Cockroaches need three things to establish a colony: food, water, and warmth. Cayuga's housing stock gives them exactly that. A mix of historic river-town homes, university-area housing near Bloomington, and hillside construction typical of southern Indiana's limestone terrain. Combined with Cayuga's climate — a climate that behaves somewhat like the upper South, with shorter, milder winters than the rest 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.
