The set up is this thing:

all you do is throw in your food scraps and viola, soldier grubs. The thing is really amazing. Also, after it has been in operation for a while, you drain off the "tea" and dilute it and use it as fertilizer. Win-win if I ever heard of one.

BTW, there is pretty much no smell. The scent that comes off of it is kind of an earthy smell, not rotting food. I was really skeptical at first, but now I'm going to keep this thing going year after year.
