Chiggers are small, bright red mites that thrive in grassy areas and bite humans and animals, causing extreme itching and discomfort. Other synonyms for chiggers include harvest mites, redbugs, and trombiculid mites. These tiny creatures are often found in humid, wooded areas and can be difficult to detect with the naked eye. Other regional synonyms for chiggers include berry bugs, scrub itch mites, and jiggers. While chigger bites are generally harmless and do not transmit disease, they can be extremely irritating and uncomfortable. Preventative measures, such as wearing long pants and sleeves and using insect repellent, can help to avoid chigger bites.
