Expert Michigan Bat Removal & Prevention

We do not use poisons, chemicals, or traps, as exterminating bats is illegal in Michigan. Instead, we use a highly effective and humane process called live bat exclusion. First, we conduct a thorough inspection to identify every primary and secondary entry point the bats are using to access your home. We then install one-way exclusion devices (often called bat valves or doors) over the active entry points and seal up all other potential gaps. When the bats leave at dusk to hunt for insects, the one-way door allows them to exit safely but prevents them from re-entering. Once we are certain all bats have vacated, we remove the devices and permanently seal the final holes.

Yes. In Michigan, there is a strict bat maternity season that typically runs from early June through mid-August. During this time, female bats give birth to pups that are entirely dependent on their mothers and cannot fly. If we were to perform an exclusion during this window, the mothers would be locked out, and the flightless pups would be trapped inside your home to die—leading to severe odor, pest issues, and unethical treatment of protected wildlife. During the maternity season, we can inspect your home and prep it by sealing secondary holes, but the actual exclusion devices cannot be installed until the pups are old enough to fly.

No, it is strictly illegal. Bats are a protected species under Michigan law, and several species native to our state (such as the Indiana bat and the Northern long-eared bat) are federally protected under the Endangered Species Act. Because they consume millions of mosquitoes and agricultural pests every night, bats are a vital part of our local ecosystem. As a licensed professional service, we strictly adhere to all state and federal laws to ensure the bats are removed safely, humanely, and legally.

While both can cause scratching noises, there are a few distinct differences. Bat activity is highly cyclical; you will typically hear shuffling, squeaking, or light scratching at dusk as they wake up to leave, and again at dawn when they return. Unlike mice, bats do not chew wood or wires, so you won't hear gnawing sounds. The most obvious sign of a bat infestation is the presence of bat guano (droppings) near entry points outside your home or accumulated in your attic. Guano looks similar to mouse droppings but is highly brittle, often sparkly (due to crushed insect shells), and can produce a strong, pungent ammonia smell.

Yes, bat guano can pose a significant health risk. When guano accumulates and dries out, disturbing it can release microscopic fungal spores into the air. Inhaling these spores can cause Histoplasmosis, a serious respiratory infection. Because of this risk, you should never attempt to sweep or vacuum bat guano yourself. After the bats have been successfully excluded from your home, we offer complete attic restoration and guano cleanup services. We use professional-grade respirators and HEPA vacuums to safely remove the waste, followed by thorough sanitization and deodorization of the affected area to keep your family safe.
