Carpenter bees look like typical bumblebees but often lack
yellow stripes. They are solitary bees.
Unlike bumble bees, carpenter bees are solitary insects. Female
carpenter bees will chew a tunnel into a piece of wood to build a
nest gallery. The bits of wood she chews and deposits outside the
nest are called frass. The male carpenter bee guards the outside of
the nest. He does not have a stinger, but his constant buzzing
causes concern for some.
Carpenter bees bore through soft woods to lay eggs and protect
their larvae as they develop.
Carpenter bees do not pose a public health threat, but they can
damage wood through their nest building.
