Cockroaches need three things to establish a colony: food, water, and warmth. Ashtabula's housing stock gives them exactly that. Housing here dates heavily to the early-1900s manufacturing and rubber-industry era, with narrow city lots and full basements standard. Combined with Ashtabula's climate — a climate shaped by proximity to Lake Erie, with dramatically higher winter snow totals than the rest 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.
