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.
Tetramethrin has an expected half-life of 12.5-14 days in soil and 13-25 days in water.
