Chiggers are tiny mites found in tall grass and weeds. If you brush against infested plants, chiggers might attach to your pant cuffs or shirt sleeves and make their way onto your skin. They fall off after a few days, leaving behind clusters of itchy, pink bumps. When scratched, chigger bites can become red and crusty.
Chigger bites usually heal on their own within one to two weeks. Vigorously scrub the area with soap and water to remove the mites. Control itching with calamine lotion or an over-the-counter anti-itch cream, such as hydrocortisone cream. Placing plastic wrap around the area treated with hydrocortisone cream might help soothe itching.
