If you have any plant that mites have taken a particular liking to try moving it if you can. I have fought a monumental battle with mites for over a month and at one point was throwing about everything(except lady bugs) at them only to somewhat control them. They still took a liking to one particular plant and depite heavy soaking with azatrol and the tobacco leaf extract spray, putting in a closet with no pest strips, aerosol sprays etc., that plant remained heavily infested, even spraying with a hose didn't help. When I harvested it yesterday I soaked it in a large tub of water for a while to kill of any mites and hopefully flush out the dead ones.
