Spider mites are a tiny arachnid that appear like dust under the leaves.
They occur during hot, dry weather. They can be controlled by spraying the
plant every 7-10 days with water to destroy the webs and knock the mites off
the leaves. Be sure to thoroughly cover the underside of the lower leaves.
They can also be controlled with the miticides Avid or Kelthane.
