Dust mites are tiny spiderlike creatures (arachnids) that feed
mostly on flakes of dead human skin. Mites do not bite humans or spread
Dust mites may cause allergies and asthma symptoms in some people.
When allergies are present, they are triggered by material in the stool of dust
mites rather than by the insects themselves.
Dust mites are usually found where conditions indoors are warm and
damp (high humidity). Dust mites are found mostly in carpeting, bedding,
pillows, mattresses and box springs, furniture, and stuffed animals. Having
dust mites in the home is not caused by poor house cleaning.
The number of dust mites tends to decrease during the winter months
and at high altitudes.
