Empenthrin (also called vaporthrin) is a synthetic pyrethroid used in insecticides. It is active against broad spectrum of flying insects including moths and other pests damaging textile. It has low acute mammalian toxicity (its oral LD₅₀ is above 5000 mg/kg in male rats, above 3500 mg/kg in female rats and greater than 3500 mg/kg in mice). It is however very toxic to fish and other aquatic organisms (96-hour LC₅₀ in Oncorhynchus mykiss is 1.7 μg/L, 48-hour EC₅₀ in Daphnia magna is 20 μg/L).
