lol, all these fancy fixes....
get some dish detergent (cheapest you can find) and a bottle of neem oil or fruit tree spray (key ingredient HYDROPHOBIC EXTRACT OF NEEM). mix 3tbs of neem + 5 drops or so of dish detergent, and mix with hot water in a 1L spray bottle (fill the bottle 1/5 with hot water, shake). after mixing the soap and neem thoroughly, fill the bottle the rest of the way up with cold water. the solution should then be lukewarm.
the neem oil is a deterrent, and at this concentration, the mites will leave well enough alone. the soap kills them on contact, almost instantly. in addition to killing the living mites, the soap helps to spread the oil over the leaves more thoroughly, providing a better barier. soak bottoms of leaves first, then tops, soak the entire plant til it's dripping. spray every 4 days for at least 2 weeks, to make certain you've broken the reproductive cycle chain.
