Why do I see all these bumble bees around the Visitor Center at William B. Umstead State Park?

Great question! The bulbous bees you are seeing are not the American bumble bee (or Bombus impatiens - pretty fun to say don’t you think?), but rather are the eastern carpenter bee (or Xylocopa virginica). 

Carpenter bees are notorious for, as their name suggests, doing carpentry work (so to speak), on the environment around them. The female carpenter bee uses her POWERFUL jaws to excavate through wood mediums, such as trees, wooden porches, or our houses, to create circular orifices in which to lay her eggs. She also places pollen with the eggs for the hatchlings to consume once hatched. These eggs are then defended by the males of the species. This teamwork between the mated pair increase the chances of viable offspring. The bees hibernate during the winter and are active from spring through early fall. The males are not known to sting, although the females may if provoked. 

The female carpenter bee burrows through wood, but the wood is not a carpenter bee’s diet. Carpenter bees consume nectar from flowering plants. Because of this, they are some of our greatest pollinators. A healthy prospering garden is one with all varieties of pollinators including carpenter bees. Understandably, though, many people do not care for carpenter bees to be present near their homes and other man-made wooden structures.

Though they do little damage in the way of structural weakening short-term, many view the wood burrowing carpenter bee as a nuisance. A way to steer the carpenter bee away from your man-made structures is by using treated or painted wood. Another means to deter the carpenter bee is to seal up the existing holes as soon as the bees emerge in the spring and use an almond oil or citrus oil spray on the area.

Carpenter bees are fun and exciting creatures to watch, take a moment to watch their patterns and ponder their place in our wild and wonder-filled world.
