I think I may have found a solution to pickle worm . I liveun zone 7 ,last year I planted spaghetti squash away from other squash and cuke. The spaghetti squash got picklworms.but the other squash and cukes didn't. I had planted dill and lemon balm around the other squash but not around my spaghetti. The spaghetti got pickle worm the others didn't. This year I planted them all around my dill and lemon balm, NO PICKLEWORMS YET its July 14th in Atlanta Ga zone7 .hoping this works
