Propoxur is widely used as a carbamate insecticide in both household and agricultural settings. It is effective against a variety of pests including cockroaches, ants, fleas, ticks, and mosquitoes. Due to its fast-acting nature, it is commonly found in indoor pest control products such as sprays, baits, and foggers. It is also used in veterinary applications to control parasites on pets and livestock. In agriculture, Propoxur helps manage insect pests on crops, particularly on fruits and vegetables. Its use is limited in some areas due to toxicity concerns to non-target species, including humans and aquatic life.
