Abstract: A multi-purpose pest trap characterized by a container including a rodent trap portion and a bug trap portion. The passage of the rodent into the rodent trap portion towards a bait supply interrupts a photoelectric beam and causes the entry to the rodent trap portion to be closed. Thereafter, a movable partition defining a gas chamber is closed, where the rodent is then effectively eradicated by a gas discharge. In the bug trap portion, a pivotal chute directs the bug onto a rotatable brush disposed within a gas chamber. The aforesaid chute pivots and the brush rotates upon the interruption of a photoelectric beam when a bug is at a bait location. Again, gas discharge serves bug eradication.
