Carpenter Bees in Dead Birch Log: No Threat to Living Trees

Identification

Perfect ½-in holes + sawdust = carpenter bees (Xylocopa virginica). They nest in dead, dry wood only.

Carpenter bees do not attack healthy trees. No treatment needed for your grove.

Paint or seal the mailbox post. Fill holes with putty after bees emerge (late summer).
