A Murder Hornet excluder is described. The excluder is made from a mesh that has openings large enough to let both queen and worker bees in and out, but too small to allow the much larger hornets to invade. It has a stepped top, two sides and a bottom that “wrap around” the entrance to a beehive. The stepped top extends the front several inches in front of the opening to the hive to give honeybees a “safe cage”, with adequate room to begin flight and descend after passing through the excluder. In a preferred embodiment, the mesh is between 6 mm and 10 mm on a side.
