Kansas State University wildlife expert Drew Ricketts typically sees an increase in calls during spring as bats come out of hibernation and remain active through August. Many homeowners begin noticing signs of bats in their homes—often in attics or upper areas. If the bats aren’t in the main living space, Ricketts often recommends leaving them alone, since trying to remove them can be difficult and potentially cause more harm.

Instead, he suggests installing a “bat excluder” or “bat valve” at suspected entry points. These devices, whether homemade or commercially made, allow bats to exit but prevent re-entry. However, timing is critical. Baby bats, or pups, born in April or May can’t fly until at least August. Blocking access too early can separate mothers from their pups, leading to dead bats, odor, and sanitation issues.

Ricketts also warns that some bat species in Kansas are protected, and bats can carry rabies. If bats are found in living spaces, contact a professional and consider rabies testing if exposure is uncertain.
