A three-sided molded elongated hollow body consisting of opaque plastic material and defining a channelled front merging into a channelled top and a pair of channelled sides and forming a closable animal entrance, a transparent plastic trap door movably mounted on the body for controlling the animal entrance, a transparent plastic rear closure detachably connected to the top and the sides, a transparent plastic bottom detachably connected to the rear closure and to the sides to define a box-like structure, and a single wire trip engageable with the trap door and actuatable by an animal entering the body to release the trap door effecting closure of the animal entrance thereby.

A single use disposable animal trap particularly suited for entrapment of rodents and the like, the invention comprises a housing of dimensions only slightly greater than the site of the animal which is to be trapped, the housing having an entrance opening and a pivoting inclined plane mounted internally of the housing. An animal entering the trap biases a rear portion of the inclined plane downwardly, a forward portion of the inclined plane thereby camming a door member into place over the entrance opening. In a preferred embodiment, a shoulder-like detent formed on the inner wall of the door member abuts a forward edge portion of the inclined plane, thereby to maintain the door member in place over the entrance opening and to prevent escape of the animal from the trap.

A rodent trap comprised of an enclosure having a hinged lid for sealing the enclosure and an automatic closing mechanism for automatically closing the lid when a rodent enters the trap. The closing mechanism is comprised of a platform in the enclosure and a latch means for latching the platform in a fixed position. The latch is connected to the lid so that weight applied to the platform trips the latch and closes the lid sealing the container and trapping the rodent inside the enclosure.

Simplified molding of a disposable plastic mousetrap is achieved by providing an elongated box and a triggerable closure hinged to the box along a hinge axis parallel to the direction of elongation. Shield means prevent access to the trigger from the exterior of the box, thereby requiring the mouse to enter the box before reaching the trigger.

A trap for capturing animals comprising a main box, step boards, doors and anchoring members. The step boards are pivotally held to the main box, and the anchoring members attached to the step boards are designed so as to keep the doors open by anchoring them. When the step boards are pressed down by the weight of an animal passing through the main box, the doors are released from the engagement with the anchoring members and caused to close the entrances to confine the animal in the main box. Since the animal trap of the invention needs no bait for capturing an animal, it may be set up without any difficulty on the running route of the animals.
