Dust mite bodies and fecal pellets are the major source of allergens in house dust. [1, 2] More than 80% of homes in the United States and 85% of day care facilities have detectable levels of dust mite allergens [3] ; half of US homes have levels higher than the proposed threshold levels for sensitization, and about 25% have levels at or higher than those required to induce asthma.
