Dust Mites
About dust mites and asthma
Dust mites are tiny bugs that are too small to see. Every home has dust mites. They feed on human skin flakes and are found in mattresses, pillows, carpets, upholstered furniture, bedcovers, clothes, stuffed toys and fabric and fabric-covered items.
Body parts and droppings from dust mites can trigger asthma in individuals with allergies to dust mites. Exposure to dust mites can cause asthma in children who have not previously exhibited asthma symptoms.
Actions you can take
- Wash bedding in hot water once a week. Dry completely.
- Use dust proof covers on pillows and mattresses.
- Vacuum carpets and furniture every week.
- Choose stuffed toys that you can wash. Wash stuffed toys in hot water. Dry completely before your child plays with the toy.
Common house dust may also contain asthma triggers. These simple steps can help:
- Dust often with a damp cloth.
- Vacuum carpet and fabric-covered furniture to reduce dust build-up using a high efficiency (HEPA) filter. People with asthma or allergies should leave the area being vacuumed. Read more about Air Filters - Available Guide for Their Comparison.
