A reusable or disposable rodent trap, having only two discrete parts, consisting of an unstable, tiltable enclosure, upon whose exterior surface is mounted a rotating door member with elongated side panels, which is prevented from rotating whenever the entrance side of the enclosure is downwardly inclined. Contact between the elongated door side panels, and the surface upon which the downwardly inclined enclosure rests, provides the rotational impediment. A rodent traversing the length of the enclosure to reach bait at the closed end causes the enclosure to incline upwardly, allowing the door to rotate closed by gravity. The rodent's return to the entrance end causes the enclosure to again assume a downward inclination. Since the door cannot be rotated in either direction when the enclosure is downwardly inclined, the rodent cannot open the door when proximate to it. The rodent, which will die of asphyxiation within hours, may be disposed of by simply inverting the trap.
