What You Need to Know About Bats in Your Home
Bats are the only flying mammals and are incredible for the environment. A single bat can eat up to 6,000 insects a night, drastically reducing mosquito populations and the spread of West Nile virus. However, when they move into your living space, they become a serious problem.
In Michigan and the Northeast, Big and Little Brown Bats are the most common species found in residential attics.
How They Get In- With highly flexible, cartilage-based bodies, bats can squeeze through gaps as small as a 3/8 inch. They land on an exterior surface and crawl inside.
Signs of an Infestation- Listen for distinct chirping, scratching, or fluttering in your walls or attic. They navigate via echolocation, but their physical movements are noisy.
The Danger of Guano- A bat infestation comes with an unforgettable odor. Accumulated bat guano (droppings) harbors bacteria and fungi that are hazardous to the human respiratory system.
Rabies Risk- While only a very small percentage of bats carry rabies, it is still a risk. Never handle a bat yourself; contact your local health department if exposed.

Common Signs You Have Bats Nesting in Your Attic
If you suspect you have a bat problem, early detection is key to preventing property damage. Bats are excellent at hiding, but they leave behind a few telltale clues.
Look and listen for these common warning signs:
Nighttime Noises- You hear scratching, scurrying, or rustling in the ceiling and walls, particularly just after sunset or before dawn.
Attic Chatter- You hear high-pitched chirping or squeaking sounds coming from above.
Indoor Sightings- You’ve found a bat inside your living space, which is often a strong indicator of a larger colony roosting in the attic.
Dusk Activity- You consistently see bats swooping and flying around your roofline as the sun goes down.
Active Entry Points- You spot bats physically flying in or out of a specific hole, gap, or damaged area on your roof.
Greasy Smudge Marks- You notice dark, oily dirt marks (caused by the oils on their fur) around the louvers of your gable vents or along the siding.
Guano Buildup- You find small, dark droppings accumulating on your front porch, deck, or windowsills right below their entry points.
