Cockroaches need three things to establish a colony: food, water, and warmth. Chattaroy's housing stock gives them exactly that. Wood-frame homes with basements dominate this dry landscape, built for cold winters rather than the persistent rain seen west of the Cascades. Combined with Chattaroy's climate — a continental climate with genuine seasonal extremes, far drier than western Washington year-round — indoor cockroach pressure rarely lets up on its own.
We start with an inspection to identify the species and the source — sanitation issue, moisture problem, or entry point. Treatment centers on gel bait placed in cracks, voids, and under appliances, not broadcast spraying, since German cockroaches in particular have developed resistance to many surface sprays. A follow-up visit confirms the bait is working and the population is dropping.
