What bat species are found in Massachusetts?
Massachusetts hosts several bat species, but the ones you are most likely to see are the big brown bat (Eptesicus fuscus) and the little brown bat (Myotis lucifugus). Big brown bats are larger, about 3.5 to 5 inches long, with brown fur and a slow, stable flight. Little brown bats are smaller, 2.5 to 4 inches, with glossy brown fur and quick, erratic movements. You might also spot the eastern red bat (Lasiurus borealis), which has rusty red fur, or the hoary bat (Lasiurus cinereus), a larger bat with frosted fur.

In Massachusetts, bats sightings usually improve when you slow down and match your first stop to the most useful ID markers and likely lookalikes. Use thestate wildlife huband theroute guideto narrow your first area, then check access, weather, and distance before you settle in. A short walk with one clear viewing plan often beats covering too much ground, especially when habitat changes fast from open edges to brush, wetlands, timber, shoreline, or neighborhood cover.
How can you tell bats apart from lookalikes?
At dusk, bats are often mistaken for swallows or nighthawks. Swallows glide more and often perch, while bats flap continuously and rarely land in the open. Nighthawks have longer wings with white patches and make a distinct call. Bats have visible ears and a tail membrane. A bat detector can help confirm by picking up echolocation calls. For reliable identification, focus on flight pattern and silhouette. Start with ourMassachusetts wildlife hubfor more local tips.
Where in Massachusetts are bats most often seen?
Your best odds are near water: ponds, lakes, and rivers. Popular spots include the Quabbin Reservoir, Cape Cod National Seashore, and Mount Tom State Reservation. Suburban areas with old trees and barns also attract bats. Backyards near water are great starting points. Visit parks like Borderland State Park for reliable evening activity.

When is the best time of year to see bats?
Bats are active from May through October, with peak activity in late summer when young bats are learning to fly. They hibernate in winter. The best time of day is from 15 minutes before sunset to about two hours after. Warm, calm evenings are ideal. Use a bat detector to increase your chances. Learn more aboutseasonal patterns.
How can you attract bats to your yard?
Install a bat house in a sunny spot facing south or southeast, ideally near a water source. Avoid using pesticides so bats have insects to eat. Plant native flowers that attract night-flying moths and beetles. Bat houses provide roosting sites, especially for females raising pups. Keep the house clean to prevent disease.

Are bats dangerous?
Bats are not aggressive and avoid humans. However, they can carry rabies, so never handle a bat with bare hands. If you find a bat inside your home, open a window or door and let it fly out. If a bat is injured or acting strangely, contact a wildlife rehabilitator. Bats are more beneficial than risky, eating thousands of insects each night.
What should you do if you find a bat in your house?
Stay calm and do not touch the bat. Open windows and doors to let it escape on its own. If it does not leave, wear thick gloves and use a container to trap it gently, then release it outside at dusk. If there is any chance of a bite or scratch, contact health authorities. For more advice, see ourbat safety page.
