I have no reason to think I have mites, but have been wondering if I can take advantage of current below freezing temps. to make sure. When cleaning my bins, water dishes, accessories etc, can I assume that if I wash and dry them, then put them outside for a few hours when temps. are in the 8 degrees F. range, that any mites will not survive? Would it also be smart to leave freshly purchased aspen shavings etc. in the car overnight to achieve the same purpose?
