The Little brown bat measures between 2 to 4 inches in length (body only) with shiny, variable brown fur, and dark brown to black wings. Individual bats may weigh up to ½ oz. and have a wingspan exceeding 10 inches. These are the most common bats found in Nova Scotia.


The little brown bat is very widely distributed throughout most of North America including all but a few areas of the southern U.S and some parts of California. Their flight patterns are erratic and their roosting habits vary depending upon the time of day and year. They will live in trees, beneath rocks and in all types of buildings. In all situations they prefer sites that are warm, dark, and quiet. In homes, they’ll often inhabit the gable vents on the warmer south facing side. Within its’ northern range, the little brown bat is active from mid spring through early fall. In the early fall, these bats will migrate to seek out caves and begin a lengthy period of hibernation (up to seven months). The little brown bat is a surprisingly long-lived animal (up to 10 years+)


Although the little brown bat is a very beneficial insect predator, you should not want to share your home with them. They are host to several parasites, including tapeworm, fleas, bat bugs,(a close relative to the human bedbug) and rabies. There is also a potentially fatal airborne bacteria that grows on their droppings called Histoplasmosis. If you suspect that you are sharing your home with bats, please contact us for humane removal, and expert bat-proofing.


Mating season is in the fall, but fertilization doesn’t happen until spring. In the spring little brown bats form huge nursery colonies. A nursery colony may have thousands of bats in it. The female little brown bat gives birth to only one baby. During birth, the female hangs right-side up! The baby bat attaches itself to a teat. It nurses for about two weeks. It will fly when it is three weeks old.


Their diet is made up entirely of flying insects and they’ll consume up to half of their body weight during an average night.


The best way to prevent bats from entering a man-made structure is to shut the bats out. This is done by sealing with weather stripping, caulking, or screen any opening which they can enter. This includes cracks around window frames, chimneys, or other structures which vent warm air and attract bats. Bats potentially can enter holes as small as 3/4″ in diameter or 3/8″ by 7/8″.
