AVID is the only way to go. If you want to get rid of mites use avid. After you yield bomb your room, plant new babies and spray them with avid. Spray again right before 12/12. Avid is astemic so when the little shits feed on your crop they die. Igarentee you will never see them again. All the other none chem shit does not work. It may help for a little while but they will be back. It takes 30 days for the avid to be 100% out of the plant so always spray atleast 6 weeks before harvest. I personally wouldn't spray if the plant is flowering.
