German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Hidalgo's a hot, humid summer climate with winters mild enough that snow cover is far less consistent than up north keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. Housing spans historic river-town construction to newer suburban development near Springfield and the Metro East.
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.
