I have 3 surfaces that I can treat. Possible wood beetles? I was thinking of drilling a series of ¼ dia c 2' deep holes at random and filling with Bora-Care solution or a product that you can recommend and then plug holes at a later date. Thanking you in advance.
Bora-Care would be the best product to use, applied twice to the three surfaces you can get to. It will penetrate up to 4 inches with 1 application, and up to 8 with 2. If you choose to drill you should drill whatever size hole you need based on what you have available to inject the Bora-care with. Typically if you have an injection piece of equipment, 1/4 inch or 1/8 inch holes are used. Please see this technical bulletin from the manufacturers of Bora-Care that explains about drilling and injecting into wood. See page 5 and it will give specifics about the drill pattern, etc. Bora-Care Remedial Technical Bulletin
