Cockroaches need three things to establish a colony: food, water, and warmth. Trevor's housing stock gives them exactly that. Housing here ranges from historic dairy-farm homes to newer lake-country cabins, with basements standard throughout. Combined with Trevor's climate — a continental climate where both summer warmth and severe winter cold define the year, more so in the north than the south — 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.
