Abstract: A bait station providing a holder for dispensing liquid bait in a refillable manner. The liquid bait is kept in a reservoir at the bottom of the bait station base. Fit into an open end of the base is an interior section comprised of two domes. The interior section fits into the base above the bait reservoir. A lid is secured over the end of the base. The dimensions of the domes are selected such that the domes contain the liquid bait if inverted and one dome contains the liquid bait held in half the reservoir. The access ports at the top of the base and between the domes provide access to the liquid bait. Refilling the station with liquid poison is effected either through a port in the lid of the bait station or by removal of the lid. Target insects enter the bait station through one or more access ports and then travel through an interior passageway to the liquid bait, which can be both an attractant and a poison.

Abstract: A liquid bait station for ants has separate nested inner and outer container sections with the inner container forming a liquid bait reservoir. The inner container section or reservoir has a lid that is closed whenever the outer container is closed, and access to the reservoir of liquid bait by the ants is indirect via one or more container access ports leading to a compartment inside the outer container and then via separate reservoir access ports leading from the compartment to the reservoir. In one embodiment, the reservoir lid comprises a raised portion in the inner surface of the outer container's own cover and the reservoir access ports are formed by depressions in that raised portion. In a second embodiment, the inner and outer container sections have separate lids, but at least one tang depending from the outer cover closes and holds down the inner lid whenever the outer cover is closed. The reservoir access ports can be holes in the inner lid.
