Cockroaches need three things to establish a colony: food, water, and warmth. Dravosburg's housing stock gives them exactly that. Housing here dates heavily to the early-1900s steel boom, with narrow lots and full basements standard. Combined with Dravosburg's climate — a climate typical of the upper Ohio Valley, with more cloud cover and lake-effect-adjacent snow than central PA — 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.
