Hornworms are great as treats. This has been my experience even though many websites says they can be used as a stable feeder. For me, I tried that and because they have so much water in them (Good for hydration though), my beardie had more watery poop. Not to mention, they can get expensive. If you feed a few a day, it should be fine. But imo, because they carry so much water in them, I prefer to use them as treats instead so try not feed too much in 1 sitting.
