The female scabies mite burrows or tunnels into the outer layer of skin in a thin red line about a half-inch long and then lays eggs. Such a burrow is usually very hard to identify. The first location is usually in the webs between the fingers or toes, around the wrist or the navel. It can also be found on the back of elbows, the folds of the armpits, the beltline and abdomen, about the creases of the groin, and on the genital organs. Small children, especially babies, may have involvement of the face, scalp, palms of the hands, or soles of the feet.

In persons without previous exposure, it may take four to six weeks for symptoms to develop. In persons with previous exposure to scabies, itching may develop in one to four days after infestation.
