Highly adaptable, bats set up roosts in a variety of environments like deserts, woodlands, suburbs, and urban areas. They are found around the world and only avoid extreme climate zones like the polar regions or especially harsh deserts. While bats prefer warm temperatures, they survive in temperate environments by hibernating come winter months. Bats will use barns, attics, caves, tree cavities, and the undersides of bridges to roost and/or overwinter.
