Bats generally leave their winter roosts for summer sites in April.

A single Big Brown Bat can eat between 3,000 and 7,000 mosquitos in a night, with large populations of bats consuming thousands of tons of potentially. Bat prey includes lacewings, cockroaches, gnats, beetles, moths, and mosquitos. The fungus grows on hibernating bats, irritating and possibly dehydrating them so they wake up. You should also carefully select when to erect your bat box. Bats are the only major predator of night-flying insects, acting as a valuable natural pest control resource. In North America, white-nose syndrome has been associated with the deaths of 5.5 million bats since 2006.The females then store the sperm and do not become pregnant until the spring. Bats mate during the autumn and sometimes into the winter when they hibernate.They often seek out caves and abandoned mines, and will. Pipistrelles are our most common bats, but we don’t know where they all go in winter! We have not found enough hibernation roosts to account for the numbers we see in the summer months. When do bats hibernate In most of North America, bats hibernate from late Fall until early Spring.They often move into underground sites, such as caves. During hibernation, bats need roosts that are cool and remain at a constant temperature.

A bat’s body temperature lowers and their metabolic rate slows, meaning they use less energy and can survive on the fat they have stored up instead of trying to forage for food. Hibernation is an extended period of deep sleep (or torpor) that allows animals to survive cold winters with harsh weather.
