Well, I used to keep 2 Leo's when I was growing up. I'd buy 150-200 or so at a time and keep them in a plastic garbage can (the kind with a lid) in my garrage. Put some big sheets of egg carton material in there and then I just put a little plastic tupperware lid in the bottom that had food and vitamins for the crickets. I'd scoop up however many I was going to feed and dust them in a plastic baggy and then toss them in with Spot (my male) and Dot (my female).
