Bats are excluded from your home or attic through a "Live Bat Exclusion" process. This involves bat-proofing your home with screens, caulking, caps, etc., and installing a one-way trap door at the entry point so bats can get out but not get back in.
How do I keep bats from hanging on my house?
Bats tend to roost in sheltered areas like under a porch or in a shutter. Using aluminum foil or shiny metal flashing in these areas can help deter them, though it won't completely keep them from hanging around your house.
Can you poison bats?
No, you cannot poison bats. There are no baits or chemicals that will get rid of bats, and in Michigan and most states, bats are protected animals due to their environmental benefits, such as controlling the mosquito population.
Why are bats in my basement?
Bats are most likely not living in your basement but end up there from the attic or a wall cavity within the house. They tend to enter roosting areas at high points and then navigate through open cavities to the basement.
Should I install a bat house?
Once bats are excluded from your home, it's a good idea to give them an alternative living area. Install a bat house on an open tree or pole at least 12-16 feet high facing the SE corner, and paint it black to absorb heat.
How do I know where the bats are getting in?
Bats leave a brown or black grease stain from the oils on their fur at an entry point they use repeatedly. They also leave urine staining and bat droppings (guano) outside of the hole.
How do I know what to repair to keep bats out?
Bats tend to use openings 1/2" or larger, so it's important to seal everything on the home, including ridge vents, gable vents, eaves, chimneys, drip edges, fascia boards, under soffits, etc.
