Dust Mites

Dust mites are tiny bugs that like to live in warm, humid environments. They are often found in carpeting, mattresses, bedding, and upholstered furniture. The source of the allergic reaction is thought to be chitin and an enzyme shed in the mite's feces. Chitin is a substance that composes most of the insect's body. The chitin and the enzyme mix with dust and become airborne. If an individual who is allergic breathes this contaminated dust, a reaction occurs. Symptoms of a dust mite allergy are similar to those of allergic rhinitis, including a runny nose and sneezing, and the eyes may water profusely as well. Other symptoms may be present, such as postnasal drip and sinus pressure. The nose and roof of the mouth may itch.

Dust mites can worsen asthma symptoms as well and may also lead to sinus infections. A dust mite allergy is more common in children and young adults. Individuals with this allergy should wash their bedding frequently in hot water and have carpets and furniture cleaned regularly.
