How to Reduce Dust Mites in Pillows and Bedding

Exposure to dust mites early on can lead to allergies in children.

Dust mites are microscopic insects that feed on dead skin cells shed by humans and pets. Although harmless, some people are sensitive to dust-mite feces and skin castings, and they develop allergy symptoms or asthma. It is especially important to protect infants from dust mites during their first year as exposure may create lifelong sensitivity. Dust mites like a warm, humid environment and thrive in the soft materials such as carpeting, upholstered furniture and bedding. Pillows and bedding provide the perfect habitat for dust mites. You can reduce dust mites in pillows and bedding through preventive measures and regular cleaning.

Things You'll Need

• Dust-mite-proof covers for pillows and mattresses
• Vacuum cleaner with HEPA filter

Instructions

1. Remove and wash all bedding and pillows in hot water. Tumble nonwashable pillows in the dryer on medium or high heat for 10 minutes. Replace nonwashable bedding, if possible, or dry-clean it seasonally.

2. Thoroughly vacuum the top, bottom and sides of the mattress using a vacuum cleaner with a HEPA filter, if possible.

3. Encase clean, dry pillows and the mattress in dust-mite-proof covers.

4. Wash sheets, pillow cases and blankets in hot water once a week.

5. Keep the bedroom temperature below 70 degrees and the relative humidity below 50 percent.

Tips & Warnings

• Place nonwashable bedding in the freezer for 48 hours to kill dust mites.

• Wash stuffed animals regularly.

• Do not allow pets to sleep in the bedroom.
