter. To reduce the likelihood of squirrels chewing on your house, keep your yard tidy and free of potential attractants.

• Remove Food Sources: Don’t leave pet food, birdseed, or trash outdoors. Squirrels are drawn to food sources, so cleaning up your yard will make it less inviting.
• Trim Trees and Bushes: Squirrels can jump from trees onto your roof or other areas of your house. Keep tree branches trimmed at least 10 feet from your roof and other structures.
• Secure Garbage: Make sure garbage cans are tightly sealed, as squirrels will often rummage through trash to find food.

8. Call a Professional Exterminator or Wildlife Control Specialist

If you’ve tried all of these methods and squirrels continue to chew on your house, it may be time to call in the professionals. A wildlife control expert can help assess your home and recommend more specific solutions to deal with the squirrel infestation.

Conclusion

Squirrels may be cute and entertaining to watch, but when they start chewing on your house, they can cause significant damage. By sealing entry points, installing deterrents, and keeping your property clean, you can prevent squirrels from chewing on your home and keep your house safe from their destructive behavior. If the problem persists, don’t hesitate to contact a professional to help you resolve the issue. With the right approach, you can effectively stop squirrels from causing any more damage to your house.
