Abstract: A rodent trap is disclosed having a pivotally mounted bait carrier with a catch hole, a cam surface and a magnetic flap biased to an initial trap setting position by a magnet. Thumb pressure is applied to a spring-biased striking bar comprising a major loop and a minor loop wherein the end of a trigger-setting arm is caused to bear down on the cam surface thereby pivotally moving the bait carrier flap substantially from the effect of the magnet and the trigger arm end enters the catch hole and sets the trap.An alternative bait carrier is disclosed which is mounted to the base for wobbly movement so that the lateral as well as vertical movements of the bait arm are effective to spring the trap. The bait carrier and trigger setting arm end cooperatively engage in such a manner as to automatically align the wobbly bait carrier during the trap setting procedure.
