Preparing for Pup Arrival
Bat mating season occurs in the late summer to early fall. However, the female bats don’t get pregnant right away. Instead, they hold onto the sperm until later, storing it during the winter hibernation months. Bats may find their way into your attic to hibernate. It offers them great protection from the elements and safety from predators while they are fast asleep and defenceless. In the spring, they emerge from slumber and begin looking for food. At this time, the females release the sperm and become pregnant. Expectant mothers seek out a roost separated from the non-reproducing females and the males. These are called maternity roosts, and little brown bats and big brown bats commonly form their maternity roosts in buildings.
