MouseX Ready Trays are a new approach to effectively kill unwanted rats and mice from industrial buildings, livestock premises, homes, barnyards and any area where the unwanted pests inhabit. MouseX Ready Trays are also safe for birds of prey with no risk of secondary kill. MouseX Ready Trays are premeasured bait trays that make baiting easy, just peel off the bait tray cover and set the tray out where you see rat or mouse activity.
