Q. What are dust mites allergies?

A. Dust mite allergy is a response to a microscopic organism that lives in the dust that is found in all dwellings and workplaces. Dust mite allergens, perhaps the most common cause of perennial allergic rhinitis, usually produce symptoms similar to pollen allergy and can also trigger asthma.

Mites are a member of the arachnid family, which includes spiders, chiggers, and ticks. Dust mites are 8-legged spider-like creatures that are about 1/3 of a millimeter in length. There are two species belonging to the genus Dermatophagoides, which are commonly found in North America. Both species feed on human skin, pollen, fungi, bacteria, and animal dander. The food consumption and development of the mites increases with higher relative humidities (70 to 80%) and common indoor temperatures (75 to 80 degrees Fahrenheit).

Dust mites and their droppings are known allergens. It is a protein in the mites and their feces to which people develop an allergic response. When these droppings come in contact with the skin or are inhaled they may cause allergy, asthma, and/or eczema symptoms. A gram of house dust may contain 100 to 500 mites, and each mite produces 10 to 20 waste particles a day. This waste is extremely tiny and light, and thus is easily aerosolized.

Q. How does one control dust mites?

A. Although virtually no environments are free of dust mites there are steps that can be taken to reduce their numbers including:

Encase mattresses, box springs, and pillows in non-allergenic, plastic zippered encasings.
Avoid down and feather bedding materials and wash bedding frequently in hot water (over 159 degrees Fahrenheit).
Avoid upholstered furniture when possible.
Avoid carpeting when possible or use a low pile carpet. Wash scatter rugs frequently.
Dust and vacuum twice a week using a vacuum with HEPA filtration or a central vacuum that vents particles to the outside of the house.
Keep humidity below 50%, ideally between 30-40%.
Frequently change HVAC filters and, if possible, use a HEPA air cleaner.
Discourage pets from bedrooms

Q. How can I tell if I am allergic to dust mites?
A. Only certain people will develop an allergy to dust mites and their feces. These people can be identified by means of a skin prick test (SPT) or RAST tests done on a blood sample.
Desensitization injections (Systemic Immunotherapy – SIT) may be used to treat pure house dust mite allergy that fails to respond to avoidance measures or common medical therapy.
Indoor allergen analyses for dust mites (Mite Der p 1, Der f 1) is available using the ELISA method for analyzing dust samples.

Incidentally, if you want to keep dust mites at bay this summer, a dehumidifier or air conditioning is a must. Dust mites do not thrive in dry air. We have a particularly high grade dehumidifier by Ebac, the people who design "dry rooms" for businesses. See all the Ebac dehumidifiers in our Store.
