According to UC Davis, humans are sometimes bitten by mites. Mites usually feed from other animals, but, if they are not available, mites go after humans. Although some mites just bite and leave, scabies sometimes live under people's skin.
UC Davis explains that, on humans, mite bites show up as itchy red bumps or rashes. Bites from scabies tend to appear in the areas where skin is thin, such as the hands, wrists, armpits and groin. Other types of mites are more likely to bite where clothing rubs against skin.
In addition to scabies, the Illinois Department of Health identifies several types of mites that occasionally bite humans. These include varieties of itch mites, rodent mites, bird mites and chiggers.
