House dust mite
The house dust mite is a cosmopolitan guest in human habitation. Mites belong to the order same as spiders, and have existed for longer than insects. Dust mites flourish in the controlled environment provided to them by buildings. In nature they are killed by predators and by exposure to direct sun rays. Dust mites are considered to be the most common cause of asthma and allergic symptoms worldwide. The enzymes they produce can be smelled most strongly in full vacuum cleaner bags. It is just possible to see a dust mite under a magnifying glass, when the subject is well lit and placed on a black background. Bleach and strong soaps do not kill dust mites. A simple washing will remove most, in the waste water. Temperatures of over 60 degrees Celsius (140 degrees Fahrenheit) for a period of one hour are usually fatal to dust mites; freezing may also be fatal. Dust mites reproduce quickly enough that their effect on human health can be significant.
