This invention generally relates to pest control products, and more particularly to reusable bait stations used for pest control applications.
Bait stations are used in a variety of environments for pest control. As their name implies, they contain bait which attracts a target animal (also referred to as a pest), or a class of target animals. The bait contains powerful active ingredients used to kill the pest that ingests the bait. In the case of rodents, for example, the bait is a rodenticide. The bait station can be generally described as a housing that encloses an interior space which contains the bait. The housing has one or more entry points that allow the pest to enter the device and ingest the bait. Once ingested, the pest typically leaves the bait station and dies some time thereafter.
The housings typically include provisions for holding the bait in place. For example, preformed blocks of rodenticide or soft bait rodenticide, etc. may be situated on rods or the like within the interior space of the housing. This keeps the bait readily accessible to the pest. Such bait stations may come in a variety of sizes, have a variety of cosmetic designs, and allow for the use of multiple pieces of bait at once.
While such bait stations have proven to be an effective means for pest control, they are not without some drawbacks. For example, as mentioned above the bait contains powerful active ingredients which may be harmful to other animals. As also mentioned above, the pests do not typically die within the bait station after ingesting the bait. Rather, the pests typically leave the bait station and die elsewhere. The bait itself tends to crumble and flake when gnawed on or eaten by the pest. Some of these crumbles or flakes may become temporarily caught in the pest's fur. Further, the same crumbles or flakes may also fall on the floor of the bait station and subsequently become temporarily entrapped in the pest's feet or paws.
Whether caught in the pest's fur or feet or paws, these uneaten pieces of bait are carried out of the bait station and then broadcast to surrounding areas when they fall off of the pest. In large enough amounts, these uneaten pieces of bait can harm other non-target animals. This is particularly problematic for free range farms. For non-limiting example, free range chickens or free range swine may confuse the pieces of uneaten bait on the ground as feed stuffs and consume the same.
Heretofore, the only option to minimize the risk of the bait being eaten by non-target animals is to forego the use of bait stations entirely, in favor of other devices such as mechanical traps or the like. Such mechanical traps or the like, however, are not as effective as the bait stations themselves as they are more costly, require frequent removal of trapped pests, and can be harmful to humans, depending on the size of the trap.
Accordingly, there is a need in the art for a bait station that reduces or entirely eliminates any unintended broadcasting of bait outside of the housing of the bait station. The invention provides such a bait station. These and other advantages of the invention, as well as additional inventive features, will be apparent from the description of the invention provided herein.
In one aspect, the invention provides bait station for containing bait. An embodiment of such a bait station includes a housing enclosing an interior space and defining at least one opening permitting access to the interior space from an exterior of the housing. This embodiment also includes a floor member situated within the interior space and elevated above a bottom wall of the housing. The floor member includes a plurality of openings configured to allow pieces of said bait to pass through said openings such that the pieces of said bait are contained within a containment space below the floor member and above the bottom wall of the housing.
In an embodiment according to this aspect, the plurality of openings are formed between a plurality of slats of the floor member. The floor member can include one or more supports extending outwardly from said floor member.

The extension portion includes at least one passage configured to allow a bait rod to extend through the at least one passage.
In an embodiment according to this aspect, the bait station also includes a tray interposed between the floor member and the bottom wall. The tray and floor member are snap-fit together such that the tray and floor member are removable as a unit from the bait station.
In an embodiment according to this aspect, the tray includes a base portion, an extension portion, and an upright portion. The upright portion of the tray extends generally perpendicular to the base portion of the tray. The extension portion of the tray extends generally parallel to the base portion of the tray. The extension portion of the tray includes at least one passage configured to allow a bait rod to extend through the at least one passage.
In another aspect, the invention provides a bait station for containing bait. An embodiment of such a bait station includes a housing enclosing an interior space and defining at least one opening permitting access to the interior space from an exterior of the housing. This embodiment also includes an insert that is removable from the housing. The insert includes a tray and a floor member spaced from the tray such that a containment space is provided between the floor member and the tray.
In an embodiment according to this aspect, the housing includes a lid connected via at least one hinge to a body of the housing that is movable between an open position and closed position. In an embodiment according to this aspect, the housing includes at least one lock configured to lock the lid in the closed position. In an embodiment according to this aspect, the at least one opening is sized to allow passage of an adult rodent into the interior space.
