Dust mites are not visible to the human eye, but under a microscope they look a lot like spiders. They like to live in dark, warm, and humid places, which is why they are often found in bedding and carpets, and feed on dead skin. While some people do not experience problems with dust mites, around 80% of the US population is allergic to dust mites. Symptoms can be minor, but for some people, they can cause significant problems like itchy and watery eyes, sneezing, coughing, wheezing, and nasal congestion. If you are one of the many people affected by a dust mite allergy, this guide outlines how you can cope with your allergy symptoms and minimize your exposure to dust mites in the home.
