Probably. I put a potato in my bin that was cut in half. They hollowed the darn thing out - was weird looking! LOL I got some food from greatlakeshornworms - looks like the same stuff they feed their hornworms now. They don't take much, but give them the same moisture like things you'd put in a cricket bin (carrots, potato, apple) - they have enough moisture. I also cover mine with wheat bran but you can use oatmeal too.
