Effective Methods to Prevent Bats from Re-entering Attics

Have you ever wondered how to keep bats from returning to your attic? These nocturnal creatures can cause havoc in your home, damaging property and posing health risks. Fortunately, there are proven methods to prevent bats from re-entering attics, ensuring a safe and bat-free environment. In this article, we will explore some effective techniques that wildlife control professionals use to solve this common problem.

Sealing Entry Points

The first step in preventing bats from re-entering your attic is to identify and seal all potential entry points. Bats can squeeze through tiny gaps as small as 3/8th of an inch, making it essential to thoroughly inspect your home for any openings. Common entry points include gaps in roof lines, loose tiles, uncapped chimneys, and gaps around vents and windows.

Once identified, these entry points should be sealed using appropriate materials such as caulk, steel wool, or hardware cloth. It is essential to ensure that all gaps are completely sealed, as bats can easily find and exploit even the smallest openings. Remember, a thorough inspection and sealing of all potential entry points is the foundation of any successful bat prevention strategy.

Installing Bat Exclusion Devices

Bat exclusion devices are an effective and humane way to prevent bats from re-entering your attic. These devices allow bats to exit your home but prevent them from returning. A commonly used exclusion device is the bat cone or funnel. It is installed over the entry points, allowing bats to fly out freely but not re-enter due to the shape and size of the cone.

It is crucial to install exclusion devices during the right time of year, typically in late summer or early fall, when bats are more likely to be out foraging for food. Installing exclusion devices during the maternity season, when bats have young pups, is not recommended as it can separate mothers from their offspring.

Using One-Way Doors

Similar to exclusion devices, one-way doors provide a simple and effective solution to prevent bats from returning to your attic. These devices, typically made of netting or mesh, allow bats to leave but not re-enter. One-way doors are installed over entry points, ensuring that bats can find alternative roosting sites while preventing them from coming back into your attic.

It is important to monitor the one-way doors regularly to ensure that all bats have left and to promptly seal the entry points after their departure. This method is highly effective, but it requires careful monitoring to ensure its success.

Attic Vent Screening

Attic vents are often overlooked as potential entry points for bats. These vents provide excellent access for bats seeking shelter in your attic. To prevent them from entering, it is crucial to screen all attic vents with appropriate materials such as hardware cloth or mesh. This will allow proper airflow while keeping bats out.

Additionally, it is important to inspect and maintain attic vents regularly, ensuring they are in good condition and free of any damage or gaps that could allow bats to enter. Regular maintenance of attic vents is essential in maintaining a bat-free attic.

Why Hire a Professional?

While these methods may seem simple enough, it is highly recommended to hire a professional wildlife control expert to handle bat prevention and removal. Professional wildlife control technicians have the knowledge, experience, and specialized equipment to effectively and safely exclude bats from your attic.

Attempting to handle bat removal on your own can lead to potential health risks, as bats can carry diseases such as rabies. Furthermore, mishandling exclusion devices or sealing entry points incorrectly can result in bats becoming trapped inside your home, causing even more problems.

By hiring a professional, you can ensure that the job is done correctly and efficiently, protecting your home and family from the risks associated with bat infestations. Professionals also offer additional services such as cleanup and decontamination, ensuring that your attic is safe and bat-free.

In conclusion, preventing bats from re-entering attics requires a combination of sealing entry points, installing exclusion devices or one-way doors, and screening attic vents. While these methods can be implemented by homeowners, it is highly recommended to hire a professional wildlife control expert for effective and safe bat prevention and removal.
