Michigan Bat Control- Safe, Legal, and Humane Removal

No, it is illegal to kill bats in Michigan. Bats are classified as a protected species, and several species found in the state are federally protected under the Endangered Species Act. It is strictly prohibited to kill, trap, or harm them. The only legal and responsible way to remove bats from a residential or commercial property is through a process called humane live exclusion.

Absolutely not. There are no legally registered bat poisons or pesticides available on the market. Attempting to poison bats is not only a violation of state and federal laws, but it is also highly counterproductive. Poisoned bats will likely die inside the walls or attic of the structure, leading to severe odor issues, secondary pest infestations (like maggots and flies), and potential health hazards. Poison-free exclusion and remediation is the only safe and lawful approach.

The most effective method is a structural exclusion. This involves a thorough inspection to identify every primary and secondary entry point on the building. Professional, one-way exclusion valves are installed over the active entry points. These devices allow the bats to safely fly out at night to feed, but prevent them from re-entering the structure. Once the colony has been completely safely evacuated, the one-way doors are removed, and the gaps are permanently sealed.

Yes. Because bats are protected, exclusions cannot be performed during the bat maternity season, which in Michigan typically runs from early June through early August. During this window, mother bats are raising flightless pups inside the roost. Installing exclusion devices during maternity season would trap the babies inside to die, resulting in a violation of wildlife laws and creating severe sanitation issues inside the building. Safe exclusions are generally performed in the late summer, fall, or spring.

Bats have excellent memories and strong homing instincts; they will attempt to return to their established roosting site. Permanent removal requires meticulous, professional-grade sealing of the entire structure using specialized materials like heavy-duty sealants, hardware cloth, and custom metal flashing. Utilizing a professional service that backs their exclusion work with an industry-leading 5-year wildlife removal warranty ensures that your property remains completely secure and protected against future re-entry.
