Cockroaches need three things to establish a colony: food, water, and warmth. Chebeague Island's housing stock gives them exactly that. A blend of historic coastal architecture and newer development, with basements standard given the cold winters. Combined with Chebeague Island's climate — a coastal climate moderated by the Gulf of Maine, with cold winters and cool, pleasant summers — 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.
