Cockroaches need three things to establish a colony: food, water, and warmth. Sloughhouse's housing stock gives them exactly that. A mix of older farmworker and agricultural-town housing and newer suburban tract construction, most on slab foundations built for heat rather than cold. Combined with Sloughhouse's climate — a climate defined by extreme summer heat — well over 100°F is common — and cool, foggy winters — 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.
