I am planning to use in my house. I have removed the boards from the barn and there were signs of termites there. I pressure washed the boards, sun dried them for 3 days, steam cleaned the boards and sprayed the boards with Otho Home Defense, not the Max version multiple times. Does anyone have any other suggestions for treatment before I install them?
It looks like you have taken more than enough precautions to eliminate a termite problem. They probably would not have survived being moved into the dry interior environment. I hope you did not destroy the natural look of the barn boards.
