I have given/give some of mine super worms once in awhile. The ones that will eat them. Some will have nothing to do with them though. And some times the ones that will eat them just wont eat them. This is just with my T's anyways. I do crush the heads of the super worms before feeding though so they can't/couldn't bite the T. I know some people chop up meal worms to feed to slings and such also.
