Cockroaches need three things to establish a colony: food, water, and warmth. Bodega's housing stock gives them exactly that. A mix of older wood-frame Victorian and mid-century homes and newer high-density construction, most without air conditioning given the mild climate. Combined with Bodega's climate — a temperate climate with minimal seasonal temperature swing, though fog and microclimates vary sharply by neighborhood — 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.
