Permethrin is an insecticide in the pyrethroid chemical family. Being a neurotoxic synthetic pyrethroid, it acts on the nervous system of insects. It interferes with sodium channels to disrupt the function of neurons and causes muscles to spasm, culminating in paralysis and death of arthropod. It affects sodium transport across the neuronal membranes in arthropods, thus causing depolarization. It is a mixture of a cis -trans isomer.
