You can find out quite a bit just by doing of Google search of "raise mealworms."

Here's one I found on how to raise superworms:
www.progeckos.com/caresheets/superworm.htm

And mealworms:
www.sialis.org/raisingmealworms.htm

The main difference between the two is that superworms need to be isolated into their own container (like a babyfood jar) in order to pupate.

I find meal/superworms to be an easy, low maintenance food source. Raising them is kind of fun (though I grew up keeping bugs as pets).
