Good point. Here is another bug angle. If testing proves dust mites are rubbed out, that will be great. To my knolage everyone has them. To my knolage harmless tiny bugs that live off our dead skin cells. Show a TV commercial grafic of dust mites crawling around a bed, "your bed!" Offer a one time reduced rate for a general purpose sanitation/ dust mite service. People will "feel" their skin crawl, the office phone will ring... JMHO
