Cockroaches need three things to establish a colony: food, water, and warmth. Marydel's housing stock gives them exactly that. A mix of beach cottages, newer coastal construction, and farmhouses on the flat Delmarva farmland, many built on crawl spaces given the high water table. Combined with Marydel's climate — a coastal climate milder in winter than northern Delaware, with hot, humid beach-town 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.
