Cockroaches need three things to establish a colony: food, water, and warmth. Killen's housing stock gives them exactly that. Mostly single-family ranch and newer suburban-style homes on residential lots, reflecting Killen's role as a small bedroom town near the Shoals. Combined with Killen's climate — Humid subtropical climate of the Tennessee Valley/Shoals area, with hot summers, mild winters, and heavy spring rainfall. — 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.
