Female mites typically lay between 10 and 25 eggs during their lifespan. These eggs take two to three days to hatch into larvae. The larvae move to the skin's surface and are fully grown within two and a half weeks. This is a never-ending cycle until the scabies infestation is eradicated from anyone infected by them.
Once a mite has made contact with human skin it generally burrows into the skin immediately. They are particularly drawn to burrowing into wrinkled and rough skin areas such as the knees, elbows and knuckles.
Scabies can live up to 36 hours without a human host.
