Bats and Rabies

Bats can transmit rabies to humans. Do you have bats in your attic?

Bats in AtticAttics are the place in a house where bats usually choose to roost and raise their young.  After a few hot summer days, an attic can become too warm for the bats, forcing them into people's living quarters as they search for cooler places to roost.

If you find a bat inside your house, do not release the bat outdoors until you can safely determine that no exposure occurred.

An exposure occurs when:
  • A person has had direct contact with a live bat and cannot rule out that a bite or scratch may have occurred or
  • A sleeping person awakens to find a bat in the room or
  • An adult witnesses a bat in the room with a previously unattended child, a mentally disabled person, an intoxicated person, or a pet.


Decisions about rabies exposure and the possible need for treatment should be made by your doctor.  If you think you or someone in your home may have been exposed to a bat, contact your doctor.

Or, if you have questions about potential rabies exposure please call the Mass. Dept of Public Health  Division of Epidemiology and Immunization at 617-983-6800.  An epidemiologist is available 24/7 for questions.  For additional information about rabies, you may also visit the MDPH website at
