German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Witts Springs's a climate shaped by both humidity and elevation — warm, humid summers give way to real winter cold in the surrounding hills keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. Housing here ranges from established in-town homes to newer builds on wooded hillside lots, many with basements unlike flatland Delta construction.
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.
