Definition of Dust mite
Dust mite: A tiny microscopic organism that is the primary cause of allergies related to house dust. The term "dust mite allergy" is a misnomer because it is the fecal excretion of these mites to which people are allergic. Dust mites can therefore trigger allergic reactions even when dead.Source: MedTerms™ Medical Dictionary
