Cockroaches need three things to establish a colony: food, water, and warmth. Stewartville's housing stock gives them exactly that. A blend of established mid-century suburbs and current new-home construction pushing outward from the Twin Cities. Combined with Stewartville's climate — a climate where winter cold is taken seriously, with sustained snow cover most years from December through March — 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.
