Dichlorvos is used to control household, public health, and stored product insects. It is effective against mushroom flies, aphids, spider mites, caterpillars, thrips, and white flies in greenhouse, outdoor fruit, and vegetable crops. Therapeutically, dichlorvos is used to treat a variety of parasitic worm infections in dogs, livestock and humans. Dichlorvos can be fed to livestock to control botfly larvae in the manure. It acts against insects as both a contact and a stomach poison. Dichlorvos is available in aerosol and soluble concentrate formulations. It is used as a fumigant and has been used to make pet collars and pest strips.
Dichlorvos is one of a class of insecticides referred to as organophosphates. These chemicals act by interfering with the activities of cholinesterase, an enzyme that is essential for the proper working of the nervous systems of both humans and insects. Please refer to the Toxicology Information Brief on cholinesterase-inhibition for a more detailed description of this topic.
