Wisconsin has seven species of bats, all of which are insectivorous and use echolocation to navigate and capture prey. Four species are known as the cave bats and hibernate in caves and mines throughout the winter. The cave bats are all susceptible to the devastating bat disease white-nose syndrome. The other three are known as tree bats, and these bats migrate south to warmer climates during winter. General Wisconsin bats information
Bats are important consumers for agricultural, forestry and human pest insects. It is estimated that bats in Wisconsin save farmers up to $658 million every year in the form of pest control services.
