Ann Arbor's Diverse Pest Challenges
Ann Arbor is unlike any other city in Washtenaw County. The University of Michigan drives a massive rental housing market with high turnover — a perfect environment for bed bug spread. The city's commitment to tree preservation maintains a dense urban canopy that supports carpenter ants, squirrels, and spiders at elevated levels. And the Huron River's path through town creates a green corridor that connects pest habitats from Barton Pond through Gallup Park and beyond.
Housing ranges from pre-1900 Victorian homes in the Old West Side and Burns Park to mid-century ranches in the neighborhoods off Packard and Stadium, to newer construction in developments along the city's fringes. Each neighborhood has characteristic pest pressures driven by housing age, tree cover, and proximity to natural areas.
What Ann Arbor Homeowners Encounter
- Carpenter ants — Ann Arbor's mature oak and maple canopy supports one of the highest carpenter ant populations in southeast Michigan. Any home with a moisture issue near a mature tree is a candidate for carpenter ant colonization.
- Bed bugs — The constant turnover of student housing near campus, combined with international travel and used furniture circulation, keeps bed bug introductions happening year-round. The Central Campus and Kerrytown areas see the highest incidence.
- Mice — Even central Ann Arbor neighborhoods have mouse pressure because the parks, the Arb, and the Huron River corridor run through the middle of town. No residential street is far from natural mouse habitat.
- Stink bugs and boxelder bugs — Fall-invading insects are persistent across Ann Arbor's older neighborhoods where homes have more entry points than modern construction. South-facing walls on homes near boxelder and silver maple trees see the heaviest activity.
