Cockroaches need three things to establish a colony: food, water, and warmth. Centenary's housing stock gives them exactly that. Elevated and pier-foundation construction is common given constant flood risk from surrounding marsh and tidal waterways. Combined with Centenary's climate — a coastal climate defined by high humidity, mild winters, and heavy rainfall much of the year — 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.
