Can you see dust mites without a lens? What do dust mites eat?

Answer 1

No, you cannot see them with out a lens, for me at least 30X My eyesight is bad! and dust mites eat dead skin cells that you and I shed!
So if we were not all allergic to their POOP, then they would actually be doing us a favor to rid our houses of dead dried skin cells.
They are kind of ugly when you do look at them, so I don't advise it if you are prone to night mares

Answer 2

No you cant see them with the naked eye. They eat dead skin cells and dirt.
