What does “trenching” mean on the Ortho Home Defense MAX Termite & Destructive Bug Killer label?
Chemicals for soil treatment are used to establish a barrier against termites. The product must be adequately dispersed in the soil to provide a barrier between the wood in the structure and the termite colonies in the soil. Barriers may be established in the soil on the outside perimeter of the house by trenching. Follow label directions for the appropriate way to use Ortho Home Defense MAX Termite & Destructive Bug Killer as a trenching treatment*.
