Termidor SC does need to be applied directly to soil. If you have concrete up against the foundation around the home you would need to drive every 10-12 inches through it and inject/spray ½ gallon into every hole as outlined in our Prevention guide here
If concrete such as a carport slab or sidewalk is against the foundation in the area where you need to treat, you will be required to drill through the concrete to apply the termiticide solution to the soil. Using the hammer drill with a 1/2" x 18" concrete drill bit, drill holes every 12" into the concrete along the foundation wall.
You are not only drilling through just the concrete here, but also as deep as you can into the dirt. The deeper the better. Once the holes are drilled, you fill at the same rate you did the trench, 4 gallons per 10 feet. If you drilled the holes 12 inches apart, then you would have 10 holes over 10 feet that you are trying to fill with 4 gallons. This works out to be a little less than half a gallon per hole. To fill these I would recommend using the one gallon sprayer on a "pin stream" setting so you can force the liquid down the hole and not splash it everywhere. You can also use a funnel and pour the termiticide down the holes. It is difficult to get 4 gallons per 10 feet in the holes, so it is important that you use a long drill bit, at least 18" long so you can bore out enough dirt to hold the termiticide. Sometimes the ground is slow to soak up the termiticide you place in the holes. You may need to fill the holes, then go work on something else for an hour, come back and fill them again, go work on something else... 3 to 4 times to get the proper amount down the holes. Once the holes are filled all you need to do is patch them with a concrete patch filler you can buy at a home improvement or hardware store or you can use our Trebor plugs that will close the hole with no concrete mess.
Termidor SC should not be applied through a hose end applicator for application to the lawn and flower beds for ant control. It should only be sprayed a couple of times a year directly up against the foundation of the strucutres on the property (1 ft and 1 ft out). We would recommend using Arilon Insecticide. It can be used around the perimeter of the home and you could expand the band around the perimeter, for example: you can spray 3 feet up on the foundation and 7 feet out. The active can also be transferred from one ant to another and can be used for direct mound treatments if necessary, as well as surfaces commonly used by ants for foraging such as outdoor edges/frames of windows, doors, utility penetrations, roof lines or eaves, and other structural edges may also be treated. In addition to exterior structural elements, outdoor nesting sites such as refuse collection areas, flower/mulch beds, adjacent tree holes, surrounding turf areas, crawl spaces, or other nest/ foraging sites, and foraging trails can be treated.
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.
We also have a great article here about Barrier and Soil Treatments for termites that might be helpful.
You will need to determine what kind of termite you have for us to direct you on the best treatment method. Bora-Care is usually the preferred choice if you are dealing with Drywood Termites and 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.

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.
Termites do not normally attack live, healthy trees so you most likely will not find any products that will work as a ground barrier around the trees. Most people are primarily concerned with protecting the big investment, their home, and Termidor SCwould be the product to use for that. It is only labeled to be used adjacent to the structure though. Please take a moment to read over our article on "How to do a Termite Treatment" for complete details.
