Is it a lot of work?
It's not a lot of work at all. I have a small tub on my kitchen counter. Their bedding is also their food. I use corn meal, they come in bran meal. Which if you want to use you can get in any supermarket around here. Put in a potato or carrot and that's their water source. I check every few days to see if the veggies have gone moldy. Mealworms don't like mold. The beetles don't fly so they can be contained. I got my first beetle last night.
