Dust Mite Facts
If you are reading this page, chances are you or someone in your family has
been diagnosed with dust mite allergy. The allergens originating from dust mites
are the world's second greatest cause of allergies, behind pollen, and are
significant triggers of asthma attacks.
Estimates are that as high as fifteen to
twenty percent of the earth’s total population is allergic to the allergens
produced by dust mites. Dust mites are microscopic creatures that are the second
leading cause of allergy, behind pollen.
There are two dust mites: Dermatophagoides farinae is the North
American house dust mite and Dermatophagoides pteronyssinus is the
European dust mite.
Dust mites are most closely related to spiders and ticks. They have eight
hairy legs, no eyes, no antennae, a mouthpart group in front of the body) and a
tough, translucent shell. These mites are about 250 – 300 microns in size and
cannot be seen without magnification.
Adult dust mites live for about a month and female dust mites live for about
8 to 10 weeks. The female lays eggs singly or in small groups. From egg to adult
takes about 3 to 4 weeks.
If humans or pets live in your house, you have dust mites. No special test is
needed to check, it is a fact.
Dust mites collect, live, and breed where food is readily available. The dust
mite feeds on shed human and animal skin cells. However, if necessary dust mites
will feed on fish food flakes, pet food kibble, fungi, and cereal crumbs.
Since fiber-filled surfaces collect the most dust mite food, they have the
highest concentrations of dust mites and their waste products. Dust mites are
most at homes in mattresses (it doesn’t matter if it is a conventional or some
special foam mattress), pillows, box springs, blankets, sheets, upholstered
furniture, rugs, carpets, draperies, curtains, sheets, decorative fabric panels
and tapestries hung on walls, pet beds, as well as the interiors of automobiles.
They like it dark, warm and moist.
Ohio State University reports that a typical used mattress may contain
100,000 to 10 million mites inside. Ten percent of the weight of a two year old
pillow can be composed of dead mites and their droppings! Gross!
Over their life span, the mite will produce hundreds of fecal pellets. It is
a protein in the fecal pellets that cause allergic reactions in humans. In
addition, as the mite grows, it sheds its exoskeletons and this also contains
the protein that causes allergy.
Dust mites do not bite you. You can not feel them crawling on you. The
allergic symptoms are caused by inhaling the microscopic fecal matter and shed
skins. Symptoms of dust mite allergy include but are not limited to respiratory
such as sneezing, runny nose, stuffy nose, cough, difficulty breathing, and
asthma. In addition, skin symptoms such as eczema and dermatitis can result.
Rashes and hives are rarely a symptom of dust mite allergy.
There are no pesticides currently labeled in the United States for the
treatment of dust mites. In fact it does little good to actually kill dust
mites, as dead dust mites bodies still contain the problem causing protein and
killing dust mites does nothing to remove the fecal matter. However, benzyl
benzoate and tannic acid have been shown to be effective in laboratory and field
tests. Benzyl benzoate is one of the active ingredients in De-Mite and tannic
acid is the active ingredient in X-Mite powder and ADS spray.
Dust mite control is all about controlling the places dust mites congregate.
The fewer fiber-filled surfaces in a room or a house the fewer places for the
dust mites to set up housekeeping. The most common recommendations are to use
vinyl, wood, or other hard surface blinds instead of curtains or draperies;
remove all carpeting and rugs and use wood, vinyl, or tile flooring; replace all
fabric upholstered furniture with leather upholstered furniture and remove all
books, lamps, knick-knacks and dust catching items from a room. However, no one
wants to live in a bare bubble. So what can be done?
Effective dust mite control can be achieved by taking the following steps:
Keep only one bed in the bedroom. Most important,
encase the box springs, mattress, pillows and duvets in a
dust mite mattress cover
(zippered encasement). If a second bed must
be in the room, prepare it in the same manner.
Use only washable materials on the bed. Sheets, blankets, and other
bedclothes should be washed weekly in water that is at least 130EF. Lower
temperatures will not kill dust mites. If you set your hot water temperature
to a lower value (which is commonly done to prevent children from scalding
themselves), wash items with
allergen control products like
De-Mite Or Allersearch Allerwash specially designed products that kill dust
mite allergens in warm and cold water.
Keep all animals with fur or feathers out of the
room. People allergic to dust mites often are allergic to cats, dogs, or
other animals. If you can't, treat the pet with
pet friendly allergy control products.
If the dust-sensitive person is a child, keep
toys out of the bedroom that will accumulate dust. Use
washable asthma friendly
is possible or toys of wood, rubber, metal, or plastic, and store them in a
closed toy box or chest.
Carpeting makes dust
control impossible. Although deep pile carpets are the worst type for the
dust-sensitive person, all carpets trap dust. Therefore, hardwood, tile, or
linoleum floors are preferred. Treating carpets with
X-Mite a tannic acid based products eliminates dust mite
allergen, but tannic acid is not as effective as removing the carpet, it is
irritating to some people, and must be reapplied every 90 days.
Dust mites absorb
water from the environment and from their food source. A dehumidifer may be
helpful because house mites require high humidity to live and grow. Care
should be taken to clean the unit frequently to prevent mold growth.
However, while low humidity may reduce dust mite levels, it also may
irritate the nose and lungs of some people
It is impossible to rid your home of dust mites, but by taking these steps,
you can reduce your exposure thereby reducing your allergic reactions. Also
remember that having dust mites is not a refection of how you keep your house.
Dust mites are found in the finest homes and hotels across the globe.
