- Human demodex has no intermediate host. It passes its whole life in the hair follicle
and sebaceous glands of man. It is bisexual and reproduces through intercourse at the openings of hair
follicles, after which it goes back to surrounding hair follicles and sebaceous glands to lay eggs and
The life cycle of human demodex can be divided into five stagers [sic]. It is estimated that about 12 hours after mating, the demodex will lay its eggs which will hatch 60 hours later. After 36 hours of feeding, the demodex larva will moult into undeveloped protonymphs which move with sebum. After another 72 hours, they will moult again into nymphs which are stronger. They are now capable of climbing out of hair follicles and sebaceous glands to the surface of the skin. Another 60 hours later, they finally moult into adult demodex... It avoids light, and loves warmth. Therefore, it is more active when its human host is sleeping. Most adult demodex crawl out of the hair follicle at this time to find mates to copulate at the openings...
Its secretion, excretion and dead bodies will accumulate in the hair follicles and sebaceous glands. Its parasitic activities will cause physio-chemical stimulation and local adverse reaction... Attention and further study are needed...
