So I just noticed that i have found 2 dark colours small bugs (my guess is mites) in my racks over a weeks period, all snakes have been quarantines prior to being put in the rack. I think they might have been brought in by clothing or something, how do i go about getting rid of this? Im buying the miteoff from the store today, do i change all the substrate in every tub and put mite off on them? and do i apply it to the snakes as well?

lots of help and opinions needed please and thanks
