Mealworms I put in sterilite bins with the lid off. Get the cheap ones since you don't need a locking lid or much height. I grind non-medicated and diatomaceous earth free chicken feed (check labels) for the bedding in a coffee grinder, a small piece of vegetable for moisture replaced regularly. Waxworms I keep in fridge unless I am breeding them (be careful they can get loose when breeding them, I had some manage to survive in the house for 1 generation much to my surprise.) Butterworms I keep in the fridge but I only have small amounts and they go pretty fast, I haven't tried keeping long term (note: on rare occasion people have experienced minor tissue damage to reptiles correlated with feeding these although no one seems to know why and I've never had this happen myself. I think it must be quite rare). Superworms I keep the same as mealworms. Earthworms I've kept for salamanders and skinks. I used the ones called "European Nightcrawlers". I keep them in moist Cocofiber and feed ground dry foods at the surface. Unfortunately these colonies have a tendency to die out after a few months. It would probably be best to keep two going at a time. They may be a less popular food item and will dry up quickly in most lizard cages, but a lot of amphibians love them and at least a few lizards eat them.
