The western pipstrelle is commonly the first bat out in the evening and the last bat to be seen after sunrise,being most active in the hours immediately following sunset and preceding sunrise and are usually not active during the overnight hours. These bats  feed on insects, and have great flight maneuverability in order to chase them.
During the day, rock crevices serve as the preferred roosting sites for P. hesperus, although sometimes they can be found roosting in crevices inside mines. They may also be found in buildings.
