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 rapid knockdown. It is also applied in public health programs for controlling nuisance insects such as mosquitoes and flies in residential and recreational areas. Carbaryl is used in formulations for lawn care and turf management to protect against grubs and other soil-dwelling pests. In addition, it finds use in veterinary applications for managing external parasites on livestock and pets, though with caution due to its toxicity. Its relatively short residual activity makes it suitable for integrated pest management (IPM) programs where repeated applications are timed to pest life cycles. Care must be taken during application to avoid exposure to bees and aquatic organisms, as carbaryl is highly toxic to beneficial insects and aquatic life.
