Cockroaches need three things to establish a colony: food, water, and warmth. Wyandotte's housing stock gives them exactly that. Housing here dates heavily to the early-to-mid-1900s auto-industry era, with established neighborhoods and full basements standard. Combined with Wyandotte's climate — a climate shaped by the region's Great Lakes position, somewhat milder in winter than western Michigan's snowbelt — 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.
