They have a product called Organicide at Home Depot that works great. I used it once on plants that had webs they were so infested, and they are all gone. It is the only product I have found that works on the eggs.
I mixed like 1oz of Organicide, like 1oz neem oil, and a splash of dish soap, in 1gal of water, and wiped all my leaves with this mix. I rubber gloves and just dipped my fingers in the solution and rubbed all the leaf surfaces, keeping it off the buds. This stuff stinks so do it outside.
You may want to try like 1/2oz of each product the first time as some strains don't like it as much as others and drop some fan leaves. This is the best treatment for mites that I have found. You can also flood your room with Co2 during the dark period. Get it up to like 30,000 ppm of Co2 in your room, and this will help kill the adults, but not the eggs. Like I said, that Organicide is made to kill the eggs as well so it is the best product I can recomend.
