Mites. Scabies is a mite that burrows into your skin, lays eggs, then burrows back out, leaving the tell-tale hole and red line mark. It is also known as the worst itch known to medical science. They are gotten rid of by a cream applied topically to your skin from your neck to your feet overnight, then washed off in the morning.