In yet another aspect, the invention provides an insert for a bait station for containing bait. The bait station includes a housing that encloses an interior space and provides at least one opening permitting access to the interior space from an exterior of the housing. The insert includes a tray and a floor member spaced from the tray such that a containment space is provided between the floor member and the tray. The tray and floor member are configured such that they are removable as a unit from the interior space of the housing.
In an embodiment according to this aspect, the floor member includes a plurality of openings configured to allow pieces of said bait to pass through said openings such that the pieces of said bait are contained within the containment space below the floor member and above the bottom wall of the housing. The plurality of openings are formed between a plurality of slats of the floor member. The floor member includes one or more supports extending outwardly from said floor member. The supports are L-shaped.
In an embodiment according to this aspect, the floor member includes a base portion, an extension portion, and an upright portion. The upright portion of the floor member extends generally perpendicular to the base portion of the floor member. The extension portion extends generally parallel to the base portion of the floor member.
In an embodiment according to this aspect, the tray includes a base portion, an extension portion, and an upright portion. The upright portion of the tray extends generally perpendicular to the base portion of the tray. The extension portion of the tray extends generally parallel to the base portion of the tray.
Other aspects, objectives and advantages of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
The accompanying drawings incorporated in and forming a part of the specification illustrate several aspects of the present invention and, together with the description, serve to explain the principles of the invention. In the drawings:
While the invention will be described in connection with certain preferred embodiments, there is no intent to limit it to those embodiments. On the contrary, the intent is to cover all alternatives, modifications and equivalents as included within the spirit and scope of the invention as defined by the appended claims.
Turning now to the drawings, an exemplary embodiment of a bait station 20 and an insert 30 for such a bait station constructed in accordance with the teachings of the invention are illustrated.
In
Insert 30 is situated in interior space 32 as shown. As may be derived from inspection of
Turning now to
Floor member 50 includes a plurality of openings 60 formed between adjacent slats of floor member 50 as shown. It is these openings which permit passage of the aforementioned uneaten pieces of bait. While shown as generally rectangular in shape due to the shape and arrangement of the slats, openings 60 may take on any other suitable form, such as for non-limiting examples circular perforations, etc. Indeed, any shape is sufficient which on the one hand will not inhibit the target-animal's ingress and egress from bait station 20, while on the other hand will allow for passage of the uneaten pieces of bait.
Floor member 50 also includes an upright portion 54, a base portion 56, and an extension portion 58. Upright portion 54 is generally perpendicular to base portion 56, and extension portion 58 is generally parallel to base portion 56. Similarly, tray 52 includes an upright portion 64, a base portion 66, and an extension portion 68. Upright portion 64 is generally perpendicular to base portion 66, and extension portion 68 is generally parallel to base portion 66. Further, each of floor member 50 and tray 52 include one or more passages 62, 72, respectively, which allow for passage of posts 40 vertically through insert 30 to elevate bait above floor member 50.
Turning now to
In the illustrated embodiment, openings 60 are arranged such that they will be below and on the side of the target animal when the target animal is situated on floor member 50. This configuration not only serves to capture uneaten pieces of bait falling directly below the target animal, but also those pieces which may be trapped on the target animal's body. For example, as the target animal travels along base portion 54 to leave housing 22, it will rub against upright portion 54, and uneaten pieces of bait will also pass through the openings 60 in this region.
Still referring to

Floor member 50 is illustrated in
With such an alternative configuration, and referring momentarily back to
As such, it is contemplated by the teachings herein that tray 52 is an optional component and need not be present to practice the invention. Rather, all that is required is a floor member such as floor member 50 having integrated supports 92 or any other provision which would elevate the same above the bottom wall of housing 22 to thereby bound and define a containment space for capturing uneaten pieces of bait. However, use of the tray 50 provides the additional advantage of being able to easily remove the entire insert 30 as a unit from interior space 32, separate floor member 50 from tray 52, and invert tray 52 to dump out and dispose of uneaten pieces of bait captured by tray 52. Without tray 52, the entirety of bait station 20 needs to be manipulated with or without floor member 50 situated therein to dispose of uneaten pieces of bait captured thereby.
Further, when embodied as an insert such as insert 30 as illustrated, the same may be integrated with existing bait stations already in place. Indeed, insert 30 may be manufactured so as to assume the peripheral space of an interior space of an existing bait station and then retrofit therein. Many contemporary bait stations include a lid providing access to their corresponding interior space, so it is only a matter of ensuring that insert 30 can be dropped in place within the interior space. Such a configuration allows a site, such as a large agricultural operation, to enjoy the advantages of the invention described herein, without the necessity of fully replacing their existing bait stations.
