The big brown bat is about 4.5 inches long and has a wingspan of about 12 inches, so is somewhat larger than the little brown bat. It can be found in Canada and in most of the United States, except the southern parts of Florida and Texas. After the little brown bat, these are the most likely to occupy your bat house. They sometimes overwinter in bat houses as far north as New York. These bats feed on a variety of insects, swooping over meadows and pasture land and among trees and streetlights of cities and towns. Big brown bats mate in fall and winter and produce one or two young a year, in late May or early June. Choose carefully where you put up a bat house for they may abandon a roost if the temperature rises above 95 degrees.
