I had a similar problem when my Pixie frog was small until I found the trick. Mine would eat one or two Dubai Roach's or Crickets and that was it. I started putting my Pixie frog in his eating bin with about 10 to 15 Dubai Roach's or Crickets and putting the cover on it and putting him on a semi dark shelf in my pet room and then coming back in about ten or fifteen minutes and all insects were gone. That's the only way I feed mine now and he does eat like a pig. He is a private eater, or a shy eater.
