Vacuum mattresses and pillows. Wash bedding at 55 degrees centigrade or higher. Detergents and commercial laundry products have no effect on mites unless the water temperature is high. Keep books, stuffed animals, throw rugs and laundry hampers out of the bedroom of allergy sufferers. Wash stuffed animals occasionally in hot water.
Tannic acid neutralizes the allergens in dust mite and animal dander.
Dust problem areas with tannic acid powder, available at health food stores and pet centers. Cover mattress and pillows with laminated covers which prevent penetration by dust mites. Avoid fabric-covered headboards. Cover heating ducts with a filter which can trap tiny dust particles smaller than 10 microns. Avoid using humidifiers.
