Cockroaches need three things to establish a colony: food, water, and warmth. Compton's housing stock gives them exactly that. A mix of mid-century stucco homes and newer suburban tract construction, most on slab foundations with minimal need for winter-focused design. Combined with Compton's climate — a dry-summer subtropical climate, warmer inland and cooler right along the coast — 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.
