Cockroaches need three things to establish a colony: food, water, and warmth. Guston's housing stock gives them exactly that. A blend of established rural communities and newer suburban construction expanding from the Louisville metro. Combined with Guston's climate — a humid climate with a long summer season and winters that bring real, if not extreme, cold — 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.
