Dermatophagoides /-fagoi″dēz/ [Gk, derma + phagein, to eat, eidos, form] , a genus of household dust mite responsible for allergic reactions in sensitive individuals. Protection against the microscopically small mite includes minimizing dust in the home, especially in the bedroom; encasing pillows and mattresses in allergen-proof coverings; controlling temperature; and keeping humidity below 70%.
