WebCypermethrin is a synthetic pyrethroid used as an insecticide on a large scale. Cypermethrin is highly toxic to fish, bees, and aquatic insects, according to the National … WebCypermethrin is a synthetic pyrethroid primarily used as an insecticide. It acts as a fast-acting neurotoxin in insects. It is easily degraded on soil and plants but can be effective for weeks when applied to indoor inert surfaces. Exposure to sunlight, water and oxygen will accelerate its decomposition.
