Root Away Root Destroyer from UTILITY is used for the prevention and control of roots in sewer lines. Root Away is offered in unique individual water-soluble packets that eliminate the need for messy handling, the guesswork of measuring and the inconvenience of cleaning up. Root Away has a delayed action that slowly releases its chemical crystals to the fibrous hair tree roots where it is absorbed. Root Away is harmless to drainage lines, sewage disposal systems and trees, and is registered with the Environmental Protection Agency. For best results, Root Away should be introduced in the early spring and then used as a monthly maintenance program.UTILITY.
