Dust mites are very small, insect-like pests that feed on dead human skin cells and thrive in warm, humid settings. Dust mites are too small for us to see. They are not parasites that bite, sting or burrow into our bodies. Instead, people who are allergic to dust or dust mites are reacting to inhaling proteins in dust that comes from dust mite feces, urine or decaying bodies. Any swelling (also called inflammation) of the nasal passages caused by dust mites is considered a dust allergy.
Dust mites occur naturally and can appear in nearly all homes; roughly four our of five homes in the United States have dust mite allergens in at least one bed. Dust mites can live in the bedding, mattresses, upholstered furniture, carpets or curtains.
Humidity is the most important factor in determining whether a house has high levels of dust mites. This is because dust mites do not drink water like we do; they absorb moisture from the air. In areas with low humidity, like deserts, dust mites cannot survive.
Unlike pet allergens, dust mite allergens do not usually stay in the air. Instead, the allergen settles quickly into dust or fabrics. These allergens cling to bedding, mattresses, upholstered furniture, carpets and curtains, which also serve as nests. Most exposure to dust mite allergens occurs while sleeping.
Ongoing exposure to dust mites at home can impact the health of people with asthma and those who are allergic or sensitive to mites. These allergens can trigger mild to severe allergic symptoms and can be responsible for asthma attacks. A mild case may cause an occasional runny nose, watery eyes and sneezing. In severe cases, the condition is ongoing, resulting in persistent sneezing, cough, congestion, facial pressure or even a severe asthma attack. People with asthma who are sensitive to dust mites face an increased risk of asthma attacks.
Home is supposed to be a comforting oasis, but for people with dust allergies the home can trigger uncomfortable symptoms. Oddly enough, allergy symptoms often worsen during or immediately after vacuuming, sweeping and dusting. The process of cleaning can stir up dust particles, making them easier to inhale.
Cockroaches live in all types of buildings and neighborhoods. Some people develop allergy symptoms when they are around cockroaches. Tiny particles from the cockroach are a common component of household dust and may be the true cause of a dust allergy.
Pollen comes from trees, grasses, flowers and weeds. People can be allergic to different types of pollen. For instance, some people are allergic to pollen from only beech trees; others are allergic to pollen from only certain kinds of grasses. Pollen is a common component of household dust and may be the true cause of a dust allergy.
Pets can cause problems for allergic patients in several ways. Their dander (skin flakes), saliva and urine can cause an allergic reaction, especially when combined with household dust. In households with birds, feathers and bird droppings can also become embedded in household dust and cause problems for people who are allergic to them.
If you think you may have an allergy to any of the components of house dust, see an allergist. To pinpoint the cause of your symptoms, the allergist will ask detailed questions about your work and home environments, family medical history, frequency and severity of symptoms and exposure to pets and other possible triggers.
The dust in your home may contain pet hair and dander, mold or pollen spores, and dust mite or cockroach body parts and droppings, all of which are common allergens. These allergens can cause an allergic reaction when you inhale or come into contact with them.
The Dust Bowl was the name given to the drought-stricken southern plains region of the United States, which suffered severe dust storms during a drought in the 1930s. As high winds and choking dust swept the region from Texas to Nebraska, people and livestock were killed and crops failed across the entire region. The Dust Bowl intensified the crushing economic impacts of the Great Depression and drove many farming families on a desperate migration in search of work and better living conditions.
Billowing clouds of dust would darken the sky, sometimes for days at a time. In many places, the dust drifted like snow and residents had to clear it with shovels. Dust worked its way through the cracks of even well-sealed homes, leaving a coating on food, skin and furniture.
The worst dust storm occurred on April 14, 1935. News reports called the event Black Sunday. A wall of blowing sand and dust started in the Oklahoma Panhandle and spread east. As many as three million tons of topsoil are estimated to have blown off the Great Plains during Black Sunday.
On May 1, multiple crashes occurred on I-55 near the Sangamon/Montgomery County line due to blowing dust reducing visibility to near zero. Illinois State Police reported 72 vehicles involved on both sides of the interstate between mile markers 76 and 78. There were seven fatalities, and 37 people were injured.
