I seem to have picked up a grain mite infestation in my confused flour beetle cultures from somewhere. I figure they probably won't hurt the beetles, but I don't want them spreading to my FF medium and cultures. Plus the time when my snakes got snake mites has left me with a loathing for the things. I hate the thought of them crawling on my hands when I handle the cultures. I assume that anything that kills mites without harming FFs won't effect CFBs either. Any suggestions on how to give the 8 legged freeloaders the boot without sacrificing my CFBs?
