Itching usually occurs several hours after the chiggers attach to the skin. The bite is painless.
Signs and tests
A doctor can diagnose chiggers by examining the rash.
The goal of treatment is to stop the itching. Antihistamines and corticosteroid creams or lotions may be helpful.
Calling your health care provider
Call for an appointment with your health care provider if the rash itches very badly, or if symptoms get worse or do not improve with treatment.
Avoid outdoor areas contaminated with chiggers, if known. Applying bug spray containing DEET to skin and clothing can help prevent chigger bites.
