Cockroaches need three things to establish a colony: food, water, and warmth. Millburn's housing stock gives them exactly that. Historic brick and frame two- and three-family homes make up much of the older housing stock, alongside newer suburban development. Combined with Millburn's climate — a climate shaped by the region's proximity to the coast and the New York City urban heat island, with genuine seasonal extremes — 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.
