Morioworms safe for leopard gecko cleanup crew?

[i-love-all-reptiles-ever]

I love my little girl so very much, my little leopard gecko. I want her to be safe, not to get hurt. So i'm trying to make an arid bioactive natural looking tank, giving her some extra climbing, hiding, etc. However i'm figuring out the cleanup crew, so far i've figured orange and tropical grey isopods should work. But i've heard that you can use morio worms/superworms. Is this safe? Has anyone had their gecko get hurt by these?

Here's what I've found out: At one time I advocated breeding feeders right there in the cage with the geckos. Most recently I bred morio (super) worms in my gargoyle geckos' cage. At first it went well. Then the beetles started eating the styrofoam background (which would probably not be an issue with a leopard gecko cage). Then the beetles started eating the gargoyles' tails! That was the end of breeding super worms in the enclosure. Even if you don't plan on breeding them, if the super worm gets loose and buries its way into the substrate, it will pupate and turn into a beetle. And then you'll have more super worms . . . and you get the picture. Isopods work, and also, since the enclosure had to be drier than the isopods like, I was using dermastid beetles which look like tiny black beetles (about 1/8" long). That worked well and the only problem is that sometimes the population would get a bit high, but they never ate my geckos!
