Why would you want to encourage bats to roost in your area? Bats are very beneficial. A single bat can eat up to 600 mosquitoes in one hour. That translates to 3,000 insects in one evening.
North American bats use an amazing technique called echolocation to find their food in the dark of night. Bats also have fairly good eyesight.
Bats hibernate from late October to early April. They do not migrate.
Water is a very important element in your habitat for bats. Bats naturally forage along streams, creeks, rivers, and over ponds.
Place a bat box 16 feet from the ground facing a very open area. Make sure it can hold at least 100 bats for best results.
