How To Keep Bats Out of Your Garage

Wildlife 4

Bats are fascinating creatures, and while they play an essential role in our ecosystem, we usually prefer not to share our living spaces with them. If you’ve found bats roosting in your garage, you’re likely looking for safe, effective, and humane methods to keep them out. This comprehensive guide will walk you through the steps on how to keep bats out of your garage, discuss the importance of bats, and provide long-term strategies to prevent them from returning.


To keep bats out of your garage, first, identify and seal off potential entry points using appropriate materials. Install one-way doors to allow bats to leave but not re-enter. Maintain proper lighting in your garage, use ultrasonic bat repellents, and consider installing bat houses to provide alternative roosting sites. Regularly clean your garage to reduce hiding spots. For severe infestations, consider hiring professional bat removal services. Always use humane methods and consult with local authorities if necessary.

Why Bats Enter Garages

Bats commonly enter garages for a few reasons. They may be attracted to the shelter and roosting opportunities your garage offers, especially during the summer months when they are most active. Garages often have vents, gaps, or cracks that can provide easy access for bats. Additionally, if your garage is home to a variety of insects (a primary food source for many bats), it’s like an open invitation for them.

Potential Dangers of Bats in Your Garage

While bats are generally harmless and prefer to avoid human interaction, they can pose potential health risks and cause property damage. Bats can carry diseases like rabies and their droppings, known as guano, can transmit a fungus that causes a lung infection called histoplasmosis. Their droppings and urine can also cause significant damage to your garage’s structure if not addressed promptly.

Identifying a Bat Problem

Before you can take steps to keep bats out of your garage, you need to confirm their presence. Common signs of bats include droppings, oily streaks around potential entry points, strange noises (like chattering), seeing bats fly around your home during sunrise or sunset, strong pungent odor, and dead bats in or around your garage.

Effective Bat Proofing Techniques

Once you’ve confirmed the presence of bats, it’s time to implement some bat-proofing techniques. Here are some effective methods:

Seal Off Entry Points

Bats can fit through tiny spaces, so it’s crucial to seal off all potential entry points. This can be done using caulk, weatherstripping, or other appropriate materials.

Install One-Way Doors

One-way doors or exclusion devices allow bats to leave but prevent them from re-entering. These are an excellent tool for removing bats already inside your garage.

Maintain Proper Lighting

Bats prefer dark spaces. By ensuring your garage is well-lit, particularly during the evening and night hours, you can discourage bats from roosting in your garage.

Use Bat Repellents

Ultrasonic bat repellent devices can be used indoors and are effective in repelling bats without causing them harm. These devices emit frequencies that interfere with a bat’s echolocation navigation, encouraging them to seek quieter locations.

Install Bat Houses

Installing a bat house on your property provides an alternative roosting site for bats, reducing their desire to roost in your garage.

Cleanliness and Clutter

Bats are attracted to dark, cluttered spaces. Regularly cleaning your garage and removing any unnecessary items can help minimize hiding spots for bats.

Professional Bat Removal Services

If you’re dealing with a severe infestation or feel uncomfortable handling the situation yourself, consider hiring a professional bat removal service. These services typically involve humane exclusion methods, ensuring the bats are removed effectively and safely.

Long-Term Strategies

For long-term prevention, regular inspection of your garage for signs of bat activity is crucial. Address any issues promptly to prevent bats from establishing a roost. Regularly clean your garage and remove food sources to make it less attractive to bats.

Remember, bats are beneficial to the ecosystem and are protected by law in many areas. Always use humane methods to remove them and consult with local authorities if necessary.

In conclusion, while bats in your garage can be a nuisance, it’s a situation that can be managed effectively and humanely. By following the steps outlined in this guide, you can keep your garage bat-free and ensure these fascinating creatures continue to play their crucial role in our ecosystem from a more appropriate distance.

Frequently Asked Questions

What time of the year are bats most active?

Bats are most active during the summer months. This is their breeding season and also the time when their primary food source, insects, are most abundant.

How can I identify bat droppings?

Bat droppings, or guano, are typically small, about the size of a grain of rice, and can be recognized by their dark color and shiny, speckled appearance due to the insect parts they contain. They often pile up beneath the bat’s roosting spot.

How does an ultrasonic bat repellent work?

Ultrasonic bat repellents emit high-frequency sounds that bats find irritating or disorienting. These sounds interfere with the bats’ echolocation, which they use for navigation and finding food, thereby encouraging them to seek quieter locations.

What should I do if I find a bat in my living space, not the garage?

If you find a bat in your living space, don’t panic. It’s important not to harm the bat. Instead, try to isolate the bat in one room by closing doors to other rooms. Open a window or door to the outside, and the bat will likely fly out on its own. If the bat doesn’t leave, it’s best to contact a local bat removal service to handle the situation.

Are all bats protected by law?

While not all bats are protected by law, many species are due to their ecological importance and declining populations. It’s always best to check with local wildlife authorities or a bat removal service to understand the laws in your area before taking any action.
