German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Tres Piedras's a mountain climate shaped by elevation — some towns here sit above 8,500 feet with genuinely severe winters keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. Historic adobe and territorial-style homes are common in the older mountain villages, alongside newer construction built for snow.
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.
