PLACEMENT OF YOUR BAT HOUSE Most North American bats prefer to live within a few hundred yards of water, especially streams, marshes and lakes. Bats also need an area with an abundance of insects for their food source. The best time to mount your Bat House is in the fall or winter. This allows the wood to age and odors dissipate. Mount your Bat Houseon a pole or under the eaves of a house, garage or barn approximately 12-15 feet above the ground facing the South, preferably in an area that receives sunlight during most of the day. MAINTENANCE FREE! Bat houses require no maintenance and should be left in place year round. Do not become discouraged if bats do not immediately occupy your house. It can take up to a year for a bat house to attract a colony. MOUNTING YOUR BAT HOUSE Screw eye hooks into pre-drilled holes. Hang by nail or screw.
