local pest control pros who know campus bed bug pressure, carpenter ants
near the Huron River and 1920s foundation cracks.
Ann Arbor Runs Two Pest Markets in the Same City
Ann Arbor has two pest markets running in the same city. The first is the student one: high-density rental housing around campus, in Kerrytown and out toward Briarwood, where bed bugs and cockroaches move constantly through luggage and second-hand furniture. Proximity to the University of Michigan genuinely makes this a bed bug hotspot, and it’s a distribution problem rather than a cleanliness one. The second is the housing stock. Ann Arbor’s 1920s-to-1960s foundations have settled cracks that carpenter ants and pavement ants exploit, and the tree-heavy neighbourhoods — Burns Park, Angell, Kerrytown — make it worse. Carpenter ants are the single most treated pest here, especially near the Huron River and in older homes. Mice nest in Old West Side attics and Barton Hills garages every winter. PestAlly connects Ann Arbor homeowners and landlords with independent, local pros who know both sides.

Fall
Sep – NovOverwintering insects push into walls; rodents on the move
Rodent entry attempts peak with the first hard freeze
Mice indoors; bed bugs carry on in rental housing
One exception: Bed bugs in Ann Arbor follow the academic calendar, not the weather. Cases cluster around the move-in and move-out windows, when thousands of mattresses, sofas and boxes change hands across the city in the space of a couple of weeks. In high-density rental housing that’s a distribution network no amount of cleaning protects against, and treating a single unit in a building rarely settles it.
Services We Cover in Ann Arbor
A Burns Park century home, an Old West Side house or a campus rental — here’s what the local pros in our network handle.

Termites
Termite pressure in Ann Arbor builds out of sight — colonies feed inside joists and studs, so the first real sign is usually a swarm or a mud tube on the foundation.

Ants
Carpenter ants are the most treated Ann Arbor pest, nesting in damp wood near the Huron River, with pavement ants exploiting foundation cracks.

Roaches
Cockroaches are more common in high-density rental areas near campus, where shared buildings and constant turnover keep them moving.

Bed Bugs
Proximity to the U-M campus makes Ann Arbor a bed bug hotspot, spread through luggage and second-hand furniture in student housing.

Fleas
Pets and urban wildlife re-seed fleas through the warm months, though the Michigan winter knocks the outdoor population back.

Spiders
Cellar spiders, house spiders and wolf spiders use basements, garages, crawl spaces and woodpiles across Washtenaw County.

Yellow Jackets
Yellow jackets build ground and void nests through summer and turn aggressive in late summer as their food runs short.

Wasps
Paper wasps build under eaves, decks, porches and outbuildings right through the short but busy warm season.

Mosquitoes
The Huron River corridor, city parks, gutters and standing water support a real mosquito season through the warm months.

Flies
Cluster flies overwinter indoors in numbers, and drain flies trace to a specific source rather than needing the room treated.

General Insects
Boxelder bugs, lady beetles and stink bugs push into wall voids each autumn, plus silverfish in older Ann Arbor basements.

General Rodents
Mice and rats thrive in Ann Arbor’s older homes, nesting in Old West Side attics and Barton Hills garages through Michigan winters.

Most Common Pest Entry Points in Ann Arbor Homes
Settled cracks in 1920s-to-1960s foundations are what carpenter ants and pavement ants exploit, and Ann Arbor has a great deal of housing from exactly that period.
Damp or damaged wood — especially on properties near the Huron River — is where carpenter ants actually build the nest.
Heavy tree cover in Burns Park, Angell and Kerrytown keeps wood damp and puts limbs against rooflines, feeding both ant and rodent pressure.
Second-hand furniture, mattresses and luggage are how bed bugs enter a rental — the route is carried in rather than structural.
Attic and garage gaps in older homes are where mice get in, and Old West Side attics and Barton Hills garages are the classic Ann Arbor examples.
Why Ann Arbor Homes Deal With These Pests Specifically
Two Ann Arbor realities change how treatment has to work here — one about the trees, one about the university.
Carpenter ants are the most treated pest in Ann Arbor
Carpenter ants are the most treated pest in Ann Arbor, and they concentrate near the Huron River and in older homes. Along with pavement ants they exploit the settled cracks in 1920s-to-1960s foundations, and the heavy tree cover in Burns Park, Angell and Kerrytown keeps the surrounding wood damp enough to nest in.
Killing the ants you can see and leaving the damp wood and foundation cracks in place. Carpenter ants nest in wood that already has a moisture problem — until that’s corrected, the property keeps offering new sites.
Campus density makes Ann Arbor a bed bug hotspot
High-density student housing near campus, in Kerrytown and around Briarwood, spreads bed bugs through luggage and furniture. The turnover is constant, the buildings are shared, and second-hand furniture moves between addresses continuously — which is exactly the pattern bed bugs exploit.
Treating one apartment in a shared building. Bed bugs move through walls, risers and shared laundry, so unit-by-unit work in Ann Arbor rental housing usually relocates the problem rather than ending it.

What to Expect From a Local Pro’s Visit
Every Ann Arbor property is different, but the sequence stays the same — your local pro starts with the wood and the building type, because here those decide everything.
Inspect
Full inspection: foundation cracks, damp wood and gutters, tree contact, attic and garage gaps, and shared walls in rental housing.
→Identify
Confirming the species, since carpenter ant nest work, bed bug treatment and rodent exclusion are three completely different jobs.
→Treat
Matched to the finding: carpenter ant nest treatment and moisture correction, bed bug heat or chemical work, or rodent trapping and exclusion.
→Seal
Sealing foundation cracks, correcting the moisture that draws carpenter ants, trimming tree contact and closing attic and garage gaps.
→Follow Up
Ongoing service built around spring carpenter ant activity, the summer move-in wave and the first hard freeze.

Frequently Asked Questions
What are these big black ants in my kitchen?⌄
Almost certainly carpenter ants — the most commonly treated pest in Ann Arbor, especially near the Huron River and in older homes. They nest in damp or damaged wood and excavate galleries rather than eating it, so large black ants indoors with fine sawdust nearby usually point to a moisture problem in the structure.
Why are bed bugs such a problem in Ann Arbor?⌄
Because of the university. Proximity to the U-M campus and the density of student rental housing in Kerrytown and around Briarwood spread bed bugs constantly through luggage and second-hand furniture. It’s a distribution problem tied to turnover, not a reflection of how clean a building is.
How are mice getting into my house?⌄
Through the settled cracks and gaps that older Ann Arbor homes develop. Mice nest in Old West Side attics and Barton Hills garages through Michigan’s cold winters, and the routes they use are usually foundation cracks, garage thresholds and utility penetrations.
Do I need pest control through a Michigan winter?⌄
Yes, though the work changes. Outdoor insect activity stops, but mice are at their most active indoors and bed bug cases in rental housing carry on regardless of the season. Winter in Ann Arbor is when the indoor work matters most.
