Cockroaches need three things to establish a colony: food, water, and warmth. Nemours's housing stock gives them exactly that. A blend of historic coal-camp construction and modest newer homes, both shaped by the region's steep, forested terrain. Combined with Nemours's climate — a humid continental climate moderated by elevation, with cold, snowy winters and mild summers typical of the Appalachian Mountains — 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.
