Do not resort to desperate measures in an attempt to kill head lice. Do not apply kerosene, gasoline, isopropyl alcohol, or lighter fluid to the hair; do not use veterinarian products, agricultural or lawn-care chemicals, and any other insecticide that is not labelled for head lice. Each year, such home remedies kill or maim some children. In misusing such products, safety is ignored. As an example, kerosene is not only extremely flammable, but it is absorbed through the skin and can be toxic, even causing death. Human safety always should be the main concern.
