a base having a bottom wall with an upwardly protruding exterior wall having portions defining at least one rodent access opening, and at least one bait compartment base wall which extends upwardly from the base bottom wall, wherein the at least one bait compartment base wall has portions which define a bait compartment for portions of the sachet bait package;
a pin extending upwardly from the bottom wall within the bait compartment, wherein the pin extends through the sachet bait;
a lid connected to the base by a hinge and moveable between a first position which permits direct access to the bait compartment, and a second position in which a top wall overlies the bait compartment, the lid having at least one bait compartment lid wall which is aligned with the at least one bait compartment base wall, the lid being closed on the base in the second position such that the at least one bait compartment lid wall overlies the at least one bait compartment base wall with the sachet bait flap extending therebetween;
portions of the at least one bait compartment base wall which define a multiplicity of upwardly protruding teeth which extend to an uppermost first margin;
portions of the at least one bait compartment lid wall which define a multiplicity of downwardly protruding teeth which extend downwardly below the level of the first margin, wherein in the second position, the downwardly protruding teeth cooperate with the upwardly protruding teeth to frictionally grip a portion of the bait package flap which is wrapped around the base upwardly protruding teeth; and
wherein none of the downwardly protruding teeth or the upwardly protruding teeth penetrate the bait package flap.
