Dust mites are also referred to HDM or house dust mites. These are
sightless, microscopic eight legged insects usually accounted for asthma
and most allergy symptoms such
as sneezing, watery eyes and itchiness. Despite the fact that these
arachnids do not bite, dust mites cause allergic reactions because of
their feces and bodily parts, even after their existence. Dust mites
possess protease - a potent digestive enzyme which triggers allergic symptoms.
