I have so many plants in my cage, that there would be no way I could grab every escapee cricket. It would stress my guys out in a major way. I don't use full grown crickets, because I can't stand the chirping. I usually just put a milk cap full of my gutload mix on the bottom of the cage in the corner. That way the crickets can come down and chew on that instead of my chameleon. So far, it's working, but I do understand that the crickets could decide to go after my chameleons. There aren't too many that get out of the cup, so I think the risk is low.
