I have active dry wood termites in thick interior beams inside the house. The beams are exposed and untreated, and it would be possible for me to spray Bora-Care on 3 sides of them. However, the beams are about 10 in x 10 thick.
Bora-Care can be applied to raw, natural wood and penetrate 4 inches into the wood surfaces. It is recommended to apply to all sides of the wood for the best results. You will mix it at a 1:1 ratio for active drywood termites and it should be diluted with hot water in a separate container and mixed completely first. After it is mixed properly, you can add it to your spray tank for application. Please refer to the link below for the application chart based on dimensions. Application Chart Bora-Care can take up to 90 days to completely penetrate through all of the wood to where all of the termites are. Bora-Care does not kill the termites by touch. The termites walking on the wood are not effected. Bora-Care kills the termites by ingestion. After the Bora-Care has moved through the wood, the termites that are still in the wood will die when they continue to eat and ingest the Bora-Care with the wood. You should treat all exposed sides of the wood that you can get to. One treatment is normally enough unless the wood you are treating is more than 8 inches thick. The termites will not spread easily to other areas so that is not a concern. Bora-Care Product Label Drywood Termite Treatment Article
