What to look for
Bats don't wander into your South Bend, IN attic by accident — they're returning to a warm, dark roost, and they come back to the same one year after year. Across South Bend, bats are in their maternity season from late spring through summer (roughly May through August), when females raise pups in roosts, and they enter through gaps as small as 3/8 inch. Across South Bend, the real problem isn't the bat you see at dusk; it's the roost it's returning to and the gap it found.
