Cockroaches need three things to establish a colony: food, water, and warmth. Cortland's housing stock gives them exactly that. A blend of dense urban multi-family buildings and single-family suburban homes, nearly all with basements given the region's cold winters. Combined with Cortland's climate — a humid continental climate with hot, humid summers, cold and often harsh winters, and significant lake-effect influence near Lake Michigan — 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.
