Rotenone Insecticide

Q: I have been unsuccessful in finding rotenone, an organic insecticide I have used for many years. Where can I get some?

A: Rotenone has been used as an insecticide for more than a hundred years and as a fish poison for more than a thousand years. It is derived from the roots of tropical plants. These days, in order to balance the threat to fish in nearby streams with the need for organic insecticides, rotenone is usually mixed with pyrethrin, another organic insecticide. You should be able to find it locally and online from companies that specialize in organic gardening.
