How to Get Rid of Bats in the Attic

Know Your Neighbors

There are hundreds of types of bats in the world, but if you live in New England and you’ve got bats in your attic, they are almost certainly brown bats. Little brown bats (Myotis lucifugus) have a wingspan of approximately 8 inches and weigh less than half an ounce. Big brown bats (Eptesicus fuscus) can grow to be twice the size of little brown bats. Males typically roost individually, but female brown bats of both sizes form colonies in attics or barns when they are preparing to give birth (typically in June). Once the young have been born, little brown bats leave the buildings behind, preferring to hibernate in caves during the winter. Big brown bats, however, often hibernate right in homes — so if you’ve got winter houseguests, they’re probably of the big brown variety.

Why Are There Bats in My House?

Female bats are attracted to small sections of homes for nesting purposes. The most common areas to find bats include the walls, attic, and chimney.  Covered porches also provide the shelter bats are looking for in nesting sites.

A warm attic with low light is the perfect area for a bat to nurse her young. Unfortunately for the humans, bat feces and bat urine can accumulate and lead to foul smells and health issues.  Did you know that histomplasmosis is a dangerous disease associated with bat guano?

Bats enter homes through small gaps. A bat only needs a half-inch crack in a structure’s mortar to enter the area. The animals most often access homes through gaps between the soffit overhang and exterior siding.

On rare occasions, a bat could fly into your home through an open window. This is unlikely, and if it occurs, homeowners see the animal immediately. When bats sneak in through cracks, it can take years for people to notice.  Oftentimes, the first sign of a long-standing bat infestation is the overpowering smell of bat guano and bat urine.
