    Malathion (Ovide) lotion, a prescription medication, kills live head lice and can kill some lice eggs (also called nits). After treating your child's hair and scalp with malathion, use a fine-toothed comb to remove the dead lice and their eggs from his hair. After you treat his scalp with malathion, use the comb to check his hair for lice every two or three days. If you find live lice seven to nine days after his malathion treatment, repeat the treatment.
