beetles in cedar logs

I recently built a canopy bed and several other pieces of furniture from cedar logs and limbs and have now discovered the trees are infested with beetles. Some of the pieces are still raw, but the bed and a few chairs have been coated with polyurethane. From what i’ve read, i assume i’ll have to strip the coated pieces in order to treat them. Also have 20 or 30 cedar logs 12 to 14 feet long and 6 to 10 inches in diameter. Would it be best to mill the logs into lumber then treat the boards or could i treat them while their still logs.

First, you are right in that you will need to remove the polyurethane first from the cedar bed and chairs in order to allow the BORACARE treatment to penetrate. Second, it’s almost always a sure thing that the thinner the wood being treated, the better your application will penetrate. But could you treat the logs without having the mill them first? Absolutely.

As a general rule, Boracare will penetrate through 4″ well so anything wider than 8″ will be risky even if you treat from all sides. That being said, if you are sure the logs are free of beetles to start with, this probably won’t matter.
