Cockroaches need three things to establish a colony: food, water, and warmth. Haviland's housing stock gives them exactly that. Wood-frame farmhouses and small-town homes dominate, nearly all built with basements for both winter cold and storm shelter. Combined with Haviland's climate — a climate shaped by its position in the Great Plains wheat belt, with hot summers and genuinely cold winters — 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.
