Cockroaches need three things to establish a colony: food, water, and warmth. Falfurrias's housing stock gives them exactly that. Slab construction dominates here, from established Hill Country neighborhoods to newer subdivisions and South Texas ranch-country homes. Combined with Falfurrias's climate — a climate shaped by limestone Hill Country terrain around Austin and San Antonio, and near-subtropical conditions farther south — 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.
