The little brown bat is the most common bat in Alberta. The little brown bat weighs approximately 8.5 g and it is light brown to reddish or dark brown in color. Although some people are afraid of bats, and think they are spooky and scary, little brown bats are very beneficial to humans. They help people to enjoy the outdoors more by devouring large quantities of pest insects. This may even further help humans by limiting the spread of diseases and reducing the need for pesticides. Little brown bats have their place in nature, just as any other creature does!
