grape leafhoppers

[4season]

After 25 years they appeared last year. I don't want to spray every few days to kill the newly hatched ones because adults will just fly over from the neighbors. He has enough problems, grapes are the least of his worries. Used the leaf vacuum on them and I think it sucked up a few. Will severely cut back the vines this fall. and spray to kill eggs hidden in the loose bark. Might even prune them properly after that.
