Each year in the U.S., there are an estimated 6 to 12 million head lice infestations among children aged 3 to 11 [1.3.4]. Understanding **what is toxic to lice** is key to effective treatment, involving various chemical agents called pediculicides that target the parasite's life cycle [1.5.3].

Infestations of lice, or pediculosis, affect millions of people, particularly school-aged children, every year. Understanding what is pediculicide, and how to use these medications effectively, is the first step towards successful treatment and prevention.

While historical studies reported high efficacy, recent clinical data suggests that the success rate of permethrin is no longer universally high due to factors like emerging resistance and application errors. Once considered a near-curative treatment for many parasitic infestations, permethrin's effectiveness now varies depending on the specific condition, location, and proper usage.

Head lice infestation, or pediculosis capitis, is a widespread public health issue, with millions of cases reported annually worldwide. This high prevalence often leads to the question: **Is there a pill for head lice?**
