Abstract: With reference to a preferred embodiment as depicted in FIG. 4, the present invention provides a mousetrap comprising a first part (5) and a second part (10) that together define an enclosure wherein the first part (5) and the second part (10) are operably connected to a first biasing means (60). Within the enclosure is retained a lever (45) having a first end (47), a bridge (49), a pivot means (40), a releasable catch means (57) and a second biasing means (55). The second biasing means (55) biases the lever (45) into a resting position. By virtue of the second biasing means (55), the mousetrap is able to be set when held in any orientation, and is also stabilised (i.e, accidental activation of the mousetrap is avoided, or at least minimised, when the mousetrap is turned in any orientation, for example, on its side or upside down).
