I have some hornworms that are about 1 and a half inches long and I don't want to feed them anymore because I don't want them to get too big, so my question is about how long will they stay alive if they aren't eating?
Hey I'm surprised nobody has answered this but from what I understand you can put them in the refrigerator to slow them down, on a cycle of 2 days in 1 day out they're supposed to be able to survive quite awhile without growing anymore. At least thats what I've read, I don't have any experience myself.
