When you discover bats in your attic, chimney, or walls, your first concern is often your family’s safety. The next question is: How much will bat removal cost? At Michigan’s Bat Expert, we get this question every day, and we’re here to break it down.
In Michigan, bat removal costs typically range from $200 to $5,000, depending on several key factors like the size of the infestation, the complexity of the structure, and whether exclusion and cleanup are required.
What Factors Affect Bat Removal Costs in Michigan?
The cost of bat removal in Michigan can vary widely, from as low as $200 for a small exclusion to over $5,000 for a full attic restoration. So what drives those costs?
Here’s a detailed look at the key factors that affect your bat removal estimate:
1. Bat Colony Size
The size of the bat infestation plays a major role in pricing. Larger colonies:
- Leave behind more guano, increasing cleanup labor and materials
- Create stronger odors that require deodorization
- May have more pups, requiring careful timing around Michigan’s maternity season
For example, removing a small colony of 5 bats from a single vent might cost $350–$500, while a colony of 100 bats roosting throughout your attic could exceed $3,000 after guano cleanup, attic restoration, and exclusion work.

2. Number of Entry Points & Structural Complexity
Bats can enter through any gap larger than 3/8 inch, and every one of those must be located and sealed.
Costs increase when:
- Your home has complex rooflines, dormers, or multiple gables
- Vents, soffits, fascia, and chimney caps all require sealing or replacement
- Ladder work or crawlspace access is required
Homes with intricate architecture or older construction typically require more labor and materials, increasing the total exclusion cost.
3. Guano Cleanup & Sanitization
Bat droppings (guano) can contain Histoplasma capsulatum, a fungus that causes Histoplasmosis, a dangerous lung disease. A professional cleanup includes:
- HEPA vacuuming of droppings
- Disinfection with EPA-approved antimicrobial agents
- Removal and replacement of contaminated insulation
Professional spot cleaning and decontamination alone can range from $500 to $2,000+, depending on the severity and square footage affected.
4. Location in Michigan
Pricing also depends on where you live in the state. For example:
- Urban areas like Ann Arbor, Chelsea, or Lapeer often have higher service rates due to travel, labor costs, and permit requirements
- Rural areas may have lower overhead, but additional trip charges might apply for remote properties
Local regulations, building codes, and accessibility can all influence your final quote.
Why DIY Bat Removal Could Cost You More
Attempting bat removal without a licensed professional may be illegal. Trying to remove bats from your home yourself may sound like a way to save money, but in reality, it can be dangerous and ineffective. Michigan law protects certain bat species and requires humane exclusion methods.
Here’s why homeowners should think twice before attempting bat removal without professional help:
1. It May Be Illegal in Michigan
Michigan law protects several bat species, including the endangered Northern Long-Eared Bat.
During maternity season (typically May to August), it is illegal to kill bats or remove them while pups (baby bats) are unable to fly. If you seal off an entry point during this time:
- You may trap flightless baby bats inside your home, causing them to die
- Mothers may return repeatedly, damaging the structure further
- You could face violations under the Michigan Natural Resources and Environmental Protection Act (NREPA)
✅ Licensed professionals understand when and how legal exclusion can occur and use DNR-compliant methods.
2. Guano Cleanup Risks Serious Health Issues
Bat droppings (guano) can harbor Histoplasma capsulatum, a fungus that causes Histoplasmosis, a potentially serious lung infection. When disturbed by sweeping, vacuuming, or insulation removal, spores become airborne and enter your lungs.

DIYers often lack proper protective gear (PPE), HEPA-rated filtration systems, and safe disposal practices for biohazard waste.
Inhaling guano dust while cleaning an attic can lead to long-term respiratory issues and even hospitalization.
3. Bats May Return If Not Fully Excluded
Even if you manage to remove a bat or two, failing to locate every access point means the colony will likely return. Bats only need a gap as small as 3/8 of an inch to re-enter. Most homeowners miss gaps in roof vents and soffits, cracks in chimney flashing, seams behind fascia boards, and warped siding near the roofline.
Professional exclusion includes a full home inspection, identification of entry points, one-way exit devices, and sealing with wildlife-grade materials that hold up over time.
We’ve seen DIY attempts lead to electrical fires, ceiling collapses, and insurance claim denials because the infestation wasn’t handled properly.

We begin with a thorough inspection of your attic, roofline, vents, soffits, and siding to identify all signs of bat activity. Our team pinpoints every entry and exit point bats are using, down to gaps as small as 3/8 of an inch.
2. Humane Bat Exclusion
Next, we install one-way exclusion devices that allow bats to leave but prevent them from getting back in. This approach is fully legal and safe for protected bat species in Michigan. After all bats have exited, we return to remove the devices and seal those final openings.

Michael knows his job and was both professional and efficient. I am receiving a good experience taking care of the ‘bats in my belfry’!
Now, a year after my initial bat extermination I have unfortunately seen signs they have returned. Due to Michigan Bat Experts awesome warranty, Nate and Cameron returned today and started a fresh extermination process. They were exemplary employees and completed their work within an acceptable timeframe. Thank you for taking good care of this ongoing problem!UPDATE as of April 2025
After discovering the bats are still getting into my attic, I had Jesse return today for another inspection. I could tell Jesse takes his job seriously and performed an over abundance of caution with sealing up all the openings he found all around my roof and eves. Not to say this wasn’t done in the past 2 years of having you take care of my bat problem, just that weather had eroded the previous caulk. I commend Jesse on his expertise and professional manner and hope we’ve taken care of the problem finally. Thank you.
I also wish to thank Brittany in your office for having Jesse scheduled to come out so rapidly. Good job✅
