Are dust mites harmful?
House dust mites do not bite or sting. The mite generally lives on shed human skin cells, which are pre-digested by the fungus Aspergillus repens. An average person sheds about 1.5 grams of skin a day (approximately 0.3-0.45 kg per year), which is enough to feed roughly a million dust mites. Further, dust mites in bedding derive moisture from human breathing, perspiration, and saliva.
