Many people install bat houses near their homes because the flying mammals help control insect populations. But for some people, having a colony of bats at home can be too bothersome, noisy and messy. If you want to relocate bats, contact your local animal control office and make sure it isn't illegal to move them. If it isn't, find out who they recommend as a professional wildlife control service to come do the job. Summer and fall are the best times to relocate bats because come wintertime, the bats will be hibernating and will die from the cold if relocated.
