Dwarf Weeping Willow Beetles: Orthene or Soil Systemic

Weeping willow infested 2 yrs: dark greenish-blue beetle and tiny black multi-legged bugs eating leaves. Sevin failed.

Better Control

Foliar spray acephate (Orthene)—thorough coverage, longer residual than Sevin.
If too large to spray: soil-applied imidacloprid (Bayer Advanced Tree & Shrub Insect Control).

Spray Orthene on all foliage. Or drench imidacloprid. Sevin is weak; Orthene works.
