Addressing the Global Challenge of Pediculosis and Pesticide Resistance: A Review of Current and Emerging Lice Treatment Modalities, from Chemical Pediculicides and Essential Oils to Non-Chemical Approaches like Wet Combing and Heated Air Devices
Lice infestations (pediculosis) remain a prevalent global public health issue, frequently affecting school-aged children and necessitating effective, reliable treatment. The traditional use of chemical pediculicides, such as permethrin, is increasingly complicated by the development of pesticide resistance in lice populations, leading to treatment failures and the need for new solutions.
Effective treatment now often involves a multi-pronged approach, which may combine prescription or over-the-counter topical treatments with rigorous non-chemical methods. Wet combing with a fine-toothed nit comb is highly recommended to physically remove lice and nits, emphasizing the importance of a second treatment nine to ten days later to kill newly hatched nymphs.
