If you want organic then try Diatomaceous Earth, it's a powder, you put a fan in the room and throw some de into it. The resulting cloud will cover everything. The stuff acts like glass shards to the mites and tears their bodies up. If you want to use chemicals then try floramite. It's illegal in some states but you can get it on ebay. That shit will nuke those little fucks dead. All that other stuff that everyone is telling you to try, the mites are going to use it as party favors. Been there, done that. Good luck mans cause mites are a real bitch to deal with if you only take half measures.
