Dust mites are to be expected in every home and apartment, and they can become impressively abundant on and around beds. It shouldn’t be a surprise if one or a few wander from a pillow case into the dark and moist crevice that is an ear canal. Is this a case of otoacariasis (infestation by mites), and would the mites perpetuate there? Hardly. We wonder what the mites were whispering while there.
