Chemical compound
Tetramethrin is a potent synthetic insecticide in the pyrethroid family. It is a white crystalline solid with a melting point of 65–80 °C. The commercial product is a mixture of stereoisomers.
It is commonly used as an insecticide, and affects the insect's nervous system. It is found in many household insecticide products.[1]
Tetramethrin has an expected half-life of 12.5–14 days in soil and 13–25 days in water.[2] Tetramethrin was classified as a Category 2 carcinogen in 2018 by Directorate-General for the Environment of the European Commission.[3]
