Cockroaches need three things to establish a colony: food, water, and warmth. Blair's housing stock gives them exactly that. Newer suburban subdivisions dominate here, built during the Omaha metro's recent growth, with basements standard for winter protection. Combined with Blair's climate — a four-season Great Plains climate with real winter cold, moderated slightly by the urban heat of the metro area — 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.
