• Vacuum thoroughly and regularly around the feet of the bed with a HEPA-filter vacuum, triple-layer bag vacuum or a wet mop. Some vacuums and all dry brooms simply stir up and spread the dust mites.

Keep the basement clean and free of the carpets, mattresses and furniture that dust mites love. Also control the basement climate. If all else fails, consider specially formulated dust mite sprays, or acaracides.
