Large Colony of Bats Can Live in Attics
From May through July, some species of bats such as Mexican Free-Tailed Bats and Big Brown Bats can form a large colony in an attic or other space in your home. These colonies often have a maternal colony in which the female bats leave the babies, or pups, in the area. The bat pups are unable to fly, which can be an issue if an exclusion (placement of the one-way door to evict the bats out of the space) is completed at this time. The adult bats will fly out at night and feed, and if a bat exclusion is done at this time, the adults will not be able to get back into the space, and the pups will then starve and die. It can then cause another issue to the homeowner in the form of a very unpleasant smell.
During the winter months, bats may also go into dormancy (slowing of all body functions during short periods) or hibernation (slowing of all body functions during more extended periods) from January through March. Bat exclusion during this time is complicated, and the exclusion process will take more extended periods or will need to wait until the temperatures reach around 50 degrees. Due to the different seasons of bat behavior, we must consider proper timing for the humane exclusion of the bats. We work with our customers to give the best solution for your nuisance bat issues.
