Do not burn nests while the nests are in the tree. The injury from the fire may exceed that caused by the insects. Overwintering scales may be controlled with dormant oil sprays. Control crawlers with Diazinon, malathion, Sevin, or Orthene. To time crawler sprays, identify the specific scale insect.
Spider mites are so small they can cause much foliage discoloration before being detected.
