Why don't we let Anthony let us know what he thinks about mealworms???
if you need something when crickets are hard to find there is always the cgd option (probably the best food you can give them anyway)

Can Crested Geckos eat mealworms?
I wouldn't say that they can't eat them, but that it's not worth the effort. Mealworms are of little nutritional value and are difficult for lizards to digest, therefore I don't see any reason to feed them to Crested Geckos. If you just happen to have extra meal worms and want to feed them off, go for it. However, I wouldn't go out of my way to get them. The main problem is that mealworms move slowly, so many times they go unnoticed. If left in there too long, they will pupate and turn into beetles, which you'll then have the pleasure of removing.
All in all, feeding live prey is a hassle no matter how you slice it. Meal worms may be convenient (you can throw them in the fridge), but they simply aren't an ideal food for Crested Geckos.
I see a lot of young keepers that want to feed live prey, but they have a mom or dad with an aversion to crickets. For those keepers, I think you would be better sticking primarily with Crested Gecko Diet. When and if possible, just pick up a dozen crickets from the pet store and feed them off in one day. Even one cricket meal per week, just to change things up, can be beneficial. This way, your geckos will still get a treat from time to time and you won't have to worry about keeping crickets in the house.
