Cockroaches need three things to establish a colony: food, water, and warmth. Apison's housing stock gives them exactly that. A mix of older rural homes built into hillside and hollow terrain and newer suburban construction around Knoxville, with wood-frame construction common. Combined with Apison's climate — a four-season climate shaped by mountainous terrain, with more precipitation and cooler temperatures at elevation — 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.
