Common nuisance wildlife in Michigan
Raccoons tear open soffits, roof vents and chimney tops to den in attics, especially in late winter and spring when females look for a safe spot for their young. Fox squirrels, gray squirrels and red squirrels chew into attics through soffit gaps and roof returns. Flying squirrels are active only at night and often get into attics in groups, so the noise starts after dark.
Skunks dig under decks, porches, stoops and sheds, and you usually smell them before you see them. Groundhogs, also called woodchucks, burrow under sheds, slabs and foundations, which can undermine concrete over time, and they love vegetable gardens. Opossums take shelter under decks, in garages and in crawl spaces and wander from yard to yard.
Squirrels in the attic often mean chewed wiring, which is a fire risk. Raccoons can tear up insulation and ductwork and leave large latrines. If you are not sure what animal you are hearing, the time of day helps: squirrels are busy at dawn and dusk, raccoons and flying squirrels at night.
Michigan rules on wildlife removal
Wildlife in Michigan is managed by the Department of Natural Resources. Rules on trapping, relocating and euthanizing animals vary by species, and some animals have specific protections. Licensed nuisance wildlife control businesses operate under DNR permits and know which methods are allowed for each animal. Ask any company you hire how they handle the animals they catch.
Moving a trapped animal to a park or woods may sound kind, but it can spread disease, often leads to the animal's death in unfamiliar territory, and may not be legal for that species. Before you trap anything yourself, check the DNR's current guidance on nuisance animals, or let a licensed company handle it.
Rabies, roundworm and other health concerns
Skunks are one of the species that can carry rabies in Michigan, along with bats. Stay away from any animal acting strangely, such as stumbling, showing no fear of people, or acting aggressive. Raccoon droppings can contain raccoon roundworm eggs, so attic latrines should be cleaned with gloves, a respirator and care, or by a pro.
If you or a pet are bitten or scratched by a wild animal, wash the wound with soap and water and contact a doctor and your local health department right away. Keep pets' rabies vaccinations current. If a bat is involved, see our bat guide for what to do. Do not try to catch the animal yourself.
How wildlife removal and exclusion work
A licensed company will inspect the house, find every entry point, and remove the animals using live traps or one-way doors that let animals leave but not return. In spring, they check for young before sealing anything, since trapping a mother outside leaves babies stranded and creates a bigger problem.
After the animals are out, openings are sealed with heavy-gauge screen, metal flashing and chimney caps. Some jobs also need insulation removal and attic cleanup. Repairs usually account for a large share of the cost, but they are what stops the next animal from moving in. Ask for photos of the entry points before and after the work.
What you can do yourself
- 1Install a chimney cap and screen roof and soffit vents.
- 2Keep trash in bins with tight lids, stored in the garage if possible.
- 3Feed pets indoors and clean up spilled birdseed.
- 4Trim tree branches back several feet from the roof.
- 5Install an L-shaped hardware cloth barrier buried around decks and sheds.
- 6Repair loose soffits and fascia boards before late winter.
When to call a licensed pro
- An animal is in the attic, chimney or walls.
- You suspect young animals are inside.
- An animal is acting strangely or aggressively.
- Entry points on the roof need to be sealed.

Wildlife: common questions
Can I trap and relocate a raccoon in Michigan?
Michigan DNR has rules about trapping and relocating wildlife, and they vary by species and situation. Check the DNR's current nuisance animal guidance before setting a trap, or use a licensed nuisance wildlife company that already works under DNR permits.
How do I know if there are baby animals in my attic?
Spring is baby season for raccoons and squirrels. Listen for high-pitched chirping or crying, and watch whether an adult keeps returning to the same spot. A pro will check for young before sealing any entry.
What does wildlife removal cost?
Typical ranges are $300 to $1,500 depending on the animal, the number of entry points and repairs. Attic cleanup is extra. See our pest control cost guide for more. A licensed local company can inspect and give you a firm price; you can request a quote.
Do mothballs or ammonia drive animals out?
Not reliably. Animals often ignore them, and mothballs are not labeled for use in attics against wildlife, so using them that way breaks the label and can make your home smell for months. Exclusion is the dependable approach.
