|I have numerous spider webs at the ends of the branches of an unknown evergreen which was planted by a previous owner. They surround the growing tip of each branch/twig. What is a safe insecticide for this shrub? Thanks!

|Innocuous spiders will make webs in your evergreen trees and shrubs?but they are not considered harmful to your plants and won?t kill needles they way spider mites do. (Spider mites are usually found towards the inner parts of evergreens.) Try blasting the webs with water in the cool of the morning. The spiders will find other places to live.
