Cockroaches need three things to establish a colony: food, water, and warmth. Sequatchie's housing stock gives them exactly that. Older wood-frame homes dominate the more rural hill country, alongside newer subdivisions near Knoxville and other metro areas. Combined with Sequatchie's climate — a humid climate with real seasonal swings, cooler and wetter than the flatter parts of the state — 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.
