Bora-Care is not labeled for use to target borers on plants or trees, and it only intended to be used on cellulosic materials including wood, plywood, particle board, paper, oriented strand board (OSB), cardboard, and wood composite structural components. You may consider using Tenguard SFR Termiticide which is labeled for use on on fruit and nut trees around residential sites to target Peachtree Borers, but we would recommend reaching out to your local cooperative extension office for recommendations on products to target Shot Hole Borers.
Bora-Care is only applied to raw untreated cut wood, it would not be applied to straw and we are not aware of anything that can be used to treat it.
Bora-Care will not penetrate through logs that still have bark on them. The bark will need to be removed from each log for an effective application. If the sleepers are 8-10" in diameter, this will require 2 full applications. The second application will need to be applied once the first application has dried.
Since you are wanting the joists to be treated as well, we recommend spraying the Boracare directly onto them as it will not soak through the floorboards into the joists. Boracare may take time to get throughthe floorboards since the wood is very old and would not have much moisture remaining in them. The best way to be sure the Boracare penetrates correctly would be to treat on all sides and get a full coverage spray.
Yes, if the glue is not holding with the Bora-Care on the surface we recommended sanding before applying the glue.
According to the manufacturer, both, Bora-Care and Bora-Care with Mold-Care can be applied to pressure treated wood, but because Bora-Care with Mold-Care uses the 5:1 ratio it will take much longer for the product to absorb into the wood.
In general, the questions you are asking are a bit of an overthink on how to use this product. Boracare can be sprayed, painted/brushed, or rolled onto wood and should be done so in a way that the wood surface is wet but not dripping the product off. The angle of spray, nozzle pattern, droplet size, and distance make no difference. If you will be applying in freezing temperatures its best to hold off on the Boracare application as the cold could inhibit it from penetrating into the wood fully and correctly. Ideally you would need the air temperatures and wood to not be frozen even if the Boracare solution itself is warm. If you have any additional questions about the application of the Boracare you can always call Nisus directly at 800-264-0870.
We strongly recommend referring to Table A, Table B & Table C on the actual product label for Bora Care to calculate how many gallons you'll need based on your specific application purposes. You may also contact the manufacturer directly with specific product application questions at 1-800-264-0870 or via their website's contact page here. Please let us know if we can further assist with general product information or placing an order, as we are a distributor of this product.
We apologize but that is not a question that has ever come up, and not something we feel would be safe if the horses are going to be inhaling or ingesting the sawdust materials. We would suggest not using any sawdust from a Boracare application in those areas, but you can contact the manufacturer Nisus directly to go over any concerns you may have in detail. You can reach them at 800-264-0870.
It is recommended to wait until the application of Bora-Care has completely dried throughout the treated wood before sanding or applying any type of paint, stain or sealant. Depending on the humidity or moisture in the wood, this can take 24-48 hours to dry. For best results, applying a stain, paint or sealant should be done within 30 days of the Bora-Care application.
You can definitely use a product like Bora-Care to treat for the life of the 3" thick piece of raw wood. You may also apply a finishing or paint over the wood once it dries. Usually dry time is about 72 hours.
Bora-Care can be applied to any raw wood that does not have a paint, stain, or finish on it. Please be sure to review the product label for more information and complete application instructions.
Boracare is not labeled for roaches. It would be best to use products that are specifically labeled for them, such as the ones that are found in our roach control kits.
Boracare is not labeled for carpenter bees. We would recommend our Carpenter Bee Kit for a combination of residual liquid insecticide, insecticide dust and trebor plugs to successfully treat for Carpenter Bees. Please review the Carpenter Bee Control Guide to see the best tips and products used for eliminating and preventing carpenter bees throughout the season.
Yes, you can apply Bora-Care to wood that has previously been treated with Timbor. The previous application of Timbor will have no affect on the absorption of BoraCare into the wood. Since both products are borate-based and become one with the wood after application, there should not be any issues. You don't need to do anything to the wood unless you had applied any type of paint, sealant or stain after you applied the Timbor. If you had applied a sealant/paint/stain then you would need to strip the wood back down to it's raw state.
To use Bora-Care on stained wood, you would need to either strip and sand the mantle to its raw wood state or drill holes into the piece and use the gel formulation of BoraCare called Jecta. If sanding the wood to its raw state, BoraCare would be applied at the 1:1 ratio and after it has dried you can re-stain/finidh the mantle. Jecta is a ready-to-use injectable borate gel used by pest management professionals to protect sealed or inaccessible wood from termites and other wood-destroying organisms.
Wood treated with BoraCare is able to be painted, stained or sealed within 30-45 days after the application. The color of the wood after staining should not be affected as BoraCare will absorb clear into the wood. Please review the product label for more information.
