From the recent class I took with Gianaclis Caldwell, she indicated that if you have natural rind cheese, you will have mites. So, her approach to control is vacuum rather than blowing. She also felt that taking the cheese to the sink, and giving them a good dry brushing, helps to control the reproduction of the little buggers. She also indicates that the mites do contribute something positive in terms of flavor and aging. Not all bad...
