Including stairs
You can use Bora-Care on any raw wood inside or outside your home, including hardwood floors. However, it can only be applied on raw wood. You CANNOT apply Bora-Care to any wood that is painted, stained, or sealed. So unless your hardwood floors are unfinished, you cannot spray them with Bora-Care. If your flooring is already finished with a stain and sealant, then you either have to sand off the finish and the re-finsh after applying Bora-Care, or you can drill holes into the infested pieces and inject Bora-Care.
