Cockroaches need three things to establish a colony: food, water, and warmth. Tillman's housing stock gives them exactly that. Wood-frame homes dominate here, from historic textile-mill-era construction to newer suburban builds. Combined with Tillman's climate — a humid subtropical climate with hot, humid summers and mild winters, somewhat less humid and slightly cooler than the coast — 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.
