Throughout the year, bats move to different locations that each serve a distinct purpose. A bat maternity roost is a place where a large group of pregnant females gathers to raise their babies. During the winter, some species use a hibernation roost to bunch together and conserve heat.

When Is Bat Maternity Season?

Bat maternity colonies begin to form in early April. These roosts are frequently near areas prone to insect swarms such as fields, ponds, or neighborhoods. In the late spring or summer, homeowners who see bats leaving an attic or overhang at twilight may need to check for an infestation.

When Do Bats Give Birth?

Female bats give birth to babies in late May or early June. As with most mammals, the newborns are helpless and need their mother's care to survive. A bat maternity colony starts to break up in mid-July as pups leave the roost.

Special Concerns for Bat Control

Since state laws often protect bat maternity roosts, homeowners should to be careful about how they handle removal. Simply covering an entry hole in the attic after adult bats leave can trap the young inside.

Residents who suspect an infestation during bat maternity season may require a professional to determine the right next step. Contact Critter Control for humane exclusion and removal services.
