Hello. If you turn up the fans. The mites can't spin their webs in the wind. You still have them, but they can't move around very well so they don't spread very fast. Please try 50% water and 50% high alcohol. You can use food grade alcohol or isopropanol alcohol and a few squirts of dish soap. Tip the plant if it's in a pot or put a sheet around the roots. If the plant gets too much alcohol on its roots it can look drunk for a few days, sort of limp and tilty. Chuck.
