Cockroaches need three things to establish a colony: food, water, and warmth. Richwood's housing stock gives them exactly that. Crawl-space and basement construction both appear here, varying by proximity to the coast and water table. Combined with Richwood's climate — a humid subtropical-leaning climate with hot, humid summers and winters milder than northern New Jersey, moderated near the coast — 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.