The satellite imagery below (click image to enlarge) is from the GOES-16 satellite, with the loop created by NOAA's Cooperative Institute for Meteorological Satellite Studies (CIMMS) at the University of Wisconsin. One of the satellite's 1-minute Mesoscale Domain Sectors happened to cover that area, and the loop contains minute by minute images between 11 am and 3 pm. This particular color scheme combines several different wavelength bands to highlight areas of dust. The dust is most noticeable in the pink bands that extend just south of Springfield (station KSPI) to Effingham (station K1H2), over parts of Sangamon, Montgomery, Christian, Shelby, and Effingham Counties. Clouds (shown in the red and greenish-yellow shades) cover up some of the extent of the dust.
The dust originated from freshly tilled and planted farm fields, and was kicked up by wind gusts of 35 to 45 mph. Winds increased further during the day, peaking at 54 mph at the Springfield airport at 3:42 pm.

Very small, fine particles (particulates) may cause more serious health problems because they can be inhaled deep into the lungs and airways. These extremely small particles and liquid droplets can include acids, chemicals, metals, soil or dust.
If you are concerned about your exposure to sand, dust, or particulates, talk to your health care provider or contact your local VA Environmental Health Coordinator to help you get more information from a health care provider.
Although particulate matter (PM) emissions from natural and man-made sources are found worldwide, PM levels in Southwest Asia are naturally higher. Primary sources of PM in Southwest Asia include dust storms, vehicle exhaust, construction sites, farming, and emissions from local industries.
The use of burn pits for waste management increased the naturally high concentrations of PM in Iraq and Afghanistan. Air sampling performed at Joint Base Balad, Iraq (the large Balad burn pit operated there and was shut down in 2009) detected increased particulate matter and infrequently some chemicals, which may have been due to the industry in Iraq.
Symptoms of sand, dust and particulate exposure include irritation of the eyes, nose, throat, and skin. Other symptoms include cold or flu-like symptoms such as cough, runny nose, and shortness of breath. Learn more from the Department of Defense. (83 KB, PDF)
Veterans who were deployed to the Persian Gulf, Afghanistan and similar environments were often exposed to sand, dust, pollution and other airborne particles. PM levels in these locations are naturally higher, and primary sources in this region include dust storms, vehicle exhaust, construction sites, farming, and emissions from local industries.
Windblown dust is dust emitted from loose soils or disturbed natural lands by wind action. Weather conditions, the natural environment, and human activities can cause windblown dust that contributes to air pollution. Various dust control methods are employed across California to control windblown dust, from the coast to the desert, depending on local soil properties, topography, and meteorology.
Windblown dust is a concern for air quality statewide. Anyone exposed to particulate matter can experience adverse health effects, however young children, older adults, and those with respiratory diseases are more likely to be affected. Particles with a diameter of 10 microns or less (PM10) are particles small enough to pass through the throat and nose and enter the lungs. PM10 particles make up a large portion of windblown dust and high PM10 concentrations can be common downwind of loose or disturbed soils during wind events.
The best strategy is to limit your contact with dust and dust mites. To get rid of dust mites in your home, keep their living habits in mind. They prefer temperatures of about 70 F or higher and humidity of 70% to 80%. They can't survive in colder, drier places.
Dust mites like to eat dead skin from pets and humans. You probably shed enough skin a day to feed a million dust mites. Flakes of dead skin in carpeting, beds, and furniture are like tasty snacks for them.

Fugitive dust is particles of soil, ash, coal, minerals, etc., which becomes airborne because of wind or mechanical disturbance. Fugitive dust can be generated from natural causes such as wind or from manmade causes such as unpaved haul roads and operational areas, storage, hauling and handling of aggregate materials, construction activities and demolition activities. Fugitive dust contributes particulate matter (PM) emissions to the atmosphere. PM emissions must be minimized in order to meet National Ambient Air Quality Standards (NAAQS). The regulations described herein are for the following areas of the state:
