Large, black bees with yellow markings
United Exterminating Company
In the late-spring and early summer, homeowners often notice large, black bees hovering around the outside of their homes. These are probably [ carpenter bees ] searching for mates and favorable sites to construct their nests.
Male Valley carpenter bee, varipuncla Patton
Male carpenter bees are quite aggressive, often hovering in front of people who are around the nests. The males are quite harmless, however, since they lack stingers. Female carpenter bees can inflict a painful sting but seldom will unless they are handled or molested.
Carpenter bees resemble bumble bees, but the upper surface of their abdomen is bare and shiny black; [ bumble bees ] however, have a hairy abdomen with at least some yellow markings.
