How to Prevent Wildlife from Getting Into Your Crawl Space and Basement
Wildlife intrusions in crawl spaces and basements are more than just an annoyance—they can lead to property damage, health hazards, and unwanted stress. Preventing wildlife from getting into your crawl space and basement requires proactive measures to protect your home.
Here’s how to prevent wildlife from getting into your crawl space and basement, and around your home.
Seal Entry Points
Even a small hole can be enough for raccoons, rodents, or snakes to slip through. Inspect your home for these vulnerable spots:
- Foundation cracks: Fill gaps and cracks in the foundation with caulk or concrete patching to block entry.
- Vents: Ensure all crawl space vents are covered with metal screens or grates that allow airflow but keep animals out.
- Doors and windows: Use weatherstripping or door sweeps to seal gaps under doors leading to the basement.
- Pipes and wiring holes: Seal around utility pipes, electrical wiring, and other areas that might allow small animals to access them.
Install a Sturdy Crawl Space Door
Many crawl spaces have a door or hatch that leads to the outside. These doors are often flimsy or improperly sealed, making them easy for wildlife to breach. If your crawl space door is weak or damaged, it’s time to upgrade to a sturdy, lockable door that fits tightly against the frame. Choose a material that won’t rot or be chewed through by rodents or other animals, such as metal or treated wood. You should also make sure the door remains latched and secure at all times.
Maintain Proper Drainage and Ventilation
Poor drainage around your home can create wet or damp conditions that attract animals like insects, frogs, and snakes. Ensure your downspouts are directing water away from the foundation, and install a vapor barrier in your crawl space to prevent moisture buildup. Additionally, make sure your crawl space or basement is well-ventilated which helps dry the space so it makes it less attractive to wildlife seeking shelter.
Eliminate Attractants
Wild animals are more likely to enter your home if they’re searching for food, water, or shelter. To minimize attractants:
- Remove food sources: You are more likely to attract raccoons and other wildlife if you store pet food, birdseed, or any food products in your basement or near crawl space doors. Remove them or store them in sealed airtight containers so that your home is less appealing.
- Trim vegetation: Keep bushes, trees, and shrubs trimmed away from your home’s foundation. Overgrown plants can provide a hiding place and make it easier for animals to access your home.
- Reduce water sources: Fix any leaking pipes or faucets and ensure no standing water is around your home’s exterior.
Use Wildlife Barriers and Traps
If you live in an area prone to wildlife issues, consider installing physical barriers such as wire mesh or fencing around the perimeter of your crawl space. A professional pest control company can also set up humane traps to capture and release them safely away from your property. However, avoid attempting to trap animals yourself if you’re unfamiliar with proper techniques, as it can be dangerous.
Regular Inspections and Maintenance
Every few months, check your crawl space and basement for new entry points, signs of animal activity (such as droppings, fur, or nesting materials), or structural issues. Address any problems quickly to stop wildlife from becoming a larger issue. If you detect any intruders, call a pest control professional for help.
