Cockroaches need three things to establish a colony: food, water, and warmth. Crete's housing stock gives them exactly that. Historic brick two- and three-flat buildings make up much of the older city housing stock, alongside postwar suburban tract homes. Combined with Crete's climate — a climate shaped by proximity to Lake Michigan, with colder, snowier conditions than much of downstate Illinois — 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.
