I get 500 at a time and have them in a Rubbermaid tote with a screen in the lid. There is cricket food, cricket water, and egg crates and paper towel tubes. I try to clean it once a week. Is it possible to clean the tote without losing like 50 crickets? My problem is mainly that I want to get out the cricket sheds and dead crickets, but I always lose a lot when I try to clean.
