Hello, I am growing a grape mix of Texas green and California Concord and these little things have ABSOLUTELY destroyed my crops. How do I kill these filthy pests? I pruned my vines and I sprayed the removed vines with 409 Multi Cleaner and still NOTHING. They’re crawling about and breeding on top of my trash can. P.S. they sting if you touch them and they’re so tiny, they can be anywhere

I didn’t spray the plants. Just the pruned vines to see if it would hurt my plants. Didn’t kill a single caterpillar. They’re eating the foliage and bc of that the plant isn’t getting enough nutrients to produce fruit.
What is bt?
Will this kill the caterpillars or just curb them from eating my plants? I’d prefer not to kill them bc they’re good eats for lizards that eat the bugs off my vines.
It will kill them. You'll have to decide whether the damage to your grapes outweighs the benefit of feeding lizards. I suspect the lizards have other food options.
I certainly hope so, guess today is the day for a good old fashioned murder
