I have a house in a rural area that gets attacked every year by carpenter
bees. The fascia boards (1x10's) on the eaves are cedar and the bees
tunnel into these boards so much that many of the boards need to be
replaced. If you have never seen this let me tell you, they make 1/2
diameter tunnels that go through the cedar into the framing, or turn
horizontal and go for 6 to 12 inches. Some boards are so eaten up that they
are structurally unsound.

Anybody go any ideas about what I could use to replace the boards with that
would deter the bees? The house is all rough wood on the outside so I
would rather not replace these boards with something that looks artificial.
I have tried plugging the holes, insect spray and using a racquet ball
racquet to discourage them but there are too many bees.

Actually, standing on the roof and smacking them in flight is pretty sporty
and satisfying but too time consuming.

Thanks for your comments,
