RALEIGH, N.C. — The N.C. Wildlife Resources Commission (NCWRC) urges homeowners to inspect attics and chimneys for bats now, before pup-rearing season, when their hunger for insects is at a high, begins on May 1.

"Their hunger for insects peaks during pup-rearing season, which runs May 1 to July 31 across North Carolina," according to the NCWRC. "Early spring is the perfect time to check for bats and make sure if any are getting into the building, they end up elsewhere before this season’s pups are born."

Bats provide natural pest control by consuming large amounts of insects, but evicting them during their pup-rearing season is illegal in North Carolina, according to the NCWRC. Newborn bats cannot fly and they rely on their mothers for survival. Removing adult bats during this time leaves pups to starve and may cause mothers to enter homes searching for them.

“Evicting bats during this time ensures any pups in the roost will starve [and] to make matters worse, desperate mother bats may fly through open doors or windows trying to reach their pups, increasing the chance of a close encounter with humans,” said Katherine Etchison, NCWRC’s bat biologist. "By August 1, bat pups are old enough to fly, so it’s safe to evict bats after that date.”

To check for bats, look for small, rice-sized droppings beneath vents, shutters, or entry points. If bats are present, hire a licensed Wildlife Control Agent or follow Bat Conservation International’s eviction guidelines before May 1. Between May and July, homeowners can seal entry points to keep bats out of living spaces but should wait to evict them until later.

If a bat is found inside, especially if it may have had contact with a person or pet, contact the county health department immediately.

Since bats return to the same roosts each year, permanent repairs are key to keeping them out. Installing a bat box in a sunny spot can provide an alternative roosting site.
