The pest to look out for this week is the Ash borer or more commonly known as the Lilac Borer.
The ash borer is one of the clearwing moths that resemble a wasp as an adult. They overwinter as late enstar larvae in the wood, usually nearer to the base of the plant. They pupate in the stems and emerge as adults in May/June, roughly. Heavily damaged trees and shrubs should be removed. Preventive bark sprays may help in May and June
