1, often ventilated. Mites like damp, high temperature, cotton and linen fabrics and dusty environment, the temperature is 2 ~ 25℃ and the relative humidity is 65% ~ 8%, which is very suitable for the development and reproduction of dust mites. So dryness and frequent ventilation are the weapons to destroy them. Be sure to open doors and windows frequently, insist on ventilation and light transmission, especially when using air conditioning, pay more attention to indoor ventilation.

2. Wash clothes frequently. Always wash clothes and dust, and wash bedding with hot water at about 5℃ every two weeks. Try to simplify the layout of the bedroom to facilitate dust removal, do not lay carpets indoors, and do not put tapestries and other things that are easy to accumulate dust at home.

3. "Wet operation" cleaning method. Mites and their excrement hidden in beds and sofas may fly in the air when tidying up the room, and then be inhaled into the bronchi, which may easily cause obvious allergic symptoms. When cleaning, be sure to use a wet rag or a special mite-removing rag to form the habit of "wet work".
