Cockroaches need three things to establish a colony: food, water, and warmth. Arco's housing stock gives them exactly that. A blend of older agricultural-area homes and small-town construction spread across this sparsely populated region. Combined with Arco's climate — a humid continental climate with brief, warm summers and long, brutally cold winters, more severe than the Twin Cities the farther north you go — indoor cockroach pressure rarely lets up on its own.
We start with an inspection to identify the species and the source — sanitation issue, moisture problem, or entry point. Treatment centers on gel bait placed in cracks, voids, and under appliances, not broadcast spraying, since German cockroaches in particular have developed resistance to many surface sprays. A follow-up visit confirms the bait is working and the population is dropping.
