Wyoming is home to 18 species of bats that sometimes cross paths with humans. Depending on where and how the bat is found determines what you should do: 
 

• First, do not touch or handle bats. Bats can transmit rabies prior to having symptoms, and, like any wild animal, can act aggressively if they feel threatened. Anyone bitten by a bat should seek medical attention and try to safely contain the bat for testing. 

• If a bat is inside unused parts of buildings, like the rafters of a shed, barn or attic, installing one-way doors for about a week will let the bats fly out but not back in. They are best-used in the late summer or early fall. Over the summer, females may become separated from their young — called pups — by a one-way door. Since the pups can’t fly and need to nurse several times each night, they will not survive alone.

• If a bat gets into a house, open a window — minus the screen — and shut off the room overnight. The bat should fly out on its own.

• Bats sometimes are reported on the outside of buildings and during the day. It’s not unusual to see a bat roosting, or even flying, in daylight. An active daytime bat is likely searching for a place to sleep. If a bat is spotted sleeping, leave it alone. Bats flying during the winter could be a sign of white-nose syndrome, a disease in bats. Report sightings to Game and Fish. 

• If you find an injured bat, call Game and Fish. People should not attempt to rehabilitate a bat nor keep it as a pet. That is illegal without a permit from Game and Fish.
