Insecticides

Pyrethrins are insecticides that are derived from the extract of chrysanthemum flowers called pyrethrum. Pyrethrins are widely used for control of various insect pests.   

Bifenthrin is an insecticide in the pyrethroid family. Pyrethroids are manmade versions of pyrethrins, which come from chrysanthemum flowers. Products containing bifenthrin come in many forms, including sprays, granules, and aerosols. There are more than 600 products containing bifenthrin available in the United States.

Larvicides

Larvicides are products used to kill immature mosquitoes before they become adults. They can be either biological (such as toxin from specific bacteria that is lethal to mosquito larvae but not to other organisms) or chemical products, such as insect growth regulators, surface films, or organophosphates. Larvicides are applied directly to water sources that hold mosquito eggs, larvae or pupae. When used well, larvicides can help to reduce the overall mosquito burden by limiting the number of new mosquitoes that are produced. Larvicides are regulated by the US Environmental Protection Agency.
