House Dust Mites

House dust mites (Dermatophagoides species) are common in the environment and feed on human and animal dander. They are practically invisible to the unaided eye at only 0.2-0.3 mm in length.

They thrive in dark, warm (68-77 degrees F), humid (70-80% humidity) environments like carpets, bedding, and stuffed toys.

Allergies to their body parts and waste are extremely common environmental allergens in pets and people. For pets with diagnosed allergies to dust mites, an allergy vaccine can be formulated to reduce the severity, but environmental control is still extremely important.

Elimination of dust mites is impossible so control measures are aimed at inhibiting mite multiplication and minimizing their numbers in the environment. Ideally the entire household is incorporated in a control program. If that is not possible, at a minimum, pet sleeping areas should be maintained according to the following guidelines:

1. Wash bedding (human and pet) and soft toys weekly. Dry in full heat for at least 20 minutes

2. Avoid feather and wool bedding (or any material not easily laundered) and use allergen-proof bed covers and encase box springs in vinyl or plastic covers

3. Minimize clutter where dust can collect

4. Change HVAC filters in your house regularly. If possible, use filters made for allergen control

5. Vacuum and dust regularly preferably while your pet is out of the room. Ideally, use a vacuum with a HEPA

filter or double-layered micro-filter bag.

6. Use a damp or oiled rag or microfiber cloth to dust rather than dry dusting which can stir up mite particles

7. Groom your pet regularly
