Cypermethrin Uses
Cypermethrin is used in the treatment of Parasitic Infestations.
How Cypermethrin works
Cypermethrin is a synthetic pyrethroid that acts on the nervous system of external parasites such as ticks, fleas, lice, and mites. It works by disrupting the normal function of sodium channels in the parasite’s nerve cells, leading to continuous nerve stimulation. This causes paralysis and eventual death of the parasites, thereby helping to eliminate them from the dog’s skin and coat.
