YOUNGSTOWN, Ohio (WKBN) This is the time of year that bats are coming back to roost, and there are ways to make sure they don’t pick your attic or other spots on your house to make their home.

Many bats prefer to roost in hollow trees or spaces under loose bark, but some end up in attics or barns. The same females might even come back to the same location each year to raise their young.

Now is a good time to make sure all points of entry are closed so bats are kept out.

According to the Ohio Division of Wildlife, if a bat has already begun roosting in your attic or barn, it is important to remember that it is illegal to kill bats. A non-lethal exclusion device is the only legal way of removing bats from a man-made structure.

For a site with 15 or more bats, exclusion devices can’t be used during the maternity season (May 16-July 31) to ensure young are not separated from their mothers.

Learn more about non-lethal exclusion devices and other things you can do now to keep bats from roosting in homes and other buildings this summer at the Ohio Division of Wildlife website.
