Abstract
An alarm housing for a rodent control device such as a spring actuated trap. A frame with opposed side and end members defining a trap opening for receiving the trap, and an electrical switch mounted in the frame so that positioning of the trap in the frame moves the switch to one circuit condition. Tripping of the trap by a rodent produces a lifting action which moves the trap upward out of the frame permitting the electrical switch to move to the opposite circuit condition thereby providing an indication of actuation of the trap.
