A housing has an entrance space into which the mouse enters. A pair of touchplates are embedded in the floor of that space, and when he steps on them, he bridges them and energizes a circuit for operating a pusher plate for pushing the mouse from the entrance space into a pit, where he is confined alive. A space is provided for bait at such location that the mouse is pushed into the pit before he can reach the bait. The pusher plate is actuated by a solenoid in a main circuit activated by a control that itself is energized by the presence of a mouse.
