How to keep bats away from your home

Bats are wonderful creatures. They are a vital part of the ecosystem and can be very beneficial to have around from the perspective of humans. For example, since they are natural predators of bugs, they can help reduce the amount of pesky flying insects around your home! However, having bats around is one thing. Having them in your home is another. How can you prevent bats from taking up residence in your home? Here are four tips to help.


One common entry point for bats is where the roof intersects with other building features such as soffit or fascia . Bats can squeeze through small openings, gaps, or even damaged roofing materials. Start by inspecting your roof thoroughly. Look for any cracks, holes, or loose tiles that may serve as an entry point. However, caution is needed before sealing openings so as not to trap the bats inside. This could just send them right into your living space!

Damaged Exterior

Bats are opportunistic creatures, and a damaged exterior provides them with an open invitation. Inspect the exterior of your home for any cracks, gaps, or holes in the walls, siding, or foundation. Bats can exploit even the smallest openings, so be meticulous in your examination. Again, be careful when sealing off these possible entry points. A good rule of thumb is: if you cannot slide the tip of your pinky finger back and forth in the space, then it hasn’t become big enough for bats to take advantage of and can be safely sealed. Anything bigger than that though could be an active entry point. By maintaining a structurally sound exterior, you create a less inviting environment for bats looking for shelter.

Open Windows and Doors

Leaving windows or doors open is another way bats may find their way into your home. While it may seem like a minor oversight, bats may enter through these openings, especially during the night. Ensure that all windows and doors are securely closed, especially during dusk and dawn when bats are most active.


Vents, such as those in attics or crawl spaces, can become a cozy hideout for bats seeking refuge. Regularly inspect and secure vents using fine mesh screens or covers. Ensure that all openings are adequately sealed.

The Bottom Line

Whether it’s through roofing, damaged exterior, open windows and doors, or vents, taking proactive measures will help safeguard your living space from these winged intruders. Regular maintenance and timely repairs not only protect your home from structural damage but also ensure a bat-free environment for you and your family.
