How-to Control Western Subterranean Termites
This is the same as for the eastern subterranean termite. It involves placing a chemical barrier and/or an in-ground monitoring-baiting system between the termite colony and the wood of the structure.
In addition, all wood-to-soil contact should be eliminated, any wood debris must be removed, and the wood moisture content should be reduced to below 20%.
Secondary colonies are controlled by correcting the moisture problem to dry out the moisture-source area. When it is desirable to rapidly reduce the secondary infestation, this can be done by intergallery injection or surface treatment with a pesticide labeled for these termites. Also available are above-ground baiting systems that are placed directly on the infested wood.
