The most common problem with bats is entering homes and buildings, where they can inadvertently have contact with people. Removing bats from buildings is regulated, and it’s a better idea to prevent them from entering homes and other buildings than trying to remove them, Wildlife Illinois advises.
Bats are protected by the Illinois Wildlife Code and cannot be shot, trapped, transported or held in confinement except in cases when a bat is found in an area where it may have contact with humans or domestic pets, according to the state health department.
You can remove bats from the living area of your home— defined as any room in your house that you actively use — at any time of year, the state health department reports. If bats or bat colonies are found in parts of your home that are not a living area, such as an attic, they can only be removed from March 15 to May 15 and from August 5 to October 30 when outdoor temperatures are higher than 50 degrees Fahrenheit at dusk. The restrictions on timing are intended to protect young bats who are unable to fly.
If you think you may have bats in your attic or elsewhere, watch the building exterior from a half hour before sunset until dark to determine where they are gaining access, Wildlife Illinois advises. Typical entry points are small openings in roofs, eaves, dormers and gables; holes or gaps in siding; chimneys; and attic and roof vents.
Any gaps larger than a half-inch by 1½ inches or holes greater than 5/8 of an inch in diameter need to be sealed to prevent access. Small access points should be sealed first, then once bats have left the roost in the evening, larger entry point should be temporarily sealed with one-way doors.
One-way doors can be made of plastic mesh or ¼-inch wire screening. Cover the entry point with a 2-foot to 3-foot piece of the mesh or screen, leaving 3 inches to 5 inches between the screening and the building so the bats can crawl out. Fasten the top of the mesh or screening to the building with duct tape or staples, but leave the bottom unsecured. Once all bats have left the building, which may take several days, remove the one-way door and permanently seal the openings.
One-way doors should be used before babies are born in May and June so they don’t starve if the mother has been excluded, Wildlife Illinois advises. If there are young bats in a building, wait until late July or August to exclude bats and seal openings.
If a bat enters the living area of your home, do not panic. Do not try to catch or handle the bat, and do not knock It out of the air, Wildlife Illinois advises. Try to confine the bat to an area of the house with outdoor access by closing the door to the room. Open any exterior windows and doors in the room to allow it a way to escape.
Keep people and pets out of the room until the bat escapes, which may take several hours if the bat is disoriented. Also, keep in mind a bat in an enclosed area may make sharp turns and swoop down in flight. It is not attacking you; it is trying to orient itself so it can get back outside.
Bats found on the ground outside may be sick or injured or a young pup that is learning to fly. Bats on the ground may be aggressive because they are vulnerable, Wildlife Illinois reports. If you find a bat on the ground, remove young children and pets from the area to keep them safe.
You can relocate a bat found on the ground by scooping it into a coffee can or similar container, using a piece of stiff cardboard to carefully slide under the bat to lift it from the ground. Release the bat at the base of a tree, placing the container on the ground gently and pulling the cardboard away slowly. Walk away from the bat quickly. A healthy bat will crawl up the tree after it has oriented itself. Wear leather gloves while handling the bat; do not handle bats with your bare hands.
If the bat has bit a person or a pet, do not release it, Wildlife Illinois advises. It should be kept for rabies testing by your local animal control or health department.
In Illinois, bats cannot be removed without a permit from the Illinois Department of Natural Resources. If you need bats removed from your property, hire a wildlife control operator who has experience with bat exclusion and humane removal.
All wildlife in Illinois are under the jurisdiction of the Illinois Department of Natural Resources. The Forest Preserve District of Will County does not treat, rescue or remove wildlife from public or private property. Both the Illinois Department of Natural Resources and Wildlife Illinois maintain lists of wildlife rehabilitators you can contact for assistance with injured wildlife.
