I had bad experience with meal worms also. My beardie ate 3 of them one night as a different treat. She threw them back up within 30 min's. I didn't try any more for the longest time. Just the other day I got some wax worms because I heard that they were better than meal worms because they do not have that hard shell. I'm not sure on Knob tails or anything because I've never owned one, but she held down wax worms. Now she gets one or two of them every so many days. She seems to love them.
I really hope that it worked out for you! Keep us updated on the process.
