I am asked all the time if feeding live superworms is safe. Yes, they are very safe. You do not have to cut the heads off superworms before feeding them to your leopard gecko, bearded dragon, or other reptiles. The thought is that if you feed a superworm to an animal without cutting the head off it will eat through the stomach. This is simply not true.
We feed thousands of superworms each year to our bearded dragons, leopard geckos, and other reptiles. We have never had any problems whatsoever.
