Widely used as a larvicide to control mosquito populations, particularly in areas where vector-borne diseases like dengue, Zika, and chikungunya are prevalent. It is applied to standing water and other breeding sites where mosquito larvae develop, effectively disrupting their growth by inhibiting the nervous system. Due to its low volatility and persistence in water, it provides extended control in both urban and rural environments. Commonly used in public health programs for large-scale mosquito management. Safe for use in drinking water at recommended concentrations, making it suitable for treatment of water storage containers in endemic regions.
