|There are a couple of ways to control the scale insects. You can use Imidacloprid (Bayer Advanced Garden Tree & Shrub Insect Control Concentrate) as a drench around the root zone of infested plants. This water soluble insecticide is taken up by the roots and transported throughout the plant where it is ingested by sap feeding insects. This provides a means of scale control without reliance on sprays. Or you can spray with Bon-Neem or Spectracide? Bug Stop? Multi-Purpose Insect Control Concentrate. Whichever method you use, be sure to follow label directions so you don't harm the leaves on your tree.
