Many people believe that they are allergic to dust, when really they are allergic to microscopic dust mites. These little creatures are unavoidable, but people are able to lessen the symptoms through regular cleaning and other precautions. Those who suffer from the allergy may be interested in exactly what makes up these little creatures.

The entire life cycle of a mite from egg to adult usually lasts for about three to four weeks, and they need to be in warm temperatures in order to survive. There are two different types of house dust mites that are both found in North America. They feed on human skin cells that are constantly shedding. Those who are allergic to dust mites aren't allergic to the actually mite, but their exoskeleton that they shed. Dust mites also feed off of animal dander, so pets can increase the amount of mites in a home.

Dust mites can trigger a wide range of allergies and can also trigger asthma attacks. Those who have trouble sleeping through the night due to these allergies may want to invest in allergy free pillows and a mattress encasement, which can keep allergy symptoms at bay.
