Do not panic; this is exciting. Bats are not the horrible monsters popular culture make them out to be. In fact, bats are nature’s pesticide and save the agricultural industry billions across North America. They also protect you from mosquitos and other pesky insects.
It is quite normal for some Canadian bat species to roost in buildings. The most common are the Big Brown Bat (Eptesicus fuscus), the Little Brown Myotis (Myotis lucifugus), and occasionally the Northern Myotis (Myotis septentrionalis). In British Columbia, there are two additional species of bat that could roost in homes: the Yuma Myotis (Myotis yumanensis) and the Townsend’s Big-Eared Bat (Piecotus townsendii). Don’t be fooled, the 19 species of bats found in Canada all eat insects, NOT blood! So no need to be scared of bats.
