A bait station for rodents, an elongate, hollow tubular structure having a single opening to and from its interior. This station is formed of tubing fabricated, preferably, of tough, corrosion, weather and distortion resistant plastic such as a polyvinylchloride. Its preferred configuration provides that one end portion of its tubular structure is enlarged as to its cross sectional area to define a bait chamber the entrance to and exit from which is limited to a single passage, defined by its remaining length the remote end of which provides the single opening to and exit from the passage. The cross sectional area of said passage is made substantially less than that of said chamber. This precludes entrance by animals larger than that of the target rodents. Preferred bait embodies a non-poisonous anti-coagulant, ingestion of which produces a breakdown of the rodent's life support system and its expiration, but not until some time after the rodent leaves the vicinity of the bait station. Most preferred embodiments of the invention have one or more very small apertures in the wall of their bait chamber and the end remote therefrom arranged for press fit in a tubular adapter which forms an extension thereof. This adapter may be inserted in a hole formed in the wall of a dumpster, other waste container or building, adjacent its base, and suitably secured thereto to dispose the interconnected bait station within the structure to which it applies with only its access opening revealed at the exterior of the wall.
A bait station for rodents including one section defining an enclosed bait chamber and a relatively projected entrance-exit section defining a passage into and out of said chamber, said entrance-exit section having an inner end connected to said one section and opening into said chamber and an outer end which is normally open to define the access opening to said chamber which is limited as to its cross section to exclude the passage therethrough of any object perceptibly exceeding in size the target rodents, aid one section defining one end portion of said station, said access opening being at the opposite end of said station which is most remote from said chamber, said one section being defined by plastic tubing closed by cap means at least a portion of which is releasably secured thereto and said plastic tubing having a single access opening connected at the outer surface thereof to one end of a tube element which is anchored thereto and extends therefrom to define said entrance-exit section.
A bait station for rodents including one section defining an enclosed bait chamber and a relatively projected entrance-exit section defining a passage into and out of said chamber, said entrance-exit section having an inner end connected to said one section and opening into said chamber and an outer end which is normally open to define the access opening to said chamber which is limited as to its cross section to exclude the passage therethrough of any object perceptibly exceeding in size the target rodents, said outer end of said entrance-exit section including external means for coupling thereof to a wall structure to align said access opening and place it in direct communication with an opening in and in a position to open from an exterior surface of said wall structure.
A bait station for rodents including one section defining an enclosed bait chamber and a relatively projected entrance-exit section defining a passage into and out of said chamber, said entrance-exit section having an inner end connected to said one section and opening into said chamber and an outer end which is normally open to define the access opening to said chamber which is limited as to its cross section to exclude the passage therethrough of any object perceptibly exceeding in size the target rodents, and a waste container or receptacle, said entrance-exit section being coupled to a wall portion of said container or receptacle to have the end thereof remote from said chamber open from the exterior surface of said receptacle or container adjacent the base thereof.
A bait station for rodents comprising a first tubular element defining a bait chamber, said first tubular element being short in length, capped at each of its opposite ends and having an opening thereto between said ends, said opening being rimmed by an adapter to which one end of a second substantially longer tubular element is telescopically secured to define an entrance-exit passage in connection with said chamber having an entrance end which is normally open to provide the opening to said chamber for rodents, said rodent opening being limited as to its cross section to exclude the passage therethrough of any object perceptibly exceeding in size the target rodent and at least a portion of said capped ends of said first tubular element being releasably secured for access to said bait chamber for the cleaning thereof or introduction therein of bait, as needs require.
