What are “larvicides”? How are they used? A.
Larvicides, regulated by the US Environmental Protection Agency (EPA), are products used to kill immature mosquitoes (larvae). They can be either biological (such as toxin from a 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, and are applied directly to water sources that hold mosquito eggs or larvae. When used properly, larvicides can help to reduce the overall mosquito population by limiting the number of new mosquitoes that are produced.
