Get 3 pyrethrum bombs. Dont waste your money on no Doktor Doom bullshit either. Get the strong stuff called Pyrethrum TR. It is 4.0% pyrethrum vs 0.3% like Doktor Doom. Shut down your exhaust fans/ lights /heaters etc. Blow off the bomb in the room. Its good up to 3000sq ft. Let it sit for about 2 hrs then go in the room and turn on your exhaust and lights like normal. Mix up a batch of neem oil spray (10ml concentrated neem oil + a couple drops of dish soap per gallon of warm water and shake it up real good). The following day after you bomb with pyrethrum, spray your plants with the neem water batch top to bottom underneath the foliage and on the tops until its dripping from the plants. Be sure to give the sprayer a good shake to mix every minute or so of spraying. 3 days after your initial pyrethrum bomb, do this all over again. 7 days after this, blow off the 3rd pyrethrum bomb and you will be bug/pest/mite/mold/mildew/fungus free. This will destroy broad mites. Be sure to do it just like I mention because the broad mite drops its larvae when they get hit with the first bomb. The 2nd bomb on day 3 is to kill off the larvae dropped from bomb 1. The last bomb is just precautionary at worst. Also, pyrethrum is natural and organic and can be used on flowering fruits and veggies up to 4 days before harvest according to manufacturer. The propellant however can burn the plants if it sprays directly all over a plant while going off so set it up on a milk crate or something about 24" or so from any plant material. The fog will move and do its job.
I am speaking from first hand experience as I had been affected badly by them once last year. Key word....once. I follow a strict maintenance program now and have been bug/mildew free for going on a year now.
Heres a pic of how bad I was infested:
