yes I have, and NO don't use them.
you'll just breed a supermite that is resistant to the miticides, also important to note that it's possibly the reason why the worlds bee population is decreasing at a verrrry alarming rate...
the mites I had before I got the predator mites were IMMUNE to, forbid, avid, azamax, pyrethrin, dichlorvos, and to a degree neem oil.
That's immune, meaning like maybe half would die simply from the physical attack (being dessicated and such) but they didn't even stop em.
150 bucks of predator mites had my plants picked clean in 10 days.
no joke.
and for the record, I was totally a skeptic...
I called bullshit on my buddies claim, he supplies organic strawberry fields all over the pacific northwest.
but he was right.
I was dead wrong, predator mites are badass
