Mites are similar to insects but belong to the spider family. Most common are Spider Mites and Gall Mites. Mites are tiny, almost microscopic, and appear as tiny specks, frequently on the underside of the leaf. Spider Mites damage will be speckling and mottling of the leaf or needle causing the plant to appear grey or washed out and will limit the growth of the plant. Gall Mites will have the presence of the gall, an abnormal growth on the leave, stem or twig. Gall Mites live and feed inside the gall.
