Abstract
A bait station for containing rat poison contains a housing; at least one opening in the housing for a rat to enter; and a bait position in the housing for locating poisoned bait. A divider is provided between the bait position and each opening to prevent direct access to the bait from the opening, for example by a child. However, there are at least two different routes from the bait position leading to openings. Research has shown that rats, unlike mice, prefer not to eat in a confined space and it is believed that the choice of escape routes offered by the bait station of the invention encourages a rat to eat more of the bait. The bait station may include a hinged lid with locking means to prevent tampering with the bait.
Claims13
A bait station for containing poison bait for rats, said bait station comprising
- a housing comprising a base, opposed walls upstanding from the base, and a cover over said walls defining an enclosure, said housing additionally comprising a first portion in said enclosure a rat bait position located in said first portion and a second portion in enclosure and a second portion in said enclosure laterally spaced from said first portions,
- first and second openings in respective opposed walls in the second portion of the housing, said openings extending upwardly from said base, said first and second openings having a substantially unobstructed line of view therebetween and providing entrance and exit passages to or from the exterior of the housing for a rat into and out of said second portion of said housing,
- a divider comprising a wall upstanding from said base to said cover between said first and second portions, said divider having opposed ends;
- a pair of spaces between the opposed ends of the divider and the respective opposed walls of the housing, said divider in said enclosure defining first and second separate generally parallel passageways for a rat in said first and second portions, respectively, and said pair of opposed spaces defining entrance and exit passages between said first and second passageways to provide multiple paths of entrance and escape for a rat to and from the bait position, said first passageway leading from said spaces to said bait and said second passageway extending between said openings and leading to said first passageway by way of said first and second openings;
- and
- upstanding walls along said first passageway and spaced laterally from said divider wall to define a feeding area spaced laterally from said first passageway and accessible only from said first passage.
A bait station for containing rodent poison, said bait station comprising a housing, an opening in the housing, a cover on said housing, and lock means between said cover and said housing for releasably locking said cover to said housing, said lock means comprising two opposed adjacent pairs of barbs extending from said cover, and two opposed adjacent pairs of ledges in said housing, said barbs being resiliently lockable against said ledges, and a key for unlocking said barbs from said ledges, said key having ends and a longitudinal axis, a pair of lobes at one end of the key, said key being insertable in said opening and rotatable around its longitudinal axis to exchange said lobes with the barbs and to simultaneously release all of said barbs from said ledges.
A bait station for containing poison bait for rats, said bait station comprising an enclosure including a base, a cover and opposed side walls, a first portion and a second portion in said enclosure, a pair of spaced openings in said opposed side walls in said second portion of said enclosure, with a clear line of sight between said openings, a divider between the first and second portions of said enclosure, said divider extending substantially parallel to said line of sight, said divider defining first and second passageways for a rat in said first and second portions, respectively, at least first and second spaced openings around said divider defining entrance and exit openings for a rat between said first and second passageways, and upstanding walls along said first passageway and spaced laterally from said divider wall to define a feeding area spaced laterally from said first passageway and accessible only from said first passage whereby the rat has multiple avenues of entrance and escape to and from the feeding area.
