I'm already using neem. Actually, I think one of the reasons I never got mites in the past was that I was using neem to battle thrips, and as a prophylactic against reinfestation. But I got cocky and stopped when the thrips died, and I'm paying the price now.
And last time I checked, Rotenone is the furthest thing from organic, lol... it stinks kerosene, too.
You can only imagine the stench in my house right now.
