Cockroaches need three things to establish a colony: food, water, and warmth. Louise's housing stock gives them exactly that. Slab construction is standard here, built for heat and flood risk rather than winter cold. Combined with Louise's climate — a humid subtropical climate with intense summer heat and humidity, heavy rainfall, and a real hurricane season — 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.
