Bats can be beneficial for the environment, but having them inside your home is a different story. They can carry diseases, create messes, and cause structural damage. If you want to keep bats out of your house, follow these five effective methods to bat-proof your home.
1. Seal Entry Points
Bats can squeeze through openings as small as ⅜ of an inch. Inspect your home’s exterior for any cracks, gaps, or holes—especially around vents, chimneys, rooflines, and siding. Use caulk, weatherstripping, or mesh screens to seal these entry points and prevent bats from getting inside.
2. Install Bat Exclusion Devices
If bats have already entered your attic or walls, a bat exclusion device is the best way to remove them safely. These one-way exit tubes allow bats to leave but prevent them from coming back in. After all bats have exited, seal up the openings to keep them from returning.
3. Use Bright Lights and Airflow
Bats prefer dark, undisturbed spaces, so keeping areas well-lit can make them less inviting. Motion-activated floodlights near entry points can deter bats from roosting. Additionally, using fans in attics or enclosed spaces makes the environment less comfortable for bats, encouraging them to find shelter elsewhere.
4. Eliminate Outdoor Food Sources
Bats are attracted to areas with abundant food sources, such as insects and fruit trees. Reduce their food supply by turning off unnecessary outdoor lights that attract bugs, keeping your yard well-maintained, and covering trash bins. You can also install bat houses away from your home to provide an alternative habitat for them.
5. Hire a Professional for Safe Removal
If you suspect a bat infestation, contact a licensed wildlife removal expert. Bats are protected in many areas, and improper removal can be illegal. Professionals can safely and humanely remove bats while ensuring they don’t return.
Final Thoughts
Preventing bats from entering your home requires a combination of sealing entry points, deterring roosting, and eliminating attractants. By taking these steps, you can keep your home bat-free while still allowing bats to thrive in their natural environment.
