Chiggers bit on the lips of my vagina?

Chigger bites don't carry diseases but can be very uncomfortable. Harvest mite larvae feed not by going under skin but by thrusting their small hooked fangs into the skin surface. The larvae do not burrow into the skin or suck blood. They inject fluid containing digestive enzymes into the skin that break down skin cells. The resulting liquefied skin tissues are then sucked back into the digestive system of the larva.
