I read that the leaves are what are toxic, not 100% sure though. What you can do is make your own feed for the worms. There is a thread somewhere around here (if you google it, it'll come up) with the recipe for ir.ok since we talking about hornworms ok are they toxic if they only eat the tomato? I know the tomato plant is part of the night shade family and everything i can pull up say both yes and no. I'm doing good with my meal worms and wax worms farms and now going to start up hornworms. I just like to be organic and most important not toxic
Any help will be useful thanks.
