Do Carpenter Bees Sting?

Yes, but only females sting. They will only sting if agitated. As for the males they are really just alive for reproduction. They will chase anything airborne mistaking the object for a female carpenter bee. The myth that carpenter bees don't sting was probably started because there are more female than male bees, and since only females sting the chances are small that you will get stung, but the sting of a carpenter bee is usually worse than other bee stings. - John Baskin
