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.[1] 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).[2] 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).[1]
