I too have had nightmares with mites like you describe, like been said they search for high ground so hang upsidedown, get as much off by hand as possible I used damp papertowels and they wont stick around once dry, no more food once dry. But clean the shit out of your room with bleach and make sure to clean your dry room the same and dont start a new flower cycle till you clean up, if you have plants in veg they ARE infested and you will need to deal with that as well. Remember if you are in a room with mites YOU have mites on YOU and you will infect rooms you go into before you clean or change your clothes.
Lots of mite products out there from total organic to nuclear, personally, if I was in your shoes I'd start with nuclear shit get everthing clean and then work your reg maintainace into a more organic regime. knock them out with strong shit then if you keep on top of it the weeker more organic stuff will work good to keep them away.
