Carbaryl is widely used as a broad-spectrum insecticide in agriculture, forestry, and home gardens. It effectively controls a variety of insect pests including aphids, mites, thrips, and caterpillars on fruits, vegetables, and field crops. Due to its relatively short residual activity, it is suitable for integrated pest management programs where quick degradation is desired. It is also used in public health programs to control mosquito larvae and other nuisance insects. Carbaryl is available in formulations such as wettable powders, granules, and sprays, making it adaptable for different application methods. However, it is highly toxic to beneficial insects like bees and should be used with caution during flowering periods.
