A healthy indoor environment is important to you and your family. This includes keeping the air free of biological contaminants, which can cause health problems in your Reston VA home. Scientists call these airborne contaminants bioaerosols.
Bioaerosols are extremely small living organisms or fragments of living things suspended in the air. Dust mites, molds, fungi, spores, pollen, bacteria, viruses, amoebas, fragments of plant materials, and human and pet dander (skin which has been shed) are some examples. They cannot be seen without a magnifying glass or microscope.
Yes. They can cause severe health problems for homeowners in Reston, VA. Some, like viruses and bacteria, cause infections (like a cold or pneumonia). Others cause allergies. Both allergic responses and infections may be serious or even fatal.
An allergic reaction occurs when a substance provokes formation of antibodies in a susceptible person. We call substances which will cause an allergic reaction in some people antigens or allergens. Bioaerosols (mold) may cause allergic reactions on the skin or in the respiratory tract. Rashes, hay fever, asthma (tightness in the chest, difficulty in breathing), and runny noses are common allergic reactions.
A few people develop a severe allergic reaction in the lung, which can destroy lung tissue. This is called hypersensitivity pneumonitis. It is not an infection, but repeated episodes can lead to infections of the lung, such as bacterial pneumonia.
Hypersensitivity pneumonitis can be triggered by exposure to very small amounts of the allergen, once a person is sensitive to it. Symptoms can range from tightness in the chest, cough, and difficulty in breathing, to low-grade fever, muscle aches, and headaches.
Molds, mildews, bacteria, and dust mites like the same conditions that we do--warmth and moderate to high humidity and can be found in homes in Reston VA. They need little more than a constant moisture supply for survival. You may find bacteria, molds, and mildews in air conditioning equipment, humidifier reservoirs, dehumidifier drip pans, shower heads, toilets, and ice machines. Should your Reston VA home suffer from water damaged carpets, ceiling panels, walls, and paneling, you could prime locations for new growth if they are allowed to stay damp. When molds, mildew, dust mites, and bacteria are disrupted or release their spores into the air, this results in bioaerosol formation.
Molds and mildews develop from spores, which are in the air all around you. As soon as spores settle in an area with the right conditions for mold growth, they establish colonies, which are often visible to the naked eye. These colonies are a source of more spores, can cause unsightly stains, and may release low levels of toxic chemicals called mycotoxins into the air.
Humidifiers are such a common source of bioaerosols that cause health problems that doctors now use the term humidifier fever. Protozoa, amoebas, and strains of bacteria have been found in humidifiers, and these are readily released into the air with the moisture produced by humidifiers. These have been linked to allergic responses in sensitive people.
Dust mites and their waste products are the most common allergens in indoor air. Dust mites eat human and pet skin (dander) as it is shed. It has been estimated that we shed about seven million cells per minute! Dust mites live in rugs and carpets, sheets, mattresses and pillows, and upholstered furniture. Ten to 15 percent of people are allergic to dust mites. Of the people who have other allergies, 40 percent are also allergic to dust mites. Dust mites can be a common problem anywhere including your Reston VA residence.
First, lower the relative humidity in your home, basement or crawl space, and attic. Relative humidity is the amount of moisture in the air at a given temperature. You may want to see Identifying and Correcting Moisture Problems in Homes. The humidity fluctuates in your home, depending on:
If you can keep relative humidity below 50 percent, you can reduce problems with dust mites, mold, and mildew. A hygrometer can be used to measure indoor humidity levels. You can buy a hygrometer from some nursery or garden stores, and from hardware stores.
There is little medical research supporting the use of a humidifier, so try to avoid using one. If your home is extremely dry and you must use a humidifier, a steam vaporizer or warm mist humidifier causes fewer problems. Do not humidify indoor air to a relative humidity level higher than 50 percent.
It is not known how well any single measure controls dust mite populations. However, it is known that effective mite control requires that relative humidity be maintained below 50 percent. In addition, since you spend about a third of each day in your bedroom, concentrate your efforts there.

I wanted to thank you again for assisting us in the recent meth case in Strasburg.
Wayne W. Sager
The job was to remove all the old rock-wool insulation and 60-years of dust, bird droppings, and dirt from the attic so that new fiber glass insulation could be installed. Dan's team of workers did a super job in cleaning the attic of all this stuff. I could find nothing remaining between the joist or in corners of the attic. It was so clean that you could have food served on the floor in the attic. They were on-time, completed the work as scheduled, and the work team was professional, organized, and experienced. Highly recommend Envirotex.
