Build single board bat houses to celebrate !
Bat houses should be hung at least 10 feet, and preferably 15 feet above the ground. A warm east wall near vegetation and a water source is best for bats making the house their home. On an east wall, they'll receive morning sun and will also be shielded from the hot afternoon sun. Bat houses can also be placed on a pole, tree, or the side of a barn. The exact size and shape of the bat house is not that important except for the width of the opening which should not exceed one inch and ideally is only 3/4 of an inch. No chemically treated wood should be used to construct bat houses. Some lumber is treated with wood preservatives or insecticides which could be harmful to the bats. All inner surfaces of bat houses, regardless of the kind built, must be rough or horizontally grooved so the bats can get a firm foothold. If the wood is planed, you may wish to cut 1/16" horizontal grooves into the surface of the smooth side of each roosting partition at about ½-inch intervals. Any planed surface of wood on the roof, front, back and sides should be turned to the outside of the box. Once the house is up, if you're lucky, you may have bats within a few weeks, especially if the house is up in early spring.
