Cockroaches need three things to establish a colony: food, water, and warmth. Bayside's housing stock gives them exactly that. A blend of established forest-adjacent communities and newer construction, with moisture management a defining concern. Combined with Bayside's climate — a cool, wet coastal climate with heavy winter rainfall and cool, often foggy summers, unlike the rest of California — 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.
