Dust mite is a major source of allergies. Not only the body itself but its larval, debris, fecal matter and egg do also cause allergy symptoms to human. A typical dust mite can produce an amount of fecal matter which is almost 200 times of its weight, during its life. These fecal particles are in fact harmful allergens which will cause people allergy symptoms like asthma, itchiness, sneezing, inflamed/infected eczema, watering eyes, runny nose, (if asthma), lungs clogging up, etc.
The average life cycle for a male house dust mite is 2 to 3 months, while a mated female house dust mite can live for about 70 days, laying more than 100 eggs in her life.

Fecal matter of dust mite at our home
Dust mites do not bite yet their fecal particles and debris is the major source of allergens. The fecal particles are so tiny that they can suspend in air for up to 20 minutes and be easily inhaled by human.
The fecal matter is water-soluble and can dissolve into any moist surface. As the surface of our respiratory tract (including the lungs) is wet, it is easy for the allergens to deposit on it. Even worse, once these fecal particles have dissolved, some enzymes will be released, which will attack the mucus and structure of our respiratory system and eventually cause allergy symptoms.

Allergy symptoms triggered by dust mite
In accordance with recent research, about 90% of Asthma; 70% of Atopic Dermatitis cases in human are caused by allergens produced by dust mites. Yet few people would notice that even conjunctivitis inflammation, otitis media (Inflammation of the middle ear) or dermatitis are probably caused by allergens from dust mites.
If your children are suffering from prolonged clogging, running nose, influenza or other allergies, it is advised that an allergen test performed by physicians may help identify the cause of the allergy symptoms and take required actions.
