How to Kill Dust Mites With UV Light
The droppings of dust mites are a leading trigger of asthma. According to Glen Needham, associate professor of entomology at Ohio State University, dust mites, among other bugs, are susceptible to brief exposure to ultraviolet light. The proper frequency range to kill microbes is called "ultraviolet c." Antimicrobial UV lamps use mercury because it emits at 254 nm, which falls in the UV-C range. Does this Spark an idea?

Drag the lump across carpets, cushions and mattresses. Make sure to move the lamp slowly or repeatedly enough to be effective.
Dr. Needham reported in the paper "Ultraviolet C Exposure is Fatal to House Dust Mite Eggs" that exposure of dust mite eggs to UV-C for 5 seconds leads to near 100 percent mortality. Therefore, it is best to stop and hold the lamp in place every inch or so. If a UV-C-equipped vacuum is used, goggles should not be necessary, since the lamp is located out of sight.

Tips & Warnings
Consider using steam to kill dust mites as well. Dry cleaning may be even better, to prevent the mites from becoming airborne.
