Registered depot ectoparasiticides are freely available over-the-counter antiparasitic drugs used to treat ectoparasitic infestations, where parasitic organisms live primarily on the surface of the host. All products are used exactly as directed in terms of their classification under Act 36 of 1947 (Fertilizers, Farm Feeds, Agricultural Remedies and Stock Remedies Act). The products are registered to treat ectoparasites in cattle, horses and sheep, so the only extra-label use is that it is being used on rhino instead. This treatment benefits the rhino owner, does not harm the environment, does not harm other living organisms, has no adverse effects on tourism or the economy, is cost-effective, legal and can be completed in under an hour. In other words, it is a minimally-invasive procedure intended to uphold the status quo with regard to the trade in animal parts for as long as is necessary.
