Meal worms is easy. Just put a bunch of them in a container with dry earth and lots of stale and hard bread and meal. Put them inside there and forget about them ( except for giving them bread and meal). Ensure that absolutely no moisture gets in the container.100% dryness. I allways have production of these guys.
In relation to the Superworms (zoophobas )I am giving you what is given to me: need to be placed individually in containers ( ancient photo film containers( drill holes in it ) or a piece of wood full of drilled holes where each worm can put put herself. It will, eventually, turn into a bug. those bugs mate and there you go...( keep plenty meal on hand in the system ).
I know guys who do this (and just phoned to confirm )
Any doubt, raise your hand, I'll ask again
