This is in michigan in the lower penn; near toledo. I have these web looking pouches, i believe they are from gypsy moths,? climbing hardwood trees and defolliating the branches with these caccoons. it is to late to wrap burlap around the trunk and get them that way, I f you have an idea on how; getting those that are way, way up, in the tree please enlighten me. I have heard a power washer with soap might do this [kill the thousands of larvae that are in these pouchs] but i'm not sure of this. If you know of something. Or, can help me out with a better way do rid my trees of this pest, please let me know, i need the help. my trees seem to be the only ones thats loaded this year. trees are walnuts.
