However, it is known that effective mite control requires that relative humidity be maintained below 50 percent. In addition, since you spend about a third of each day in your bedroom, concentrate your efforts there. Wash sheets, pillowcases, and mattress covers frequently in hot soapy water. If someone in your family is allergic to dust mites, buy special vinyl covers for the pillow and mattress. Ordinary vacuuming does not remove or reduce mite populations.
Mites are so tiny that they pass through the vacuum cleaner bag.
High-efficiency filters for vacuum cleaners may be used in place of conventional filters. Remove stuffed animals and objects that collect dust. If carpeting is used, short-pile is best. Some new products may help reduce dust mite populations. Ask your doctor about control solutions for upholstered furniture and bedding.
