Des Plaines sits in the O'Hare airport corridor in northwest Cook County, with the Des Plaines River running through it. Two features shape its pest pattern. The first is the housing: a large share of older frame homes, settled and aging, with the gaps and harborage that age brings, which gives rodents and the occasional cockroach a steady foothold. The second is water. The Des Plaines River floods periodically, and when it does, it raises moisture pest pressure across the low-lying parts of the city: damp basements and crawl spaces draw camel crickets, drain flies, and the conditions cockroaches and rodents favor. The river floodplain also sustains mosquito breeding through the summer. The O'Hare corridor brings a base of commercial and hospitality accounts. Between the older frame housing and the flood-prone river, Des Plaines deals with steady moisture-driven and rodent pest pressure.

When to call a Des Plaines exterminator
In Des Plaines, the river and the older housing drive the calls. After the Des Plaines River floods, watch basements and crawl spaces for camel crickets, drain flies, and the dampness that draws cockroaches and rodents; drying the space out does more than spraying. Rodents push into the older frame homes in fall, so seal entry points before October, and seeing one mouse means more are coming. Cockroaches in the older housing reward early action, and in multi-unit buildings they spread between units. For mosquitoes off the river floodplain, a barrier program started in May keeps the yard usable through the July and August peak. A business in the O'Hare commercial corridor benefits from a scheduled commercial program rather than reacting to each problem.
