Subterranean termites need soil contact and moisture to thrive, and The Dalles's conditions — a semi-arid climate shaped by the Cascade rain shadow, with hot summers and genuinely cold winters — create exactly that. Ranch-style homes dominate this dry landscape, built for cold winters rather than the persistent rain seen west of the Cascades. 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.
