Dust mites, those tiny creatures that feed on the skin cells that you shed and produce excrement that is a common allergen, are everywhere. This is incredibly bad news, especially if you suffer from allergens. These vile little pests live in carpets, soft furnishings, carpets, beds and pillows, comforters, or anywhere that is warm and humid. Many people suffer from a dust mite allergy that includes symptoms of sneezing, coughing, itchy skin and eyes at night.
