Q&A – When and how should I treat crape myrtle bark scale?

Question:
When and how should I treat crape myrtle bark scale?

Answer:
The spring is the best time to treat crape myrtle bark scale. UT Extension Agent Chris Cooper recommends using a soil drench containing the active ingredient imidacloprid or Dinotefuran. One application of imidacloprid will control the scale for a year. Dinotefuran will control the scale for few months. Soil drenches work by applying the product to the soil and the plant takes it up. Any insects that eat the plant get some of the insecticide. If they eat enough, like the scales, they will die.
