Last summer our walnut, hickory, pecan and persimmon trees were full
of webworms. The second infestation was much worse than the first.
They were really ugly and almost denuded the trees. I've read
someplace that there is a ring that can be placed around trees that
keeps the worms from infesting the trees.

Anyone heard of this? Any other good solutions?
