Little Brown Myotis
Myotis lucifugus

The Little Brown Myotis is vulnerable to a fungus infection, white-nose syndrome, that is killing bats at an alarming rate in eastern North America and is rapidly spreading west.This typical Little Brown Myotis is a small furry animal about the length of a human finger and the weight of a large coin. Bats take flight at dusk to feed upon a variety of insects that are captured on the wing. In summer, female bats give birth to a single young (rarely twins) in nursery colonies that may contain dozens or hundreds of individuals. Colonies occupy tree cavities, caves, rock crevices, outbuildings, and attics. Young bats nurse for several weeks prior to venturing out to prey upon insects.In fall, bats move to special hibernation habitats that are humid enough to prevent dehydration and cool enough to conserve energy. It is during this period they are most vulnerable to disturbance and to disease.

More Information

Bat conservation by homeowners involves protecting known bat roosts, preserving trees and snags as habitat, protecting natural caves, erecting bat houses, avoiding the use of pesticides, keeping cats indoors, and safely managing attic colonies (see below). Bats navigate in darkness via echoes of their calls, which can be made audible to humans through hand-held bat detectors. Students and naturalists are encouraged to monitor Salt Spring bats and to report the location of colonies to the Conservancy.

Guidelines for safe removal of indoor bat colonies can be found HERE:
