Previous Next 1 of 9

Chiggers are tiny mites found in tall grass and weeds. If you brush against infested plants, chiggers may attach to your skin. They fall off after a few days, leaving behind red, itchy welts.

Chigger bites usually heal on their own within one to two weeks. In the meantime, control itching with an over-the-counter anti-itch cream, such as hydrocortisone cream. Consult your doctor if your skin appears infected or if the bites seem to be spreading to other parts of your body.
