German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Big Spring's a dry, sunny climate with genuine winter cold on the High Plains and much milder winters farther south near El Paso keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. Housing spans historic High Plains farming towns to newer development tied to Permian Basin oil activity.
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.
