Dust mites primarily feed on organic detritus such as dead skin of humans and dander. Since they survive on dead skin, the most ideal areas where they can feed include the bed sheets, blankets, towels, beds and mattresses. In reality, a normal individual sheds about 1.5 grams of dead skin flakes on a daily basis. These mites with the assistance of their pair of jaws are capable of breaking down their food. The saliva that is secreted by dust mites will grind the food. Similar to animals, the food will move down to the gut with the aid of wave like motions or peristalsis until it has been digested. Then digested food will move towards the anus to be defecated in the form of a pellet. It is not the bite that triggers an immune response from the human body. It is actually the presence of a particular protein in the feces. Dust mites do not really bite, what affects people is the certain allergen present in their feces.
What are the Symptoms observed when dust mite allergens are present?
The bite symptoms of dust mites are similar to the bites made by mosquitoes or other insects. Once the allergens released by the dust mites come in contact with the body, the immune system regard it as dangerous intruders such as viruses and bacteria. Consequently, it releases antibodies in an effort to neutralize the threat. Aside from causing irritation and itchiness to the skin, bites of dust mites or dust mites can cause some other allergic reactions. These are watery and swollen eyes, asthma, itchiness in the nose and throat, cough, redness of the eyes, frequent sneezing, runny nose and more. If exposure to dust mites is prolonged, this can result to atopic dermatitis, asthma and eczema. But, you need to know that not all of us can be allergic to dust mites. Other people do not show any kind of symptom once in contact with dust mite.
How to Prevent an Allergic Reaction to Dust Mite?
You need to find a way to detect the area that is contaminated with dust mites if you wish to know how to get rid of dust mites. The first step towards the control and prevention of bite reactions to dust mite is to detect the presence of dust mites. There are some companies that claim to have detection kits for dust mite. These devices can inform people whether there is a mild or severe case of dust mites in your home. But, there is no assurance regarding the effectiveness of these kits since there are no available reviews for them yet. A more arduous way of examining them will be to collect a sample of dust in water and then check it under a 10x microscope. Since both methods can be pretty painstaking, the only possible way to control the population of dust mites will be to keep the house clean, dry and cool.
In order to avoid allergies from dust mite, there are several simple precautions anyone can use. First and foremost, you need to wash the blankets, bed covers, drapes and pillow covers at least once a month using hot water. But you might have to do this more often once your house has become infested with dust mites. Another useful way to prevent dust mite bites is to replace feather filled pillows with synthetic materials. Dust mites grow dynamically in moist and humid conditions. These environmental conditions can be controlled using dehumidifiers and air conditioners. It is also helpful to make use of HEPA filters to clear the air of allergens in case dust mites are made airborne. This device filters with high efficiency particulate air. Yet, total dependence on this filter is not recommended since it will only clear the air and is not able to remove the dust mites which are burrowed in bed mattresses or in linens.
