Subterranean termites need soil contact and moisture to thrive, and Grand Coulee's conditions — a climate shaped by the Cascade rain shadow, with real winter cold and hot, dry summers — create exactly that. A mix of older farmhouses and modest small-town homes, most built with basements for winter cold rather than the moisture concerns of western Washington. Termite colonies can go undetected for years, quietly compromising structural wood the entire time.
Termite treatment starts with identifying exactly where the colony is accessing the structure, since a targeted approach is far more effective than a blanket treatment. Depending on the property, we recommend either a liquid soil treatment creating a barrier around the foundation, or a bait-station monitoring system that's checked on a schedule.
