Dust mites are microscopic spider-related creatures that feed on dead human skin cells and thrive in warm, humid settings, according to the American Lung Association. Dust mites thrive above 60 percent humidity, reproducing quickly and increasing allergen levels. Once humidity drops below 50 percent, reproduction slows. Below 45 percent, populations decline sharply, and sustained levels under 35 to 40 percent make survival difficult for them.
