Abstract: A tunnel trap comprising an elongated tubular housing, a rear cover closing the housing rear end and a door pivotally mounted adjacent the front end of the housing. The door is pivotally mounted for movement between an open position permitting access to the housing interior and a closed position closing access to the housing interior from the front end. Springs bias the door towards the closed position. Latches releasably engage the door to maintain the door in an open position against the bias of the springs or in a closed position for locking the door. A trigger mechanism is coupled to the latch maintaining the door open to release such latch permitting movement of the door towards its closed position.
