Overview
Chigger bites are caused by the larvae of the chigger. The bite produces blisters (vesicles) and bleeding into the skin (purpura). These bites itch intensely and are usually located on exposed areas of the skin where the chigger larvae have access. This photograph demonstrates vesicle formation following the bites.
