  • a compartment defined by one or more walls, said compartment comprising an inlet for receiving a rodent
  • triggering means for triggering said mechanical killing arrangement, said triggering means comprising at least one sensor configured for detecting a rodent in said compartment, and
  • the compartment defined by one or more walls is to be understood as an inner space of the trap into which the rodent may move.
  • the compartment is arranged such that the width of the compartment is not too large compared to the width of the rodent.
  • an advantageous situation may arise, where the path of the rodent is sufficiently fixed with respect to the transversal position of said compartment, and such that said at least one sensor will detect the rodent in a specific transversal position in the compartment.
  • a mechanical killing arrangement is to be understood an arrangement adapted to performing killing of rodents by mechanical killing means.
  • Such mechanical killing means may kill the rodent by means of striking, stabbing, cutting or otherwise inflicting physical damage to the rodent.
  • the mechanical killing element may be a blunt object inflicting blunt force trauma, or a sharp or pointed object inflicting penetrating damage.
  • An advantage of the trap being provided with a disposal arrangement is that the trap may automatically dispose dead rodents from the compartment of the trap, thereby allowing passage through the compartment for further rodents. Furthermore, since trap is automatically reloaded after killing a rodent, it may kill the further rodent passing through the trap. Hereby a more effective trap for killing rodents is provided, especially for areas with a density of rodents. Also, since the rodents instantly or at least within a matter of few seconds, the rodents will not move to an unknown position outside the trap before dying, but will be located in the trap. Another advantageous effect of the trap according to the invention is that it accumulates the dead rodents in or at least near the trap. Thereby, the dead rodents may easily be collected in said container and disposed.
  • the killing element is a blunt object inflicting substantially non-penetrating and blunt force trauma.
  • An advantage of this aspect is that the dead rodent is substantially un-penetrated, i.e. the dead rodent leaks substantially no blood or intestines. Thereby, only a minimum of cleaning of the trap is necessary.
  • said container is a bag.
  • a bag such as a plastic bag, may more easily be replaced.
  • said bag since it is flexible, it may be easier to open and close thereby providing a re-closeable container for receiving dead rodents.
