Used primarily as an insect growth regulator, it prevents the normal development of insect larvae, effectively controlling pest populations without killing adult insects. It is commonly applied in agriculture, livestock, and pet care to manage fleas, flies, and other pests. Also found in household pest control products, especially for flea infestations in homes and yards. Its mode of action mimics juvenile insect hormone, disrupting metamorphosis and reproduction, making it effective at low concentrations and with low toxicity to mammals.
