Cattle oilers, also known as back rubbers or fly control oilers, are devices used in livestock management to control external parasites and provide relief from flies and other bothersome insects for cattle. The oil or insecticide mixture used in cattle oilers is designed to repel or kill common pests like flies, ticks, lice, and mites, which can cause irritation and spread diseases among the herd. The oiler's design facilitates the application of the solution onto the cattle's coats, reaching areas that are difficult to treat manually. Using cattle oilers as part of an integrated pest management strategy can contribute to the overall well-being of the herd by reducing the incidence of fly-borne diseases, minimizing discomfort, and improving the animals' overall health.
