If you could find something to attract the mites to it, you could then toss THAT out.
Say for instance, I have heard that snails in a pond like lettuce, so if you float some lettuce in there for a few hours, the snails collect on it, and then you just toss it out. So if you find some leaves or another plant to attract the mites to, you may be able to at least control them that way.
