Avid kills mites dead. I would only use it on plants that are in veg. But it will kill them permanently. All the other remedies that were mentioned here did not work for me. I had way too much ventilation in my room for the no pest strips to work. Avid is a continual miticide. So it will kill when you spray and continue to kill for a couple months. So once again, this is not natural and if you are concerned about the chemical route do not use this. If you get tired of having mites, this will get rid of them completely.
