Termites don't announce themselves the way most pests do. In Trimble, a humid continental climate with hot, humid summers, cold winters, and a real severe-weather season each spring, and Basements are standard here given the region's cold winters and severe-storm exposure. Regular inspection is the only reliable way to catch a colony before it causes real structural damage.
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.
