Next time I would definitely let the wasp covered worm live. However that doesn’t mean it’s gotta stay on your plant. I’d just run it somewhere decently away from the plants such as the other side of the house. That’s natures primary defense against them. Each wasp would probably go on to kill more.

So far I haven’t seen any on mine but my black light came in and I stand ready. I did see a few glowing green small chunks (smaller than a BB) in the dirt of my pepper plant grow bags. Not sure what they were but so far no horn worms.
