The mole trap includes a base assembly and an upper movable frame. Two vertical guide rods are attached to the base assembly and pass through the bores through the upper movable frame. Springs urge the movable frame away from the base. Two U-shaped rods are attached to the movable frame and extend under the base. An upper horizontal pin is fixed to the movable frame. A lower horizontal pin is fixed to the base. A tension link connected to the upper pin. A recess in the link receives the lower pin and holds both springs in loaded condition. A bracket with a tension link recess is pivotally mounted on the lower pin. A tension link release surface on the bracket releases the tension link when a mole sensor pivots the bracket.
