 Also known by their Latin name ‘ediculosis pubis’, crab lice are very tiny
insects that infest the pubic hair and survive by feeding on human blood. These
parasites are most often spread by sexual contact; in a few cases, they may be
picked up through contact with infested bedding or clothing.
Symptoms
The primary symptom of infestation is itching in the pubic area. Scratching may
spread the lice to other parts of the body; thus, every effort should be made to
avoid touching the infected area, although this may be difficult.
Diagnosis
Pubic lice are diagnosed easily because they are visible to the naked eye. They
are pinhead size, oval in shape, and grayish, but appear reddish-brown when full
of blood from their host. Nits, the tiny white eggs, also are visible and
usually are observed clinging to the base of pubic hair.
Treatments
Lotions and shampoos that will kill pubic lice are available both over the
counter and by prescription. Creams or lotions containing lindane, a powerful
pesticide, are most frequently prescribed for the treatment of pubic lice.
Pregnant women may be advised not to use this drug, and a physician’s
recommendations for use in infants and small children should be followed
carefully.
Itching may persist even after the lice have been eradicated. This is because
the skin has been irritated and requires time to heal. Soothing lotions are
essential lavender oil, or calamine which may offer temporary relief.
To aid in treatment, the complete shaving of the genital region makes life more
difficult for these critters as they typically rely on hair for support.
Prevention
All persons with whom an infested individual has come into close contact,
including family and close friends as well as sex partners, should be treated to
ensure that the lice have been eliminated. In addition, all clothing and bedding
should be dry-cleaned or washed in very hot water (125° F),dried at a high
setting, and ironed to rid them of any lice. Pubic lice die within 24 hours of
being separated from the body. Because the eggs may live up to six days, it is
important to apply the treatment for the full time recommended.
