Quick Summary

Neotrombicula autumnalis, commonly known as the European chigger, is a type of mite larva that can be a pest to humans and animals. These tiny arachnids, often called harvest mites, are parasitic only in their larval stage. They attach to the skin and inject digestive fluid, causing intense itching and dermatitis. After feeding, the larva drops off to develop into a non-parasitic nymph and adult, which feed on plant material or other arthropods. Unlike some other chigger species, Neotrombicula autumnalis can affect livestock like cattle, dogs, and horses, in addition to humans.1
