I use mine as a dumpster for the leftovers from ones that don't eat. I used to have a burm I used for that purpose so things aren't wasted and he was nice in that he would strike and them down them quickly. My blood instead eats well, but won't strike for the life of her. Leave in the cage, even a few, and they are gone in the morning, but her picky-side is in that she doesn't want to work for her food.
