Device for combatting rodents

A device for combatting rodents, the combination comprising an elongated tunnel whose axis is generally horizontal in use of the device, said tunnel being of such size and shape that it permits the passage of a rodent to be poisoned therethrough, a poisoned bait container whose axis is generally vertical in use of the device, said bait container being joined to said tunnel and positioned approximately centrally with respect to the axis of said tunnel, the axis of said container being offset from the axis of said tunnel such that the area of juncture between said tunnel and said container involves a substantial portion but less than all of the cross-sectional areas of said tunnel and of said container, said container and said tunnel being in open communication with each other at their region of juncture, said bait containing extending above said tunnel, and a supply of poisoned bait in said container located therein above said tunnel so that said bait spills out of the open end of said container into an unobstructed uncontained loose sloped pile that partially obstructs the cross-sectional area of said tunnel, whereby a rodent passing through said tunnel either eats some bait from said pile or else at least physically contacts the sloped pile of bait obstructing its passage through said tunnel so as to be later poisoned upon grooming itself by the poisoned bait adhering to its body.
