Cockroaches need three things to establish a colony: food, water, and warmth. Ossian's housing stock gives them exactly that. Older brick and wood-frame homes are common throughout this region's historic manufacturing river cities. Combined with Ossian's climate — a climate shaped by the Mississippi River valley, with more consistent precipitation than the drier western part of 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.
