You should be watching certain evergreens and garden plants for spider mites this summer.
Damage is identified by yellowish to rust color of the foliage.
Presence of mites can be detected by tapping branches over a white piece of paper. Numerous small specks should be noticed crawling on the paper if you have spider mites. First injury is normally near buildings or in warmer locations. Dry, warm weather hastens development. Spraying twice with a miticide 10 days apart will stop spider mites.
