Scabies mite, Sarcoptes scabiei, as seen under a microscope. The tiny mite bores and tunnels its way through living skin using its mouthparts. Mites make burrows and lay eggs causing violent itching, scabs and blisters. They feed on the liquid that oozes into their tunnels from surrounding damaged tissue. A single female can lay approximately 25 eggs every two or three days. Upon hatching the larvae begin making their own tunnels immediately. Infections can be spread by direct skin contact and is treated with insecticide lotions.
