Pine Cone Looking Cocoons Killing Aborvitae
I have several Arborvitae that are dieing because of a cocoon that actually looks very much like part of the shrub. Several of my plants have already died and the others that are still alive have massive amounts of these cocoons. I pulled most of the ones off the ones that are not already dead and squashed them. They are now starting to show up on my Norway Spruce trees also. How do I get rid of these things?
I have read a little and some are calling them bag worms, but they are not what I think of as bag worms. They are not the silky tent like caterpillars that I have always called bag worms. When I was a kid my Dad kept them out of his trees by putting aluminum foil around the base of the tree and they could not climb over the foil. That is not what I have though.
Help before I loose all my bushes!!!
