Cockroaches need three things to establish a colony: food, water, and warmth. Kellogg's housing stock gives them exactly that. Full basements are standard here, a near-universal response to the region's genuinely harsh winters. Combined with Kellogg's climate — a humid continental climate with warm, humid summers and some of the coldest, snowiest winters of any major U.S. metro — indoor cockroach pressure rarely lets up on its own.
Treatment starts with locating the harborage points — the tight, warm, food-adjacent spaces roaches actually live in — and applying gel bait directly there rather than spraying open floor space. This targets the colony at its source and avoids the resistance issues that plague over-the-counter sprays. We follow up to verify the population has collapsed, not just scattered.
