I just saw this from that article link you posted about the mite life cycle, I also have my rodents in my snake room so I have to be careful they don't get any provent a mite on them if I decide to use that stuff.
" Rodents that have been treated with insecticides for mite infestations can be highly toxic to snakes."
Now that I'm using paper towels instead of aspen bedding I'm going through my rack twice a day instead of weekly and changing it out when the snakes mess on it. Gives me the chance to spray down the tub for mites and to keep a better eye on my snakes.
