I've heard briefly about them but no experience with: I'd be very cautious about trying them, to be honest. And I don't see why they couldn't "miss a few"
in the same way that the conventional treatments to kill mites do? I can't think of any predators that hit ALL of their targets actually, can you? Because then
they'd perish for lack of food...they'd be out of a job, so to speak. Don't get me wrong, I'm not a fan of "chemical attacks" either, so I hope you get good results.
