one little trick i have done with my tarantulas is to take a empty and clean prescription botttle and put several small holes in it (a paper clip heated up will do the trick nicely, or gently with a drill bit). Slime the inside with a mix of honey and vaseline(more vaseline than honey) put the lid back on and place in the cage. it will attract mites and they cannot escape the vaseline. simply throw away when you need to.
