Connect With a Local Pro Who Knows Washtenaw County

Ypsilanti is older and harder-worn than its neighbour. The Huron River runs through the middle, Depot Town and the Normal Park streets are full of 1880s to 1920s frame houses, Eastern Michigan University turns over students every August, and the Willow Run industrial ground sits to the east. Old wood-frame housing carrying heavy rental use is the core of the pest picture here. PestAlly is a free service connecting Ypsilanti homeowners with independent, licensed local pest control pros working Washtenaw County.

Why Ypsilanti

Why Ypsilanti Homes Get Hit Harder Than Most

A large share of the housing is century-old frame stock that has been converted to rentals, and that combination is the local problem. Houses built between 1880 and 1920 as single families now run as multiple units, with shared walls, subdivided floors, added kitchens and old service penetrations connecting spaces that were never meant to be separate. German roaches and bed bugs move through that freely, and August student turnover reintroduces both every year, which is why single-unit treatment so reliably fails here.

The river and the old fabric supply the rest. The Huron corridor holds damp, shaded ground and standing backwater that breeds the Culex mosquitoes carrying West Nile in Michigan, and it gives raccoons, squirrels and rats a route through the city. The frame houses sit on stone and block basements with original rim joists, sagging porches and wood trim close to soil, so mice come in below and carpenter ants nest in whatever has stayed damp — and there is a great deal of deferred maintenance in this stock.

Services

The Pest Problems Ypsilanti Calls About Most

Bed Bug Treatment

Converted houses running as multiple units spread them through added walls and old penetrations, and August turnover reintroduces them.

Cockroach Control

German roaches travel between subdivided units freely, so a single treated flat in an Ypsilanti conversion is reseeded within weeks.

Rodent Control

Mice enter century-old stone basements at the rim joist, while Norway rats work the river bank and the industrial ground.

Ant Control

Carpenter ants nest in sagging porch framing and damp sills — on this housing stock the moisture is usually the real finding.

Mosquito Control

The Huron corridor holds shaded backwater all summer, breeding the Culex that carry West Nile in Michigan.

Spider Control

Old stone basements stay cool and damp year-round, so camel crickets, centipedes and cellar spiders never die back.

Common Questions

Ypsilanti Pest Questions, Answered

We treated our unit and the roaches came straight back.
In a converted Ypsilanti house that is expected. These buildings were single families, so the walls between units are later additions with gaps around plumbing, wiring and old chimney runs, and German roaches move through them freely. Treatment has to cover the whole building. Report it to the landlord in writing — Michigan landlords have habitability obligations and a written record is what triggers proper action.
Bed bugs every August without fail.
That is student turnover, and it is the single most reliable way bed bugs spread. Mattresses, sofas and boxes move between houses, flats and storage over a few weeks, and kerbside furniture in August is very often there for a reason. Inspection at every changeover — seams, box springs, headboards, behind the headboard wall — is the only thing that gets ahead of it.
Our porch is sagging and now there are big ants.
Those go together. Carpenter ants nest in damp or decayed wood rather than sound timber, and a century-old porch with failed flashing or a leaking roof above it is exactly the condition they want. Treating the ants without repairing the water source simply moves them a few feet along the same framing and buys a season.
Rats along the river.
Norway rats burrow in the Huron bank and use the corridor to travel through the city, and rising water floods those burrows and pushes them toward buildings. They come in at grade and through cracked clay sewer laterals rather than from the roof, so exclusion at ground level and burrow work is what actually reduces them.
Is termite treatment needed on a house this old?
Probably not in Washtenaw County. Termite pressure in Michigan is low, and on a century-old frame house the damaged wood is nearly always carpenter ants or straightforward rot from a leaking porch, gutter or window. Get an identification before agreeing to anything — on this housing stock, moisture repair is usually the real answer.
