Can carpenter bees sting you?
The short answer is:
Yes, females carpenter bees can sting, although carpenter bees are not known to be aggressive species. If you are seemingly being followed, chased, or investigated by a carpenter bee, it's probably a male (for reasons explained below). Male carpenter bees cannot sting.
Not only do we know that carpenter bees can sting, we also have an idea about how painful it is in comparison with some other stinging insects, like wasps and other bees.
How do we know? Because scientific research has explored this topics.
If you are feeling intimidated by large carpenter bees, the following information may put your mind at rest.
The most painful bee sting we know about, happens to be the sting of a tropical large carpenter bee species, Xylocopa latipes, also known as the tropical carpenter bee or 'giant Bornean bee'. It's found in Southeast Asia, so if you live in Europe or the US, for example, it's not something to worry about.
But even if you were stung by this species, would it hurt that much?
According to the Schmidt Sting Pain Index1, despite being the most painful bee sting recorded, the giant Bornean carpenter bee only scores mid-way on the pain scale. The California and Nocturnal carpenter bees are a little less painful than that.
The table below extracted from data supplied by the Schmidt Pain Index, provides the recorded pain score for 3 carpenter bee species.
Additionally, I have added scores for insects with one of the most painful and least painful stings for the comparison, along with the sting pain score for the honey bee for further context:
|Social Wasp||4||Most Painful Sting|
(giant Bornean bee)
(Western honey bee)
(nocturnal carpenter bee)
(California carpenter bee)
(giant sweat bee)
|Solitary Bee||0.5||Least Painful Sting|
I receive queries of this nature from time to time. From the descriptions received, in each case the culprit was a male carpenter bee.
These are quite large, burly bees, and it's easy to feel a little intimidated, yet despite the bee's apparent forthright invasion of your space, it's actually quite harmless, and is investigating to find out whether you are a threat. You can learn more about this on my page about carpenter bees.
Despite having no sting, this brave little creature is determined to protect a carpenter nest, and its territory.
