Which is a non-chemical method to treat lice?

• A. 0.5% Malathion Lotion
• B. 0.9% Spinosad Suspension
• C. Fine Combs
• D. 5% Benzyl Alcohol

Answer: (C)

Non-chemical lice treatment uses physical removal rather than pesticides. A fine comb is designed to mechanically lift and remove lice and their eggs from the hair shaft. This method relies on thorough combing, often over several sessions, to reduce the lice population and clean out nits without introducing any chemical agents. It’s useful when chemical treatments are unsuitable, or when combined with other methods to improve overall effectiveness. In contrast, the other options involve chemical pediculicides that kill lice through chemical action. Malathion lotion, spinosad suspension, and benzyl alcohol work by affecting the nervous system or suffocating the insects, rather than simply removing them physically.
