Dust mites come about naturally and can find a home in any residence. They are not parasites, but pests that produce substances that trigger allergic reactions and asthma. Dust mites feed on dead human skin cells found in dust particles.
A larger number of dust mites may be present when humidity is high. Dust mites absorb moisture from the air and cannot survive in low humidity. Dust mites can live in many places in a household, including carpeting, bedding, mattresses and furniture. To eliminate dust mites, reduce humidity, mop floors frequently, remove carpets or clean them with benzyl benzoate, and wash bedding in hot water.
