Type II pyrethroids which contain an alpha-cyano group (e.g., deltamethrin, cyphenothrin, and fenvalerate) exert effects on sodium channels qualitatively similar to those of type I pyrethroids.

The effects of 4 different pyrethroid insecticides on sodium channel gating in internally perfused, cultured mouse neuroblastoma cells (N1E-115) were studied using the suction pipette, voltage clamp technique.
The rate of decay of the slow tail current strongly depended on pyrethroid structure and increased in the order deltamethrin, cyphenothrin, fenfluthrin and phenothrin.

Type II pyrethroids as represented by cyphenothrin, deltamethrin and fenvalerate which contain a cyano group at the alpha-carbon cause nerve membrane depolarization and block leading to paralysis of the animal.
Thus, it is concluded that the site of action of pyrethroids is the sodium channel, and that pyrethroids interact with the channel macromolecules that control the gating mechanism.
