Treat Lice (Pediculosis)

Infestation of human parasitic lice, which feed exclusively on human blood and lay eggs (nits) on body hairs or clothing fibers; after nits hatch, lice must feed within 24 hours or die. Lice crawl and attach superficially to the epidermis and hair. One female louse deposits approximately 60 to 150 nits to hair shafts. Nits survive by ingesting blood from the human host. A louse bite injects a toxin into the skin. Mild irritation and a purpuric spot results. Repeated bites cause sensitization to the toxin, leading to more serious inflammation. In severe cases, sensitization causes wheals or a rash on the trunk. Scratching result in secondary bacterial infection.

Pediculosis capitis (Head Lice): confined to scalp and, occasionally, eyebrows, eyelashes, and beard.
Pediculosis corporis (Body Lice): found next to skin in clothing seams; move to the host only to feed on blood.
Pediculosis pubis (Crab Lice): found primarily in pubic hairs; may extend to eyebrows, eyelashes, and axillary or body hair.
