This October, forget about the haunted house—build a bat house instead!

Bat Week is an annual, international celebration of the role of bats in nature

Did you know that 8 of our 9 native bat species are listed under the Massachusetts Endangered Species Act? Get ready for Bat Week by learning about these often-misunderstood creatures. Boost your “Bat IQ” by separating bat fact from fiction and learn how you can help bats.

Despite the threats, there are ways to help bats. Get ready to celebrate Bat Week at the end of the month by learning about what you can do to protect the bats in your backyard!

How you can help bats

One of the best ways you can support bat conservation is to put up an artificial roost, like a bat house. Bat houses give females a safe, warm place to raise their young. Since most female bats only have one pup each year, bat populations grow very slowly. Habitat loss and degradation is making it more difficult for bats to locate natural roost sites. Installing a bat house on your property can provide a safe environment for bats, while ridding your yard of pest insects, like mosquitoes, moths, and beetles. Bat houses can be purchased or you can build your own. MassWildlife offers instructions for building and installing a bar house.

Other ways to help:

• Educate yourself and others to help dispel myths and fears about bats. Read the Massachusetts Wildlife magazine article Bat Myths Debunked, to learn more about the fascinating and beneficial features of bats.
• Be a citizen scientist. If there is a colony of 10 or more bats on your property, please report it here. Colonies may be found in trees, buildings, attics, barns, sheds, or other outbuildings. This information will be used to help conserve the state’s endangered population of little brown bats.
• Protect habitat for bats. If you have old, dead, or dying trees on your property, leave them standing as potential roost sites for bats.
• If you must exclude or evict bats from your home, ensure the process is safe and humane by following MassWildlife’s recommendations found in the Massachusetts Homeowner’s Guide to Bats.
• Reduce pesticide use to ensure there are plenty of insects for bats to feed on.
• Create a bat-friendly landscape in your backyard by adding water features, such as a pond, and night-scented flowers.
