I agree with Opie 100% When I have Spider mites, and Black gnats raping my girls, I used Strips, and they worked awesome, I also made "Garlic spray" which worked 100% as well. But I found Insecticidal Soap, Neem Oil, and Fruit&vegetable spray works the best. Neem Oil, I had 100% Success on killing the mites, with no returns.
