Cockroaches need three things to establish a colony: food, water, and warmth. Walsenburg's housing stock gives them exactly that. Housing spans historic mining-town construction to newer resort-driven development at elevation. Combined with Walsenburg's climate — a high mountain climate with dramatic seasonal extremes and a very short growing season — 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.
