How long can dust mites live

That gives dust mites a lot to eat. Cats and dogs create far more dander for dust mites to eat. A typical mattress can contain tens of thousands of dust mites. Sick yet? Nearly , mites can live in one square yard of carpet.

Ready to convince your spouse to start bathing regularly? Did you know a single dust mite produces about 20 waste droppings each day, each containing a protein to which many people are allergic. The proteins in that combination of feces and shed skin are what cause allergic reactions in humans. Depending on the person and exposure, reactions can range from itchy eyes to asthma attacks. And finally, unlike other types of mites, house dust mites are not parasites, since they only eat dead tissue.

Gross, but true. A typical used mattress may have anywhere from , 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. Mites prefer warm, moist surroundings such as the inside of a mattress when someone is on it.

A favorite food is dander both human and animal skin flakes. About 80 percent of the material seen floating in a sunbeam is actually skin flakes.

Also, bedroom carpeting and household upholstery support high mite populations. The University of Manchester performed a medical study of pillows that found up to 16 species of fungi in a single pillow. They tested feather and synthetic pillows in a range of ages, finding thousands of spores of fungus per gram of pillow ; more than is found on an average used toothbrush.

And just when you thought they were confined to your home and bedroom, there is a news story in USA Today in which Jill Holdsworth is an infection preventionist and president of the DC Metro Chapter of the Association for Professionals in Infection Control and Epidemiology says the car can be another place where dust mites live and a very big place to pass bacteria back and forth if you are not careful, saying "The No.

These areas include the steering wheel, radio, gear shift, cup holders and car seats. For most people, while they are disgusting, house dust mites are not actually harmful. However, the medical significance of house dust mites arises because their microscopic cast skins and feces are a major constituent of house dust that induces allergic reactions in some individuals. There is a genetic predisposition to dust mite allergies, but like many allergies it can also develop over time.

According to Darryl C. In other words, high levels of dust mites and their wastes, can cause previously non-allergic people to develop an allergy. In addition to producing allergic reactions, dust mites can also cause nasal polyps growths within the nose see this article at 24 Medica. The constituents of house dust are show in the following figure:.

For those individuals, inhaling the house dust allergen triggers rhinitis allergica or bronchial asthma. People with allergies to house dust usually also have allergic reactions to house dust mite fecal material and cast skins.

Studies have shown that the most potent house dust allergens can be extracted from the feces produced by dust mites. Other important allergen-producing organisms that are found in house dust are found in Figure 1. The rest of this fact sheet, based on Chapter 10, "Mites," in Common-Sense Pest Control by Olkowski, Daar and Olkowski, will discuss biology of dust mites and will emphasize non-chemical control tactics. An allergist, a medical doctor specially trained to treat allergies, should be consulted for proper diagnosis and treatment of allergies.

One of the most strongly allergenic materials found indoors is house dust, often heavily contaminated with the fecal pellets and cast skins of House Dust Mites. Estimates are that dust mites may be a factor in 50 to 80 percent of asthmatics, as well as in countless cases of eczema, hay fever and other allergic ailments.

Common causes of allergy include house dust mites, cat dander, cockroach droppings and grass pollen. Symptoms are usually respiratory in nature sneezing, itching, watery eyes, wheezing, etc.

However, there are reports of a red rash around the neck. Other allergic reactions may include headaches, fatigue and depression. The wheeze-inducing proteins are digestive juices from the mite gut which are quite potent. An exposure to the mites in the first, crucial year of life can trigger a lifelong allergy. There is no cure, only prevention.

One must control house dust mite levels. The protein substances in the dust mite feces produces antibodies in humans who are allergic when these are inhaled or touch the skin. These antibodies cause the release of histamines which causes to nasal congestion, swelling and irritation of the upper respiratory passages.

A doctor can use skin tests and blood tests to confirm a suspected dust mite allergy. Diego Saporta, an otolaryngologist in Elizabeth, N. Do I often wake up with scratchy eyes? Do I sneeze repeatedly first thing in the morning? Saporta says.

Walking over a rug, sitting down in a chair, or shakings the bed clothes, makes the dried dust mite feces become airborne, making allergic person's symptoms worse. House dust mites, are too small to be visible to the naked eye; they are only to microns in length and have translucent bodies. It takes at least a 10X magnification to be able to correctly identify them.

The adult mite's cuticle covering has simple striations that can be seen from both the dorsal top view and from the ventral bottom view. The ventral view of the house dust mite reveals long setae hairs extending from the outer margins of the body and shorter setae on the rest of the body.

Through the microscope, one will see many oval-shaped mites scuttling around and over one another. There are eight hairy legs, no eyes, no antennae, a mouthpart group in front of the body resembles head and a tough, translucent shell, giving a "fearsome appearance.

Rugs and stuffed animals also make good homes for dust mites. While you can find dust mites all over the world, these creatures tend to favor hot and humid climates. Since they can burrow themselves deep into cloth fibers, they can also travel with you when you move or are on a vacation or business trip.

Dust mites themselves are allergenic, meaning they can cause allergies. They also leave behind skin and fecal matter that may also trigger allergies.

However, an allergic reaction to these pesky creatures may induce skin rashes. These are often red and itchy in nature.

If you have a dust mite allergy , you may experience symptoms year-round. You may also notice that your symptoms peak during the hot, humid summer months. Common signs of a dust mite allergy include:. Depending on the severity of your dust mite allergies, this condition may also trigger asthma.

You may notice wheezing, coughing, and chest pain as a result. The more you stay indoors, the more you may be prone to dust mite complications. The best way to treat allergies is to get rid of the underlying culprit.

Depending on the severity of your symptoms though, you may need immediate relief. Dust mites are difficult to get rid of completely, but removing as many as possible from your home can help prevent allergic reactions. The best way to get rid of dust mites is to target the areas they tend to live in and thrive. These include:. Frequent vacuuming, wet mopping, dusting, and washing can all treat dust mites. You just need to make sure you wash bedding in hot water and use wet cloths that can properly trap dust when you clean.

It goes in and comes right about out again. There is good news, especially for new parents: Portnoy and his expert colleagues think that dust mite allergies can be prevented, or at least significantly reduced, if parents do their best to prevent dust mite exposure, especially during the first six months of life.

And if you already are allergic to dust mites, allergy shots can significantly reduce symptoms for many years at a time. Portnoy acknowledges that minimizing exposure through dust mite covers, a good vacuum cleaner, bare floors and non-porous furniture might hurt the pocketbook at first — but he and his colleagues did a cost analysis and found that skipping those fixes means bigger bucks in the long run, because people end up buying more pricey antihistamines and asthma medications.
