Abstract: A disposable animal trap for pests, such as mice and rats, comprising pivotal top and bottom members which are spring loaded and which form a retentive enclosure when triggered. The triggering mechanism is the bait itself which is solid and preferably edible and which supports the top and bottom members in an open, animal inviting, position and which triggers the closure of the members when eaten, collapsed, or moved, to retain the pest. The spring may be integral with the top member or a common rubber band may be used as the spring. The top and bottom closure members are preferably made of a high impact molded plastic to resist the gnawing and clawing action of the animal, as well as for cost efficiency.
