Cockroaches need three things to establish a colony: food, water, and warmth. Costilla's housing stock gives them exactly that. A blend of historic Hispanic land-grant village homes and newer mountain-style construction throughout this high country. Combined with Costilla's climate — a high-mountain climate with cold, snowy winters and mild, short summers, far colder than the Albuquerque valley below — indoor cockroach pressure rarely lets up on its own.
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.
