German cockroaches favor warm, humid spaces near food and water — kitchens, behind appliances, under sinks — and Laguna's a climate that's desert-dry but far from mild in winter — a wide day-to-night and season-to-season temperature swing defines this plateau region keeps them active most of the year. American cockroaches, larger and reddish-brown, prefer basements, drains, and utility rooms. A mix of older single-family homes and manufactured housing, spread over large distances with lower density than most of the state.
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.
