Cockroaches need three things to establish a colony: food, water, and warmth. Duncanville's housing stock gives them exactly that. Slab-on-grade construction dominates here, built over the region's notoriously expansive Blackland Prairie clay. Combined with Duncanville's climate — a hot, humid climate for much of the year, with brief but genuine winter cold snaps — 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.
