Tralomethrin is a pyrethroid insecticide.

Tralomethrin has potent insecticidal properties; it kills by modifying the gating kinetics of the sodium channels in neurons, increasing the length of time the channel remains open after a stimulus, thereby depolarizing the neuron for a longer period of time. This leads to uncontrolled spasming, paralysis, and eventual death. Insects with certain mutations in their sodium channel gene may be resistant to tralomethrin and other similar insecticides.
