I have mine in a Rubbermaid tub. I use oat bran as base. We feed ours cut up potatoes and carrots. I will gut load them with old fruit. If you keep them cool it slows down the change to beetle. I have a container for worms, beetles, and aliens. If I get a bumper crop I take some with bran and put in container with a lid and place in refrigerator and they will last a couple of weeks. If you take them out every so often let them warm up and feed them and put back in they will last even longer. I find they are very easy and then you know what is in their bellies when feeding them to hedgies.
