Unless you live in Antarctica or in an extremely dry climate, there is probably no practical way to completely rid your home of dust mites. But you can take action to lessen their effects. Having dust mites doesn't mean that your house isn't clean. In most areas of the world, these creatures are in every house, no matter how immaculate. But it is true that keeping your home as free of dust as possible can lessen dust mite allergy.
Studies show that more dust mites live in the bedroom than anywhere else in the home.
So to attack the problem of dust mite allergy, the bedroom is the best place to start. Unfortunately, vacuuming is not enough to remove mites and mite waste. Up to 95 percent of mites may remain after vacuuming, because they live deep inside the stuffing of sofas, chairs, mattresses, pillows and carpeting. The first and most important step to reduce dust mites is to cover mattresses and pillows in zippered dust-proof covers. These covers are made of a material with pores too small to let dust mites and their waste product through and are called allergen-impermeable.
