Sarcoptes mites have a '''3 week''' life cycle. The female lays eggs in the epidermis in an '''egg laying pocket'''. The female feeds on liquid oozing from damaged tissue. The eggs then hatch in 1 week and '''6 legged''' larvae are released. They crawl to skin surface and then burrow back into the epidermis into '''moulting pockets'''.
