While being relatively harmless, bats can be a nuisance and cause a disturbance in your home. Not only are they noisy, but they can also interfere with your insulation, so it is important to encourage these creatures to move outside.

Depending on the state where you live, there are slight differences in how to move or remove them from your attic, or elsewhere in your property, and there are a number of ways you can remove bats from your home naturally. Therefore, it is advised that you check your local area laws to ensure you are safe from any legal trouble before proceeding.

If you are experiencing bats in your attic, however, our experts have shared their best methods to send them on their way.

1. Identify entry points

‘The first thing you should do is look for entry points,’ says A.H David, owner of Pest Control Weekly. ‘Bats can enter through small cracks and gaps as small as a half inch big.’

As you would when getting rid of squirrels in the attic, or removing raccoons, look for these sized spaces around your roof and eaves. You may find it easier to locate the entry points at night. As bats are nocturnal, they leave their base at night to feed, so try watching your house from the outside to see where the bats are flying out.

By doing this you will be able to identify the rough area where the bats are entering and leaving your home as well as any other entry points you may not have been aware of.

2. Install bat exclusion devices

According to professional roofer, Chris Stevenson, once you have identified all of the entry points, you can install one-way bat exclusion devices. These devices allow bats to leave your attic but prevent them from returning. Install these on the identified exit points.

There are a variety of different one-way bat exclusion devices available, including these bat cones, available at Amazon, so you can choose one that best suits your needs.

3. Seal up all entry points

After you have installed your bat exclusion devices, wait a few days. This is to ensure that all of the bats have left.

Once you are confident that the bats have all left you will need to remove the exclusion devices and seal up all of the entry points to prevent them from coming back.

This can be done with caulk, at Amazon, or weatherstripping, also at Amazon.

4. Maximize light sources

With bats being nocturnal, they typically do not like areas with a lot of light. You can deter bats from your attic by adding more light sources to the area.

‘Bats are nocturnal animals with a low tolerance for light,’ says Allan Bossel, owner of Michigan Bed Bug Specialists. ‘Use bright lights and loud noises in the attic during the day to encourage bats to leave and find alternative roosts.’

You can achieve this by maximizing natural light sources or by plugging in more lights and lamps into the attic and turning them on during the day.

5. Call a professional

If you are concerned about the laws and regulations when dealing with bats, or if you would just prefer hiring someone, you can always call a professional.

When dealing with a large colony, often there will be young bats. These will be too young to fly during certain months and therefore will affect when you can have them removed.

In these instances, consulting a wildlife professional experienced in humane bat removal, would be a recommended path, to have them relocated.


Can bats stop development?

The presence of bats does not usually prevent development provided adequate measures are taken to avoid disturbance and loss of roosting opportunities (such as bat houses). Depending on the status of a roost, appropriate provisions for bats must be made either in the developed structure or an acceptable alternative structure.

If you have a bat infestation, it is important to locate the entry points and seal all but one. As well as light, bats do not like loud sounds, so try and combine the two and encourage the bats to leave during the day by turning on all the lights in the attic and playing loud music. You can also build an external bat house, so the colony has a nearby place to relocate to.
