Male bats, due to the cooler temperature, prefer its single, narrow, bottomless chamber. The bat condo has four chambers, and appeals more to female bats and their young, who prefer a higher temperature environment. The condo will house between 30 and 50 bats. It also is bottomless. The bat mansion has five chambers and an attic, which will house up to 150 bats.
Bats can move up and down inside the house to the most comfortable temperature.
Other plans for making bat houses are also available. Whatever plans you choose, it is important to use rough- cut lumber and turn the rough sides inward. The grooves on the inside help bats to climb and roost. Place the bat house near a water source, or provide one that is protected from cats. Hang the house 12-15 feet above ground on a pole in an area that gets seven hours of sun.
