D. folliculorum has a rudimentary gut, and no anus. The entire life cycle of D. folliculorum takes 14–16 days. Adult mites copulate at the top of the hair follicle, near the skin surface. Eggs are deposited in the sebaceous gland inside the hair follicle. The heart-shaped egg is 0.1 mm (0.0039 in) long, and hatches into a six-legged larva.
