I think stink bug damage may be cumulative- they used to not be an issue in my orchard and now 2/3rds of KG are damaged, half are useless. I may try a couple of summer Surround applications next year, but I will not keep poison on the fruit just to assure a harvest. No matter how sweet they are, my 65 year old palate in unimpressed. Liked them much more when I was younger.
