A pest bait station comprising a container 100 having an entry point 102 and a poison/trap location 104. A ladder arrangement 106 provides access to the entry point. A climbing formation 108A is included in the ladder arrangement which is spaced from an end thereof remote from the entry point by a minimum design distance calculated to allow a target pest to ascend to the entry point , whilst preventing non-target animals from ascending. Alternatively the adjacent pairs of climbing formations of the ladder are spaced apart by a minimum distance. Further still the pest bait station may be fitted above the floor or ground surface so that a first climbing formation is spaced apart from the floor by a minimum distance of over 170mm to 175mm.
