ABSTRACT: The effects of various laundry procedures on house dust
mites and their allergens have been established. All mites were killed
by water temperatures 55 degrees C or greater. Killing at lower
temperatures was not enhanced by any of the pure detergents or laundry
products tested. A cold cycle of laundry washing with or without laundry
powder did not remove most live mites from bedding; however, the
allergen concentration (Der p I/gm fine dust) was reduced by more than
90%. Dry cleaning did not reduce the allergen concentration of the dust,
although most, if not all, mites were killed.
