When mites infest human skin, the resulting scabies may cause intense itching, a rash that resembles acne, blisters and scales, states WebMD. Scratching the skin may cause sores, and the itchiness is usually worse at night. It can take up to six weeks for the skin to react to mites.
Other possible symptoms of mites in humans include tiny bumps or blisters that form irregular, thin burrow tracks, notes Mayo Clinic. For adults, the tracks usually occur in the skin's folds, including in armpits, the inner elbow, on knees and on the buttocks. Other common areas include between fingers, around the male genitalia, the breasts and the inside of wrists. Some people may get a rash on the soles of their feet or on the shoulder blades. The most common areas for a rash on children are the palms of the hands and soles of the feet. Other common areas are the face, neck and scalp.
Some other skin conditions, such as eczema or dermatitis, may resemble scabies, states Mayo Clinic. If a person suspects that they may have scabies, it is important to see a doctor, as a prescription medication is required to get rid of scabies. Scabies is usually passed from one person to another through skin-to-skin contact, although it may be possible to get it from clothing, blankets or other objects, according to WebMD.
