If there is one piece of advice we give to every barn buyer it is: DO NOT BUY A BARN FRAME THAT IS NOT PROPERLY FUMIGATED! If you do, you are looking for big trouble from some very little bugs, like powder post beetles. We fumigate all our barn frames before assembly.
It can be over twenty times more expensive to fumigate these stubborn pests when they are in your finished barn home and you need to move out of your house and have a fumigation company tent your entire house in order to fumigate it. We have licensed in-house fumigators on our staff and every one of our barns is thoroughly treated before it leaves our yard with a fumigant that has no residual effect.
