Dust mites are common allergens. They live in bedding, carpets, stuffed furniture, old clothing and stuffed toys and feed on human skin scales. An allergic reaction and asthma and/or eczema symptoms result when a person comes in contact with or inhales droppings of dust mites. Keeping a home dust-free is essential if you have a dust mite allergy. Share useful tips, ask for advice, or discuss your experiences.
