Just saw on this thread on the ATP newsletter and wanted to tell you that Plantskydd is some wonderful stuff! I spray it on maybe twice during the first month of spring and it works excellent. We live right across the street from a nature park and have lots of deer. Once dry it doesn't wash off either. For the first time this year I used the Plantskydd granules for rabbits and it works just as well.
Wishing you good luck - I know how disappointing that is.
