Before you look for ways to exterminate them, be aware that killing a bat is illegal in many states. They are a protected species, and they actually offer a great deal of value to nature. Many bats help pollinate flowers and spread seeds. A bat can consume its weight in insects, including unwanted pests like mosquitoes. 

Knowing the benefits of bats, you may even be tempted to just let them stay. This, however, can cause health risks for you and your family. 

Bats can be carriers of rabies. If you are bitten by one, you could become infected. Rabies can cause debilitating health issues for many years. Additionally, bat guano and urine can carry a fungal disease called histoplasmosis. In its mild form, this disease can seem just like the flu. However, in more serious cases, it can cause shortness of breath and even respiratory failure. 

If bats have taken up residence in your space for an extended period of time, the guano will have to be safely removed, including any insulation or other materials that have been compromised. The area will need to be professionally cleaned and disinfected.

DIY Methods 

You’ve done an internet search and read that repellents, strobe lights, music, mothballs and ammonia are effective ways to extract bats from your home. These do not work. The only way to safely remove bats from your building is through exclusion. 


Exclusion is performed by attaching nets or tubes over the openings of the bats’ entry and exit points. These are attached in a way that allows bats to exit the structure but prevents them from entering again. 

Along with this, all other holes should be caulked, and screens should be installed over attic vents. Because bats only need ¼-inch of space to get in, compromised space should be left open. If you need a professional to provide a consultation and perform this work, contact us today

Bats are creatures of habit, so they will return every morning to nest again. Although they may appear ominous, we understand they have value for humans and the Earth. If you want to keep the bats in your area, install a bat house near the old opening. They will nest there during the day and continue to eat insects and pollinate at night. 

Once bats are excluded and all entry points have been taken care of, it’s important to remove bat guano and urine. Not only are they potentially detrimental to the health of people who live in the house, bat guano and urine also act as a calling card to other bats.

When to Exclude

Because bats are a protected species, exclusion has to be done at very specific times of the year when maternity season for them is over. Maternity season is between mid to late spring and early to mid fall. If you attempt to perform exclusion during the maternity season, you run the risk of starving any mothers or babies who cannot leave the area.
