For furniture your options are limited for treatment. If the wood is in its all natural raw state without any stains or finishes on it you can use a product like Boracare. Boracare will absorb all the way into the wood and eliminate Wood Destroying Fungus, termites and other wood-destroying insects that is effecting it and last for the life of the wood. It does not stain the wood or leave behind any visible residue, but becomes one with the wood and any insect that ingests it dies.
If the furniture has a finish on it, you would either have to drill holes throughout it and inject something like the Boracare or a foam, or the option most go with, hire a
Bora-Care should only be applied to raw wood. It will not penetrate through any wood that has been pre-treated. Polyurethane is equivalent to applying paint, so the best process would indeed to be strip the finish and apply Boracare as this is the only product that will penetrate through the wood and eliminate the existing infestation and prevent future infestations.
You could use a product called Boracare on the barrels but you would be required to seal the inside of the wine barrel after application. The red/white wine stain will not affect the application, only if it were stained with an actual wood stain or sealant.
Bora-Care will penetrate through the wood and kill any insect eating the wood no matter where they are in the wood. However, it can only be applied to raw wood so you would need to apply it to the side that is not painted. It cannot be applied to wood that is painted, stained, or sealed. If your wood is painted, stained, or sealed, then you will need to drill holes and inject Bora-Care or sand the finish off of the wood, treat with Bora-Care, and then refinish the wood
Yes, Bora-Care can be applied either by spraying or painting with a brush onto the unpainted/raw wood surface.
Bora-Care is meant to be applied on all surfaces of raw, unfinished wood so it penetrates all the way to the center of the wood, and will last the lifetime of the wood.
One gallon of Bora-Care will treat approximately 100 lineal feet of 2 x 4 stud wall. You would want to make sure the product has completety dried before restacking. This can typically take up to 48 hours
Boracare should only be applied directly to wood. We would recommend using something like Termidor Foam in the wall voids. This product will be injected at the studs of the wall. Termidor Foam is a non-repellent so the termites do not know they are coming in contact with it. You can drill holes in the stud every 10-12 inches apart. This product has a residual of 3 months.
Bora-Care is a very safe product and it is considered a green product as well. Typically, it takes about an hour for the surface of the wood to dry. After application has dried completely, it should be perfectly fine for children and pets to re-enter the house. Please read the BoraCare product label for complete usage instructions. Boracare does have to be applied to raw, untreated, unpainted wood.
