Head lice are caused by the host-specific, ectoparasitic insect Pediculus humanus capitis De Geer and remain a common human infestation. As a response to increasing resistance of head lice to present insecticidal agents, additional agents must be pursued. Inasmuch as nicotine has been used for controlling poultry lice, an in vitro study assessing its possible usage for human head lice was performed. Nicotine proved not to be an efficient insecticide, although it may facilitate removal of adult lice because it induces muscle twitches that may affect the insect's normal grip on hair follicles.
头虱是由宿主特异性的体外寄生虫人虱头亚种引起的，仍然是一种常见的人类感染。由于头虱对现有杀虫剂的抗药性不断增加，必须寻找其他药物。鉴于尼古丁已被用于控制家禽虱子，因此进行了一项体外研究，评估其用于人类头虱的可能性。尽管尼古丁可能会促使成年虱子脱落，因为它会引起肌肉抽搐，可能影响虱子对毛囊的正常抓握，但它被证明不是一种有效的杀虫剂。
