Provent-A-Mite or PAM for short is the best mite treatment you can get. If thats not what you are using keep it in mind in the event your current product doesn't work.

Your water bowls and other husbandry equipment should be ok in a 10% bleach solution as long as you rinse out very well. If you can smell the water bowl after it dries and not smell any bleach the you should be ok.
