Black vine beetles are a serious pest in Idaho landscapes. Adult beetles chew notches in leaves, but their larvae cause the worst damage—feeding on the roots of trees, shrubs, and perennials until the plant wilts, declines, or dies. If you’re seeing unexplained plant stress, especially in rhododendrons, hydrangeas, hostas, or container plants, black vine beetles may be the culprit. Our Tree & Shrub Drench targets these hidden root‑feeding larvae, protecting your plants from the inside out and stopping the damage before it spreads
