How wiggly are repti-worms? Ali has a hard time seeing so unless something really wiggles he won't see it. I also have a collared lizard who prefers mealworms to anything else (not good) and I'd like to get some for him but again, unless it really wiggles around he ignores it.
Repti-worms/Black Soldier fly Grubs have always been the "wiggliest" feeders worm out there(http://www.youtube.com/watch?v=A6lLnzqt8wk). It might have something to do with its relatively small size.
Dont forget to get the largest size because they tend to be really small. I have a baby beardie that eats the largest size available and hes only 8 inches. Theyre so small that my dragon eats about a hundred a day.
