How to Keep Bats Out of Your Home: Simple and Ethical Methods


Bats are fascinating creatures that play a crucial role in our ecosystem, mainly by controlling insect populations and pollinating plants. However, when they decide to take up residence in our homes, they can cause inconvenience and pose potential health risks due to their droppings and the possibility of transmitting diseases like rabies. Fortunately, there are humane and effective methods to keep bats out of your house without harming them. In this article, we will explore some practical and ethical ways to ensure that bats remain in their natural habitat while we enjoy ours.

1. Understand Why Bats Enter Homes

Before delving into the methods of exclusion, it's essential to understand why bats might be attracted to your home in the first place. Common reasons include seeking shelter, warmth, and a safe place to roost. Bats are often drawn to attics, eaves, and unused chimneys, which resemble natural cave-like environments that bats naturally prefer.

2. Conduct a Home Inspection

To effectively exclude bats, start by thoroughly inspecting your home's exterior and interior. Look for gaps, cracks, and holes that could serve as potential entry points for bats. Pay close attention to areas around the roof, vents, chimneys, and any damaged or loose siding.

3. Seal Entry Points

Once you've identified potential entry points, it's crucial to seal them off properly. Use caulk, weather-stripping, or wire mesh to close gaps and crevices, making sure to leave no openings larger than half an inch. Remember that bats can squeeze through surprisingly small spaces, so attention to detail is vital.

4. Install Bat Houses

Instead of letting bats take refuge in your home, encourage them to establish roosts elsewhere by installing bat houses in your yard or nearby trees. Bat houses provide a safe and attractive alternative for bats to roost, ensuring they remain nearby to assist in insect control while keeping them out of your living space.

5. Use Bat-Friendly Lighting

Bats are sensitive to light, and certain outdoor lighting can attract insects, thereby attracting bats. Opt for motion-activated or low-intensity lighting to minimize insect presence and, consequently, the bat's interest in your property.

6. Prune Trees and Foliage

Trim branches and foliage away from your house, particularly near potential entry points, to discourage bats from approaching. This not only prevents bats from finding easy access to your home but also reduces the likelihood of branches scraping against the house, which can be mistaken for insects.

7. Adopt Noise Deterrents

Bats use echolocation to navigate, so using noise deterrents can discourage them from roosting in specific areas. Consider using devices that emit high-frequency ultrasonic sounds that bats find unpleasant, but that are safe for humans and other animals.

8. Seek Professional Help

If you're unsure of how to handle a bat infestation or if the colony is too large to manage on your own, it's best to seek assistance from a professional wildlife control service. These experts can safely remove the bats and employ exclusion techniques while adhering to ethical practices.


Keeping bats out of your home is not only essential for your comfort but also for the well-being of these valuable creatures. By understanding their behavior and employing humane exclusion methods, we can strike a balance that allows bats to continue their crucial role in the ecosystem while preserving the sanctity of our living spaces. By implementing these simple steps and respecting the importance of bats in our environment, we can coexist peacefully with these nocturnal marvels.
