Abstract
Abstract This invention relates to the safe containment of a rodenticide prior to their placement in tamper-resistant bait stations and more specifically to their containment in a device that will afford maximum protection of the baits from unauthorized contact with humans, non target species and the environment. A tray carries a rodenticide bait block and is packaged and dispensed in an outer case, or covered with a cover member, which is removed before the tray and bait is placed in a bait station feeder.
