Cockroaches need three things to establish a colony: food, water, and warmth. Kensington's housing stock gives them exactly that. Dense rowhouse and multi-family housing in the urban core, alongside single-family suburban homes further out, most with basements. Combined with Kensington's climate — a four-season climate with real winter cold and snow, and hot, muggy 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.
