Yup that is an old one.

I breed supers, you need a large tub they seem to prey on each other for moisture and if over crowded. I use oatmeal and cream of wheat substrate I feed greens carrots and bug burger from Repshdy (sp?) they love it. That part is easy to raise beetles I have a separate container a smaller tub and I have a small part container. I will pick out the largest supers and place one each in the divided container. They in a while will turn to crystalists and then beetles. The beetles go in the smaller container and get the same treatment as supers. Keep checking through the substrate for little worms when they start to appear pull the beetles out to a new container and let the worms grow to about an inch then add them to the main. Easy.

I rarely buy anymore every now and again I need to add some yesterday was the first time this year.
