Cockroaches need three things to establish a colony: food, water, and warmth. Washington Boro's housing stock gives them exactly that. Stone and brick farmhouses are common throughout this region, alongside newer subdivisions near the capital corridor. Combined with Washington Boro's climate — a climate shaped by the Susquehanna Valley, somewhat milder in winter than the mountains to the north — 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.
