Dichlorvos, also known as DDVP, is an organophosphate insecticide and acaricide used in agriculture and in the home to control a wide range of pests. It is a colorless to yellow-brown liquid with a characteristic, pungent odor. Dichlorvos is toxic to humans and can cause a variety of health effects including nausea, headaches, and skin and eye irritation. It is also toxic to fish and other aquatic life, and it can accumulate in animal tissues. Dichlorvos is highly soluble in water and is easily absorbed through the skin. It is readily broken down by sunlight and is not persistent in the environment.
