Cockroaches need three things to establish a colony: food, water, and warmth. Sisters's housing stock gives them exactly that. Ranch-style homes dominate this dry landscape, built for cold winters rather than the persistent rain seen west of the Cascades. Combined with Sisters's climate — a semi-arid climate shaped by the Cascade rain shadow, with hot summers and genuinely cold 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.
