Cynoff EC Insecticide Beetles such as in the gapsHow Cynoff EC Insecticide Works Cynoff EC Insecticide contains 24 percent cypermethrin, a higher dosage than similar insecticides on the market. It's a synthetic pyrethroid, which mimics the same effects of naturally occurring pyrethrums in the wild. In nature, chrysanthemum flowers produce this substance to repel plant eating insects. In the lab, this synthetic chemical works on contact and paralyzes the insects, killing them after a short time.
