This bat house is designed to be optimal for attracting bats to roost. IPM of Alaska has consulted leading bat conservation experts, such as Bat Conservation International to select this design and these instructions for Alaska. Increased urbanization and deforestation in Alaska has removed the many hollow trees bats need to raise young. It is this lack of traditional roosting sites that has forced the little brown bats to adapt to roosting in homes all over the Mat-Su Valley and Anchorage.
