Both Termidor SC (fipronil for termites) and Bora-Care will work, but Bora-Care is typically the better one to use for this situation. Termidor SC is not a wood treatment product, so for it to work you have to drill holes EXACTLY where the termites are and it has to touch the termites to work. If you miss where they are, it will not work. Also, Termidor SC does not really have any residual in the wood, so after you treat inside the wood with Termidor SC and it dries, that wood is exposed for future termite and beetle infestations.

Bora-Care is usually the preferred choice if most of the wood is exposed and it is raw wood you are treating, meaning it is not painted, stained, or sealed, it is just normal wood. Bora-Care is made only for wood, and you do not have to know exactly where the termites are for it to work which is a plus. Bora-Care is sprayed evenly over all exposed surfaces of the wood and actually penetrates through the entire piece of wood. When the termites in the wood try to consume the wood after it has been treated, they ingest the Bora-Care with the wood and die. No matter where they are in the wood the Bora-Care will find them as long as you treated the exposed wood that you can see. The other main benefit is that Bora-Care stays in the wood forever, so you will not have to worry about termites or beetles infesting the wood that you treated ever again.

We recommend that you treat the inside and the outside of the home with one of our Roach Control Kits. They include an insecticide, an insect growth regulator (IGR) and a roach bait gel. Termidor SC can be applied only on the outside of the home once every six months (1 ft up and 1 ft out directly around the structure). Below are some great articles with information on the treatment for roaches that you might find extremely helpful. Please read the product labels for each product for specific application instructions. If you need additional advice, please contact us at 866.581.7378.

Termidor SC when applied to wood would only last about 90 days and would not be used as pre-treatment for wood.
Bora-Care is usually the preferred choice for pre-treating wood that is exposed and it is raw wood you are treating, meaning it is not painted, stained, or sealed, it is just normal wood. Bora-Care is made only for wood. Bora-Care is sprayed evenly over all exposed surfaces of the wood and actually penetrates through the entire piece of wood. For frame up, you would apply to the bottom 2 feet of wood.

You will need to determine what kind of termite you have for us to direct you on the best treatment method.

If you have subterranean termites in your home, we recommend doing the liquid treatment as outlined in the "How To Do A Termite Treatment" article and then inside the home where you know you have the termites you will treat them directly by injecting the Termidor into the wall where the termites actively are or cutting a hole into the wall and spraying on the wood or however you can get the product to the termites. It only needs to touch a few termites to work. If you do not know where the termites are actively infesting we do have a great article here on how to do your own inspection.
