breeding mealworms is ridiculously easy and very low maintenece. However, it can take a while before your colony really takes off. Get a couple of plastic tubs, and a bag of unmedicated chicken feed. (a 50 lb bag only costs a few bucks and it'll take a very long time to use it all up) Put a few inches of feed on one of the tubs and add 100 worms. Use potatos or oranges cut in half for a water source. Leave the covers off of the plastic tubs, the biggest problem you'll have at first is the potatos getting the chicken feed moldy, this wont be a problem later because once you're colony is going well, they'll eat the potatos and oranges too fast for them to start molding. Your original worms will pupate and then turn into beetles and lay eggs. After the beetles have been in there for a few weeks, remove them and set them up in the second tub, otherwise they could eat the baby worms. It'll be a while before you see worms of any size in your first tub.
