I got some to start mealworm breeding a while ago, but I have way too many now. They are healthy and get fresh vegetables every few days and their container is cleaned typically once a week, so no health concerns. I'm not getting rid of all of them though. $5 per 20 of them and I can meet if it's close to me. They're great if you have reptiles and want to breed your own feeders since buying them is quite expensive. They'll come in a small feeder cup so you'll probably want to have a bigger container.
