A variety of mites are known to bite humans and cause irritation, itchy papules and rashes. Most of these mites are actually parasites of other animals not humans, but will bite humans when their normal hosts are not present. These mites are mostly nest parasites of birds, rodents and other animals that blood-feed on their normal hosts and then return to the host’s nest. They do not remain on the animal or human that they feed on.
Mite bites cause red papules, and these bites can be extremely itchy. The free-living mites tend to bite in areas where clothing rubs. Scabies mites tend to occur most frequently on the hands and wrists, armpits and groin area.





Other mites known to cause contact dermatitis include a variety of grain mites in the genera Tyrophagus, Glyephagus and Acarus.
