The removal of bats should always be done by a professional because if they are not removed properly, the roost could split into several roosts and begin roosting in other areas of the structure.
Bats are nocturnal and are found roosting in attics, soffits, fascia holes, barns, under barrel-tile roofs, or just about anywhere that stays cool and dark. Bats are usually spotted flying out of homes at dusk and re-entering the house in the early morning.
