Parasite-Chiggers
I often see chiggers as an external parasite that is really, really itchy. The term chigger is a common name for the six-legged larva of any of several blood-sucking mites. Chiggers normally feed on the blood of animal hosts such as birds, reptiles, and small mammals, but they also bite humans. People who go hiking, camping, or simply playing in the backyard or park can pick up a case of chiggers. Chiggers cause tiny red itchy bumps on the skin. These bites can be differentiated from flea bites because flea bites usually make a tight grouping of 3-5 bites.
