One thing to think about is the treated wood you use today is different then the old stuff. I think OSHA did something about it the chemicals being used.
They don't use Arsenic since 2003 because it is a Hazardous Substance.
I remember building stuff outside with treated wood and it would last a long time... no rot and no bugs. The stuff I bought 2008 is useless because the Carpenter Bees don't have any problems with the new stuff.
Your right about the Carpenter Bee's, mind has been up about 3 years, I am finding holes in the treated 6x6's, so I have been filling the holes with black oil base paint, they seem to love it because they are not eating holes in the wood anymore.
