Eliminating Dermatophagoides farinae spp. (Acari: Pyroglyphidae) and their allergens through high temperature treatment of textiles.
House dust mite allergens cause allergy and asthma in sensitized individuals. The allergens they produce are known to resist decay under natural household conditions and are thought to accumulate until removed. We sought to evaluate the effects of high temperature (96 degrees C) generated by a hard surface cleaner on live mite populations of American house dust mites, Dermatophagoides farinae Hughes and their allergens in carpet and mattresses. Statistically significant (P < 0.05) mite mortality (100%) was observed in response to treatment in both textile surfaces. Similar effects were observed on Der f1 fecal allergen. Allergen reductions in carpet with two or five pass treatment regimes were 61.4 and 100%, respectively. These results demonstrate the potential of employing a hard surface steam cleaner as a novel method to eliminate house dust mite populations and their allergens in a residential setting and appeal particularly promising as an environmental control strategy.
