Cockroaches need three things to establish a colony: food, water, and warmth. Hermleigh's housing stock gives them exactly that. A blend of older rural West Texas homes and desert-adapted construction near El Paso. Combined with Hermleigh's climate — a semi-arid to arid climate with hot summers, cold winters, low humidity, and significant day-to-night temperature swings — 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.
