A carpenter bee trap is provided to aid in the protection of structures from carpenter bee infestation. The carpenter bee trap includes an enclosure with an interior that is divided into an entrance chamber and a trap chamber by a divider. A portion of the enclosure is adapted to allow ambient light to enter the trap chamber, and the divider is sized and positioned so as to provide a gap that allows ambient light to enter the entrance chamber and that also allows bees to access the trap chamber from the entrance chamber. At least one hole extends from an outside surface of the enclosure to the entrance chamber and acts as a primary attractant for carpenter bees. Once bees enter the entrance chamber through the hole(s), they are attracted to the ambient light in the trap chamber, where they are trapped. A portion of the enclosure is preferably adapted to allow easy access to the trap chamber for removing the trapped bees.
