Cockroaches need three things to establish a colony: food, water, and warmth. East Jordan's housing stock gives them exactly that. A mix of established Grand Rapids-area neighborhoods and more rural, forest-adjacent homes farther north, most with basements built for heavy snow load. Combined with East Jordan's climate — a four-season climate defined by lake-effect weather, colder and snowier than southeast Michigan, especially in the Upper Peninsula — 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.
