Nicotine spray is considered a natural insecticide because it is derived from a plant (others include pyrethrum and neem, for example). Nicotine is found in the nightshade family of plants (solanaceae), predominantly in tobacco, and in lower quantities in tomato, potato, eggplant and pepper. Nicotine-based sprays appear to be in the process of being banned as insecticides in the U.S. (if only it could be banned as a cancer-and-disease-causing stick as well) because of its potential link to bee susceptibility to disease, which has now made me think twice about using it again.
