Superworm in substrate

[FJrocks003]

A few weeks ago I added some wood from my superworm breeding tank into the crab tank and you can see where this is going... I didn't clean it well enough and now I have a large amount of superworm in the sand living in the crab tank. I have a large tank with over a foot of sand and at least 3-4 molters at all times do a full clean out isn't really an option. So are these harmful? Should I be worried about them getting to the molters or do I just let them do their thing? I've been picking out the ones I find on the surface but it's not to effective, there seem to be at least 3 or 4 baby superworms every inch at the surface which I feel like will get out of control when they get big, any advice?

Keep pulling them as you find them, at the very least once they pupate into beetles. They can and will reproduce in moist substrate! I haven't brought a superworm into my house in three years and I'm still finding new larvae in two of my gecko tanks.
