  • Nits on the Hair

    One female louse deposits approximately 60 to 150 nits to hair shafts or crawls onto the body to feed (corporis). Nits survive by ingesting blood from the human host. A louse bite injects a toxin into the skin. [quizlet.com]

    These lice feed on human blood and lay their eggs (nits) in body hairs or clothing fibers. After the nits hatch, the lice must feed within 24 hours or die; they mature in 2 to 3 weeks. [basicmedicalkey.com]

    The body louse lays nits on clothing, especially the inner seams of fabric; therefore eggs are not found on the hair as with other lice. CA0611Pediculosis_Exam Diagnosis depends on observation on observation of nits, nymphs or the adult louse. [clinicaladvisor.com]
