A disposable trap for small animals, such as mice or similar rodents, in which a pair of co-axially slideable, interfitting plastic members, namely a hollow plunger and an outer housing therefor, are biased axially towards one another by means of an axially imposed external force supplied by an elastic band, or the like, operational to move the two members toward each other. The plunger is substantially enclosed on all sides except for an animal entrance to its hollow interior and the outer housing is fully enclosed except for one end into which the plunger co-extensively fits. When the two members are axially collapsed so that the outer housing surrounds the plunger, the animal entrance is closed off to entrap an animal within the interior of the plunger. A flexible cantilever type trigger plate extends from one end of the outer housing into the trapping chamber of the plunger and suitable detent means are provided to maintain such members in their separated or extended condition. When the animal enters the trapping chamber and releases the detent means by depressing the trigger plate, the plunger is moved rapidly into the outer housing which thereupon blocks off the animal entrance, preventing escape. One end wall of the plunger optionally is removable to afford reuse of the trap, if desired.
