Cockroaches need three things to establish a colony: food, water, and warmth. Evanston's housing stock gives them exactly that. Housing spans century-old city bungalow neighborhoods to newer subdivisions throughout the collar counties. Combined with Evanston's climate — a humid climate with hot summers and winters cold enough for sustained snow cover most years — indoor cockroach pressure rarely lets up on its own.
Because sanitation and moisture are almost always part of the problem, our process pairs targeted gel-bait treatment with a review of what's drawing roaches in — a leak, exposed food storage, cluttered voids. Broadcast sprays just scatter a colony; bait placed at the harborage site eliminates it. A follow-up visit confirms results.
