Okay so I had been out of crickets for about five days so I would look for stuff out side to feed my exclamans. It would never be enough and some times they wouldnt even acknowledge it was there. So finally my dad brought crickets home. I put 4 crix in there and that was the most violent wasp hunt I had ever seen. When they had caught them and brought them up to the nest the other wasps would try to steal the cricket from the other wasp and they ended up ripping it apart.
Sorry for TMI but hey, just thought id share.
