Many spider mites produce webbing, particularly when they occur in high populations. When you see this webbing, you need to jet spray your plant with water on a daily basis. The water will wash off the spider mites and reduce the populations. Eggs that are laid may still be there, so repeat washing will prevent the populations from building up again. Watch all your evergreens and certain garden plants for spider mites this summer.
Damage is identified by yellowish to rust color of evergreen 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.
