Subterranean termites nest in the soil and access the structure through earth to wood contact, cracks or cold joints in the foundation, and by constructing shelter tubes attached to the footings to gain access. Colonies can and will forage through the soil up to 100 yards from the nest site. Moisture is conducive to infestation and subterranean termites can survive in wet framing without returning to the soil for moisture. Infestation can go undetected for long periods of time. As a result, damage may have already occurred before the infestation is discovered.
Generally, the colony is 3-30 feet below the structure. Wester subterranean termite colonies are fairly large. They average 200,000 and can count into the millions. Behavior is similar to ants as they communicate food location with a pheromone trail. Due to colony size and behavior, a substantial amount of damage can occur in a relatively short time.
We only recommend a complete perimeter soil treatment with Termidor. Other methods (alternative liquids and baits) are substandard in comparison. Termidor (non repellant material) in conjunction with the termites' social behavior leads to complete control within weeks.
