It also is illegal to remove them, according to WRAL. There's a law on the books in the state that makes it illegal to remove bats during mating season -- May 1 to July 31, WRAL reported.
Experts say that if bats have moved in, don't worry about it. Bats are usually harmless. But they warn that the animals can carry diseases, specifically rabies, but it's rare, WRAL reported.
"As long as they're not causing you a problem -- like living actively in the structure or flying around scaring your kids -- you just need to let them do bat stuff and eat the bugs until the end of July. They are certainly not evil, and they are good for reducing the mosquito population," Josh Langdon, an exterminator, told WRAL.
