Abstract: A reusable trap capable of trapping rodents alive is self-locking. The trap comprises an elongated tube with a first terminus entry opening and a second terminus having a moveable closure door. A trapping door and latch means are mounted within the elongated tube in a manner which allows the trapping door to swing inwardly towards the second terminus by a pushing force supplied by the rodent. The latching means ensures that the trapping door cannot fully swing outwardly towards the first terminus nor can the door be pulled inwardly. A support member secured to the elongated tube at or near the second terminus elevates the second terminus and provides a slightly upwardly slope towards the second terminus when the trap is placed on a horizontal surface. The upward slope enhances the initial appeal of the bait and the trap to the rodent.
