ABSTRACT:
An automatic rat killing device includes a box having an opening at its top and a stairway leading to its top. A pair of closure plates are pivotally mounted at their one ends on the box for movement between horizontal positions where the two closure plates are mated together at their other ends to close the opening and vertical positions where the closure plates are separated apart to open the opening. A solenoid is mounted on the box and has a stop lever normally engaged with the closure plates to hold them in their horizontal positions. A container holding a viscous liquid is removably accommodated within the box. A detector generates a detecting signal when a rat touches a bait. The solenoid is energized to move the stop lever out of engagement with the closure member so that the closure plates are moved to their vertical positions, thereby causing the rat to fall into the viscous liquid. A returning mechanism is operable to return the closure plates to their horizontal positions whereafter the stop lever is moved to engage the closure plates to retain them in their horizontal positions.
