We have a pest guy who comes once a month to spray the property but it seems we cant get rid of these pests. I have caught a few of them in the attached pictures this evening. Some of the trees are ok, others are worse off then before. We purchased them as 3ft trees and the bulk of the 165 that we have are now 6-8ft. A few of them though seem.to have not grown at all so any help there too would be appreciated. Thanks in advance.
