I just googled what to do and found this
There very dangerous. But don't blame urself, I didn't know either. Mine ate one on Thursday & iv had some very late nights with him recently. He's just now able to hold his head up & he a a meal worm this morning. At first I had no idea what to do & EVERYONE told me he would die & I couldn't stop it. But I kept him in a warm
bath until saturday when I got more advice. The advice was mineral oil & electrolytes. I got the oil in the digestive aid area, & pedialite. I couldn't find pedialite so I used sobe with electrolytes. & he like it more than the gatoraid. Soak him in the electrolytes & keep it warm, keep him under proper lighting & give him a small amount of oil through a dropper or syringe.
This may be worth a try????
