Carbaryl solution is widely used as a broad-spectrum insecticide in agriculture, horticulture, and home gardening. It effectively controls a variety of insect pests including aphids, mites, thrips, and caterpillars on fruits, vegetables, and ornamental plants. Due to its systemic and contact action, it quickly disrupts the nervous system of insects, leading to paralysis and death. It is also applied in public health programs to manage mosquito populations and other nuisance insects, helping reduce the spread of insect-borne diseases. In addition, carbaryl is used in pet shampoos and sprays to control fleas and ticks. Care must be taken during application as it is toxic to beneficial insects like bees and can affect aquatic life. It is typically applied through spraying and should be used according to label instructions to minimize environmental impact and avoid residue on food crops.
