Cockroaches need three things to establish a colony: food, water, and warmth. Gradyville's housing stock gives them exactly that. Housing here is often built into hillside terrain, ranging from historic rural homes to more modest recent construction. Combined with Gradyville's climate — a climate typical of Appalachian foothill country, with more precipitation and cooler temperatures at elevation — 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.
