Local wildlife conditions in Ann Arbor.
An inspection in Ann Arbor usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Ann Arbor's seasonal timing lets you schedule treatment before the busy stretch rather than after it, which usually means faster service and a more accurate quote. A provider who works Ann Arbor and Michigan every day can point out the specific conditions that matter most here, and getting the scope, price, and follow-up terms in writing makes it easier to compare options. Ann Arbor sits in a humid continental climate, and that sets the pace for wildlife activity here: spring denning and fall (animals seek winter shelter). For Ann Arbor homes, the area is mostly urban, so wildlife pressure can differ from one block to the next depending on how tight the entry points are and how much food, water, or shelter is close by.
Brush, mulch and fallen fruit near the house give animals cover and food. Keep the edges tidy.What’s that noise?
- Heavy thumps at night: raccoons. - Rustling at dusk at the roof edge: bats. - A strong smell under the deck: skunks. - A big burrow beside the shed: groundhogs. - Quick scurrying at dawn and dusk: squirrels.
Baby season.
Never seal a hole while babies are still inside. Bat exclusion waits until pups can fly, usually by mid-August. Around Ann Arbor, most babies are born from about April through June. Mothers look for warm, dry spots like attics and chimneys.

Raccoons.
They tear open vents and roof edges. Never handle one. Heavy thumps at night usually mean a raccoon.
Tree squirrels.
Squirrels are busy at dawn and dusk. They chew small gaps into bigger holes, and wires too.
Opossums.
Opossums are quiet, slow and mostly harmless. They move into crawl spaces and under decks.
Skunks.
Skunks den under decks, sheds and porches. A strong smell after dark is the giveaway.
Groundhogs.
Groundhogs dig big burrows beside sheds, decks and foundations. Around Ann Arbor, they sleep through winter and wake hungry in early spring.
Bats.
Bats slip through gaps as small as a thumb. Look for droppings under a gap at the roofline.
Getting them out the right way.
- Check: look for babies first. - Door: a one-way door lets the animal leave. - Seal: heavy metal mesh on every gap. - Recheck: make sure nothing is trying to get back in. - Identify: figure out which animal it is.
Where animals get in.
- Gaps where the roof meets the wall. - Uncapped chimneys. - Crawl-space doors and foundation vents. - Under decks, porches and sheds. - Roof vents and soffit corners.
If an animal gets inside the house.
Keep kids and pets away. Is it a bat, and was someone asleep there? Call your health department first. Close interior doors so it stays in one room. Open an outside door or window in that room, then leave.
Droppings and cleanup.
- Wear gloves, a mask and old clothes. - Wet droppings down, then bag them. - Large attic messes are a job for pros. - Don’t sweep or vacuum droppings dry.
Keeping your yard less inviting.
- Pets: feed them indoors. - Birds: use a seed tray, and sweep up spills. - Fruit: pick up what falls. - Cover: clear brush and wood piles near the house. - Trash: locking lids, or keep bins in the garage.
Wildlife myths.
- Moving them is kind: often illegal, and babies get left. - Mothballs drive them out: they don’t, and they’re a health hazard. - Lights and radios work: only briefly. - Out in daylight means rabid: not always; mothers forage by day.
Birds in vents and chimneys.
Wait until the young have flown. Then fit a vent cover that still lets air out. Chimney swifts nest in chimneys in summer and leave in fall. Starlings and sparrows love dryer and bath vents. Most native birds are protected while nesting.
If an animal seems sick.
animal control or your local health department. Don't try to trap or touch it. Staggering, circling or acting unafraid can mean illness. Keep people and pets inside.
Pets and wildlife.
Bring pets in at night. your vet if your pet tangles with a wild animal. Keep pets' rabies shots up to date.
What a wildlife visit looks like.
They set a one-way door or trap. Later, they come back and seal up. Cleanup comes last. The tech walks the roofline and the foundation. They look for tracks, droppings and torn vents.
If a skunk sprays.
- Tomato juice: it doesn’t really work. - Eyes: keep the mix out; rinse with cool water. - Clothes: wash with baking soda added to the load. - Under the house: air it out; the smell fades over days. - People and pets: wash with peroxide, baking soda and dish soap.
Babies found alone.
Hurt or clearly orphaned? Call a wildlife rehabilitator. Baby animals alone are often just waiting for a parent. Leave them be and watch from a distance for a day.
Fencing that works.
- Climbers: an electric wire near the top stops raccoons. - Gardens: hardware cloth beats chicken wire. - Gates: keep gaps underneath to a couple of inches. - Diggers: bury wire mesh a foot down, bent outward.
