Protecting your home from unwanted wildlife is more than just a seasonal chore; it’s a critical part of exterior home maintenance that can save you significant time, money, and stress in the long run. Animals like raccoons, squirrels, rodents, and bats are surprisingly resourceful when it comes to finding their way into small openings around your home. Once inside, they can cause serious damage by chewing wires, nesting in insulation, and leaving behind dangerous droppings.
This guide will walk you through everything you need to know about animal-proofing your home. From recognizing common entry points to selecting the best supplies and tackling the process step by step, you’ll be equipped to keep your home protected year-round.

Why Animal-Proofing is Essential
Sealing your home is about more than just keeping animals out. Here’s why it’s crucial for every homeowner to prioritize wildlife abatement:
☑ Preventing Damage: Rodents and squirrels often chew through electrical wires, increasing the risk of fires. Other animals, like raccoons, rip apart insulation, leaving your home poorly insulated.
☑ Health Risks: Animal droppings and urine carry diseases like hantavirus (from rodents) and histoplasmosis (from bats). These pose serious health risks.
☑ Cost Savings: Repairing damage caused by animals is typically far more expensive than preventing it in the first place.
☑ Peace of Mind: Knowing your home is sealed off and safe from wildlife provides invaluable peace of mind, especially during colder months when animals are more likely to seek shelter indoors.
Types of Exterior Openings to Seal
Before you can begin animal-proofing, it’s essential to know where these critters are most likely to sneak in. Here are some of the most common entry points to look for:
- Gaps in Siding: Loose or damaged siding creates easy access for squirrels and rodents.
- Vents: Dryer vents and attic vents are major entry points for bats and rats.
- Chimneys: Raccoons and birds often make themselves at home in unprotected chimneys.
- Roofline Gaps: Small openings along the roofline can allow easy access to attics.
- Foundation Cracks: Rats and snakes can slip through even the smallest foundation cracks.
- Windows and Doors: Improperly sealed windows and doors can serve as entry points for insects and small rodents.

Best Animal-Proofing Supplies
To protect your home effectively, you’ll need the right tools. Check out stores like Home Depot and Lowe’s, or online retailers like Amazon, for a wide selection of to choose from. Here’s a breakdown of the best animal-proofing supplies and their budgets to get started:
1. Hardware Cloth
- Budget: $10–$30 per roll
- Uses: Covers larger openings like vents, chimneys, and foundation gaps. Its sturdy material deters raccoons and squirrels.
- Tip: Use a fine mesh size (about ¼-inch) to prevent rodents and smaller animals from squeezing through.
2. Expanding Foam
- Budget: $5–$15 per can
- Uses: Fills gaps in siding, rooflines, and around pipe entry points. Foam creates a durable barrier against small pests.
- Tip: For added strength, combine expanding foam with steel wool.
3. Caulk
- Budget: $5–$10 per tube
- Uses: Seals smaller cracks and gaps in windows, doors, and foundation joints. A must-have for precise sealing.
- Tip: Opt for silicone-based caulk in regions with high heat and humidity, like the Southeast.
4. Steel Wool
- Budget: $5–$20 (depending on quantity)
- Uses: Blocks small holes in walls, vents, or pipes where rodents might try to gnaw through.
- Tip: Choose coarse-grade steel wool for the most effective deterrent.
5. Chimney Caps
- Budget: $30–$100+ (excluding installation costs)
- Uses: Covers chimney openings to prevent raccoons, birds, and bats from entering.
- Tip: Look for caps with mesh sides for added ventilation and protection.
6. Vent Covers
- Budget: $10–$40 each
- Uses: Install over dryer vents and attic vents to keep out bats and small rodents.
- Tip: Choose vent covers with UV-resistant materials for durability in all weather conditions.
7. Weatherstripping
- Budget: $5–$20 per roll
- Uses: Seals gaps around doors and windows to prevent entry by insects and small rodents.
- Tip: Replace weatherstripping annually for maximum effectiveness.
Step-by-Step Guide to Sealing Openings
Follow these steps to protect your home with the supplies listed above:
- Inspect Your Home – Walk around your home to identify all potential entry points. Make note of even the smallest cracks or gaps.
- Gather Supplies – Based on your inspection, purchase the necessary materials (hardware cloth, expanding foam, caulk, etc.).
- Prepare the Area – Clean the openings, removing any dirt or debris to ensure proper adhesion.
- Seal Small Openings – Use caulk for tiny gaps and steel wool combined with foam for slightly larger holes.
- Cover Vents and Chimneys – Install vent covers and chimney caps securely according to manufacturer instructions.
- Reinforce Larger Openings – Attach hardware cloth over large gaps or foundation openings. Secure with screws or heavy-duty staples.
- Perform a Final Check – Walk around your home again to ensure no spots were missed.
Additional Tips for Animal Deterrence
Keeping animals away from your home goes beyond sealing openings. Try these additional strategies for comprehensive home protection:
- Reduce Attractions: Remove food sources like pet bowls, garbage, and birdseed from around your home.
- Trim Tree Branches: Cut back branches that hang near your roofline to prevent squirrels and raccoons from gaining access.
- Install Motion Lights: Bright lights can deter nocturnal animals like raccoons and bats.
- Use Repellents: Spray natural repellents around vulnerable areas to discourage animals from coming too close.
When to Call a Professional Wildlife Control Service
While many small openings can be sealed DIY-style, some situations call for expert help. Consider reaching out to a wildlife control service if:
- The infestation has already occurred, requiring animal removal and cleanup.
- You’re dealing with particularly persistent species like raccoons or bats.
- The scope of necessary repairs feels overwhelming or beyond your expertise.
- Certain areas, like high roofs or tight crawl spaces, are unsafe to access on your own.
Professional wildlife abatement services have the expertise to manage these situations safely and effectively.
In Summary
Protecting your home from unwanted animal intrusions is an essential part of maintaining a safe, clean, and comfortable living environment. By using the right supplies, following a step-by-step sealing process, and implementing additional deterrent strategies, you can significantly reduce the risk of wildlife gaining access to your space.
Remember, prevention is always more effective—and cost-efficient—than dealing with an infestation after the fact. However, for cases that are too complex or hazardous to address on your own, don’t hesitate to call in professional wildlife control services. With careful attention and proactive measures, you can keep your home secure and free from unwelcome critters for years to come.
