The individual mites remain external to the epidermis within the follicle, but appear to be within the skin because they are below the general outer surface of the host. The mite Demodex canis is a common cause of demodicosis in dogs. Demodex mites are microscopic, cigar-shaped and have very short legs. These mites seem to feed on epidermal cells.
Hundreds of thousands of the tiny wind-soaring and itch-inducing critters can fall from trees every day and are packed with a venom that can paralyze prey 166,000 times their size.
A dust mite allergy might “take on the appearance of insect bites,” or a skin rash, says Dr. Faix. It also can manifest as asthma or allergy-like upper respiratory symptoms.
These mites remain external to the true outer layer of the skin (the epidermis) which also lines the tube of the hair follicle.
