The last 3 years I have had problems with bumble bees, wasps, and flys sucking the juice out of our grapes. They know when they are ready to harvest because thats when they move in and start their harvesting. What can I spray organicly that would keep them away? I have tried seven and liquid seven but have to really clean them good so we aren't taking in any of the chemicals. And even the seven does not keep them away that well.
Thanks for any help.
