Does any one of you find little maggot like worms in your super worms, and very tiny beetles in your meal worms.

I'm not sure if we're talking about the same kind of worms/beetles, but with the crickets that we order to my store as feeders I find little darkish worms and small black beetles too. From what I understand, they are dermestid beetles that eat dead insects, but don't pose a threat to the feeders. I could be wrong though.
