Cockroaches need three things to establish a colony: food, water, and warmth. Hillside's housing stock gives them exactly that. Dense brick bungalows and two-flats throughout the city, alongside single-family ranch and colonial homes across the suburbs, most with basements. Combined with Hillside's climate — a four-season climate with real winter cold, heavy snow, and notoriously strong winds off the lake — 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.
