Cockroaches need three things to establish a colony: food, water, and warmth. Melfa's housing stock gives them exactly that. Housing here ranges from centuries-old Richmond-area homes to newer Hampton Roads suburban and military-adjacent construction. Combined with Melfa's climate — a climate shaped by the region's river and bay geography, warmer overall than the mountains to the west — 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.
