Most of them don't really for whatever reason, unless they're in there a while. I use a really small feeder cup, it's a easy mac container with half a party cup glued to it with screen inside so the bugs can crawl. My male has a tongue injury from when he was a baby and can't shoot his tongue out very far and has horrific aim, and he does best when he can get right up on the food. I can dump like ten crickets in there and most of them just crawl around on the screen. One or two jump out if it takes him a while to get there but otherwise for the most part they kindof just chill. Using an average sized deli-cup or tupperware container is totally sufficient to keep them from jumping out.
