Chiggers live in tall grasses and brush, often in moist areas, and attach themselves to soft places on the skin using special mouth parts (chelicerae) to bite you and inject powerful enzymes that dissolve skin cells, providing food for the critter. They cannot burrow into the skin, but the enzymes irritate your body, and it walls off the damaged area. This wall (stylostome) itches and causes a red welt. Then time is the only cure as your body gradually neutralizes and absorbs the irritants.
