The Protecta EVO Express is a state of the art rodent bait station, with the added benefit of a built in concealed paver for weight. The EVO is designed to allow easy entrance, above any accumulated snow, plus easily adapts to a snap trap station only using the Bells T-Rex rat trap. New side opening key makes for easier access in all weather. The EVO can either hold two T-Rex rat traps or up to 8 bait blocks or both, depending on your needs.
