Cockroaches need three things to establish a colony: food, water, and warmth. Sultana's housing stock gives them exactly that. A blend of established coastal towns and newer construction, both shaped by the region's mild, moisture-moderate climate. Combined with Sultana's climate — a mild climate with persistent coastal fog in many areas, especially closer to the shoreline — 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.
