Doctor's Notes on How to Treat Chigger Bites
Signs and symptoms of chiggers are the presence of chiggers on the skin and intense itching, with flat or raise red bumps on the skin that may blister. Chiggers are barely visible to the naked eye; may have six legs while the adult forms have eight legs. Chiggers are a reddish color; juvenile forms that do the biting require a humid environment (for example, groin areas, armpits and skinfolds behind the knees).
Chiggers insert their feeding structures into the skin and these structures and associated chemicals cause the chigger bite skin symptoms and signs.
