A tamper-proof bait station includes a container having a base and a lid that provides access to an interior that stores a poison bait that is consumed by pests. The base is securable to an external support member that supports the container above a ground surface. The support has an interior that is able to receive a weighted material to restrict movement of the container. A locking cap is provided that locks the lid to the base and is only removably upon applying axial or side pressure to the locking cap.
