When I was younger and lived at home in Michigan on our small farm we would relocate the hornworms into the chicken yard. They would make short work of them I tell ya!
Luckily here in this area, we have a native plant called Sacred Datura; aka Jimson Weed. They have a big flower that you can hardly tell from an Easter lily. I noticed the same worm is on those plants too by accident the other day. Probably because Jimson weed and tomatoes are both nightshades. (altho I never see them on peppers or potatoes) So, I've just been moving hornworms to their new home on Jimson weeds here and there around the property. Maybe I'll regret this, I don't know, next year there will probably be 10 times as many worms.

The moths they come from are so beautiful tho!
