Comprehensive Evaluation of Mosquito Repellent Products: Efficacy, Safety, and Public Health Implications

Mosquito-borne diseases such as dengue, chikungunya, and malaria remain major public health challenges in South Asia, particularly in Bangladesh, where mosquito repellents are widely used as primary preventive tools. This study presents a comparative evaluation of commonly used repellent products, including mosquito coils, liquid vaporizers and aerosols, DEET-based creams, and natural formulations, focusing on their efficacy, protection duration, and potential health risks. Efficacy was assessed using controlled laboratory methods, including chamber-based exposure and arm-in-cage tests against Aedes aegypti (Barnard & Xue, n.d.). Safety was evaluated through in vivo toxicological analysis in
