    How is dust mite allergy diagnosed?

    • Your child’s healthcare provider will ask you questions about your child’s symptoms and exposures and perform a physical exam.  
    • If your child’s doctor suspects an allergy to dust mite, they might refer your child to an allergy specialist. The specialist might suggest a skin or blood test to check for this allergy.  
     
     

    How can I prevent symptoms from dust mite allergy?

    • Encase pillows, mattress, and box spring in “allergen-impermeable” or “dust-proof” covers.  
    • Use washable bedding. Wash all bedding in hot water (at least 130°F) every week.
    • If possible, replace the carpet in your child’s bedroom with a hard, wipeable flooring material.  
    • Use washable throw rugs and wash them every 2 weeks in hot water.  
    • Vacuum all carpet at least once per week, preferably with a HEPA-grade vacuum cleaner.
    • Remove other non-washable items from your child’s bedroom. This includes stuffed animals, throw pillows, upholstered furniture, and curtains.
    • Keep the humidity in your home below 50%.
    • Allergy symptoms often worsen during or immediately after vacuuming, sweeping, and dusting. The process of cleaning can stir up dust particles, making them easier to inhale. CERTIFIED filter vacuum cleaners can help to keep mites and mite waste from getting back into the air. 
     
     

    How is dust mite allergy treated?

    • Treatment is focused on minimizing symptoms.  
    • Common treatments include:
    • If your child’s symptoms are not adequately controlled, the allergy specialist might recommend “allergy shots” or immunotherapy.  
     
     

    When to call your doctor:

    • Your child has fever with their allergy symptoms.  
    • Your child is having difficulty breathing.  
    • Your child is getting worse.
    • You have other questions or concerns.
