Abstract: Provided herein is an efficient rodent trap device, where the rodent, such as a mouse or a rat, is killed, when the rodent is moving through the rodent trap. The rodent trap includes at least one rodent passage, a trigger mechanism and a killing mechanism. The rodent passage includes a first outer opening and a second outer opening arranged at opposite ends of the rodent passage. The openings provide entries from ambient surroundings. In use, the rodent is led into the trap through the one or the other opening. The trigger mechanism includes one sensor and another sensor, the one sensor arranged between the killing mechanism and the first outer opening and the other sensor is arranged between the killing mechanism and the second outer opening. The killing mechanism includes at least one killing element, which in use enters said rodent passage between the sensors and when actuated by the killing mechanism.
