German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Lynnville's a humid subtropical climate with hot, muggy summers, mild winters, and high year-round humidity typical of the Mississippi Delta region keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. Housing here is a mix of older farmhouses and Memphis-area suburban homes, with crawl-space foundations especially vulnerable to moisture.
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.
