Boracare can be used on wood that is pressure treated, but it may take longer to absorb into the wood. In some cases, such as in a pre-construction termite treatment, pressure treated wood must be treated with Boracare. Boracare is preferred over other treatments such as Timbor in treating furniture because Boracare dries clear and will leave the furniture in its natural state. It will also absorb much further into the wood so you know the infestation is treated. Boracare is diluted with water at a 1:1 - 1:5 ratio depending on the pest you are targeting.
Bora-Care can be applied to any raw wood that is not painted, stained or sealed so yes it can be brushed on to the underside of the flooring. It will only prevent termites from entering the wood that it is applied to and will penetrate up to 4 inches with one application. It should be applied until the wood is just wet but not dripping. Most of the time termites would have to eat through the sub-floor to get into the hardwood floors above, but there is no 100% guarantee that the termites will enter this way. Treating the sub-floor would also ensure the termites do not get into the sub-floor as well. If you want the hardwood floors better protected, you should treat all exposed wood also as long as they are unfinished. Please see page 10 of the Bora-Care label. Table A on page 10 will tell you how many lineal feet of board the bora-care will treat based on thickness. The tabel tells you how many lineal feet a DILUTED gallon will treat
The Bora-Care is currently only available in the gallon size.
No, Boracare is not labeled for carpenter bees.
For carpenter bees, we would recommend using our Carpenter Bee Kit. It has everything you need to do a complete treatment for bees.
Please also check out our Carpenter Bee Guide for more tips on how to treat and prevent them in the future.
We would recommend giving the Bora-Care at least 24 to 48 hours to dry completely. Factors that could prevent the Boracare from drying complete within that time frame include applying to finished or treated wood, failing to mix the product completely before application, mixing too much Boracare concentrate for the amount of water (less than 1:1 dilution), or extreme weather conditions such as a very cold or humid environment. If the wood is very old and the moisture content is very low, that would also prevent the Boracare from absorbing as quickly or easily. If you applied the Boracare to raw wood surfaces, then it should eventually dry. It is common to continue to see some beetle activity after Boracare application since the Boracare cannot completely prevent dormant beetles from emerging. If you still have concerns about the texture after several days, you can also give Nisus (the manufacturer) a call for assistance at 800-264-0870.
You want the siding to be dry when you are applying Boracare per the label. It needs to be able to soak in to the dry wood.
Unfortunately, Boracare is not labeled to be used as a perimeter treatment on concrete. It is lableled to be used on cellulosic materials including wood, plywood, particle board, oriented strand board, cardboard, and wood composite structural componets only.
You could sand wood that has been treated with BORACARE as long as it is completely dry.
