Q.I have something on arborvitae that causes fine webbing all over
I have something on arborvitae that causes fine webbing all over the bush and it dries up and dies. What is it and how do I get rid of it? It’s happened with other types of evergreen bushes.

It sure sounds like a Spider Mite infestation problem. Spraying the shrubs with a good Miticide is highly recommended. Not just a plain insecticide as that just eliminates the Spider Mites natural enemies and makes the infestation worse. Check out these links:
