People have reported good success with dusting the crickets with CGD. Helps them develop a taste for it.

Also are you leaving the food out for a while? I know many cresties like their food "aged" and won't necessarily eat it the first night. Obviously, watch for signs of mold and the like, but there is some thought this is a throw back to them eating fallen fruit. I know my girl when she was younger wouldn't eat her CGD until is was fruit leather consistency the next night, now she'll eat it fresher, but sometimes still likes it sticky.
