They are also the supports for the deck railing. I just took the cap boards off the railing, and the centers of the 6 x 6s are rotten down to about 3 to 5 inches. I’m not sure if it’s just rot, or if carpenter ants have been in it.

I was going to pour ant poison and wood preservative into the holes. Then maybe fill the holes with something. What should I use to fill the holes? These 6 x 6s are anywhere from 6 to 16 feet in length, and go into the ground 30”, and are set in concrete. They are very very solid. They have been in place 35 years.
Any advice appreciated.
Thanks
