An animal trap has a housing (2) and a support (12) extending within the housing. The support is movable between a first, set position and a second, fired position. A trigger (6) is integrally formed with the support (12) and protrudes from the bottom of the housing in the set position. Wire loops (4), which act to kill an animal, are fixed to the bottom of the support (12) and also protrude downwardly. In the set position of the trap, shoulders (18) on the trigger (6) are engaged beneath flanges (20) formed on the bottom of the housing. These shoulders (18) and flanges (20) form interengaging means to hold the trigger (6) and the support (12) in the downwardly extending set position against the force of two torsion springs (22) which are each affixed to the bottom of the support (12) and to the housing (2). The trigger (6) can be moved by an animal due to its flexibility. This causes the interengaging means to become unengaged and the support (12) to move explosively to its upper fired position. The movement of the support explosively lifts the wire loops (4) whereby an animal within a loop is squashed against the bottom of the housing.
