Description
Technical coumaphos is a tan crystalline solid with a slight sulphur odour. It is insoluble in
water; slightly soluble in acetone, chloroform, and ethanol; and soluble in organic solvents.
Coumaphos when heated undergoes decomposition and releases very toxic fumes of sulphur
oxides, phosphorous oxides, and chlorides. It is used for the control of a wide variety of
livestock insects, including cattle grubs, screwworms, lice, scabies, flies, and ticks. It is used
against ectoparasites, which are insects that live on the outside of host animals such as sheep, goats, horses, pigs, and poultry. Coumaphos is incompatible with alkalis, strong oxidising
agents, pyrethroids, and piperonyl butoxide. The U.S. EPA has grouped coumaphos as RUP.

Uses
Coumaphos is used to control larvae of Diptera and ticks on cattle.
It has also recently been used to control Varroa mite in honeybees.
