Dust mites are microscopic arachnids that thrive indoors in warm, moist places, such as the insides of pillows and mattresses. They feed on dead skin that is regularly shed by humans and their pets. The harm posed to building occupants by dust mites is slight compared to other minuscule bed-dwellers, such as bed bugs. Yet, unlike those blood-sucking parasites, dust mites live in virtually every home and in large numbers. Due to their small size, access to copious quantities of food, and an insatiable desire to breed, dust mites can number 100,000 in just one square yard of carpet. They are a known allergen and can create allergic reactions in prone individuals, so it’s important to learn dust-mite detection and population-management strategies.
