Finding a dead bat in your home can be frightening, even during spooky season. The United States Department of Interior states that if you find a dead bat, take these steps:

• Contact your state wildlife agency to report the finding

• Photograph the bat safely to help the wildlife agency determine the species

• Use disposable gloves to place the bat into a plastic bag, making sure to spray with disinfectant and close the bag securely 

• Thoroughly clean your hands and any clothing that came into contact with the bat

If you see one dead bat, you might have a large bat infestation that needs to be treated immediately. Call a local pest control company to properly inspect your home for other bats.

It's advisable to avoid using harmful methods to eliminate birds. Poisoning birds is inhumane and can have unintended ecological consequences, affecting other wildlife and pets. Similarly, using firearms or other lethal means poses safety risks and could be illegal in many areas. Sticky substances like adhesives can cause birds to become trapped and injured. Lastly, playing excessively loud or distressing noises can stress birds and humans. Focusing on humane and environmentally responsible strategies is essential when dealing with bird issues.

Maintain sealed entry points, use deterrents like spikes or sonic devices, and keep areas clean to discourage nesting.

This depends on if their needs are being met. They'll likely return night after night if they have access to food, water, and adequate shelter. If this changes, they’ll look for another roosting spot. This is why bright lights and other dissuading factors often work when removing bats from a property.
