Paint the wood a good exterior paint. Here a website that may help.( http://www.getridofthings.com/get-rid-of-carpenter-bees.htm ). If you want to keep the natural wood look there are treatment out there to help just check with your local hardware store to see what they carry. ( Example: http://doyourownpestcontrol.com/carpenter_bees.htm )
That is what the pest guy told me - make sure a good coat of paint is on the wood.
