Coumaphos is a nonvolatile, fat-soluble phosphorothioate with ectoparasiticide properties: it kills insects and mites. It is well known by a variety of brand names as a dip or wash, used on farm and domestic animals to control ticks, mites, flies and fleas.
It is also used to control Varroa mites in honey bee colonies, though in many areas it is falling out of favor as the mites develop resistance and as the residual toxicity effects are becoming better understood.
In Australia, its registration as suited to home veterinary use was cancelled by the Australian Pesticides and Veterinary Medicines Authority in June 2004 after the manufacturer failed to show it was safe for use on pets.
The compound has been linked to neurological problems in bees, and may be a factor in colony collapse.
