Fluorapacin is primarily used as a rodenticide for controlling pest populations such as rats and mice in agricultural, urban, and industrial settings. It acts as a potent anticoagulant, disrupting the blood clotting process by inhibiting the enzyme vitamin K epoxide reductase, leading to internal bleeding and death in target species. Due to its high toxicity and delayed action, it is effective in single-feeding applications, reducing the likelihood of bait shyness. Fluorapacin is often formulated in bait stations or blocks to minimize exposure to non-target animals and humans. Its use is highly regulated and typically restricted to licensed pest control professionals to prevent environmental contamination and accidental poisoning.
