Spring Bat Removal:

Spring bat removal should take place before pups are born if possible. During the late spring and summer, pregnant female little brown and big brown bats roost in dark, hot places. This is where they like to give birth and raise their young.

Males, often live in solitary or in groups less than a dozen in the summer. They roost in cooler spots behind window shutters, and awnings and under the bark of trees. Bats rest in these roost sites during the day leaving at sunset to search for food.

Mating takes place in the fall before hibernation and the sperm is then stored in the female’s uterus throughout the winter. The eggs become fertilized when hibernation ends in the spring and in June or early July the females gather into “nursery colonies” and give birth. The gestation period for both the little brown and the big brown bats is 50 to 60 days.

Little brown bats give birth to one offspring and the big brown delivers one or two. As soon as the baby is born it clings to its mother, attaching itself to a nipple and, for the first few days, is carried by her when she flies at night searching for food. At three or four weeks the young begin to take short flights and catch their own food. When the young are able to feed themselves the “nursery colony” disbands to begin preparing for hibernation.
