Cockroaches need three things to establish a colony: food, water, and warmth. Villa Grande's housing stock gives them exactly that. A mix of older wood-frame homes built into forested terrain and newer construction, most vulnerable to moisture given the persistently wet climate. Combined with Villa Grande's climate — a temperate rainforest climate typical of the redwood coast, wetter and cooler than almost anywhere else in the state — 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.
