The best thing to do with a chigger bite is to reduce itching with an anti-itch medication, according to Healthline. Reducing itching helps deter scratching, which can negatively affect proper healing of the bites.
Hydrocortisone and calamine lotion are good over-the-counter anti-itch medication options, reports Healthline. Applying ice to the bites is another approach to mitigate itching. It is also important to avoid irritants, such as a hot bath or shower, that can escalate itching. The healing time for chigger bites is anywhere from one to three weeks. If a person develops an infection or experiences more severe symptoms from bites, a trip to the doctor is in order.
