The answer to this question is also in our How To Do A Termite Treatment Article. You will want to use the Termidor product. For your concrete areas against the home, you will need to get the termiticide underneath the concrete against the foundation. To do this you will need a hammer drill with a 1/2" x 18" drill bit. You drill holes throughout the concrete about 3-4 inches away from the wall or foundation, and about every 10"-12" apart. Once the holes are drilled, you fill at the same rate you did the trench, 4 gallons per 10 feet. 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. Once the holes are filled all you need to do is patch them with a concrete patch filler you can buy at Home Depot or you can use our Trebor plugs that will close the hole with no concrete mess.
As for your areas with rock over dirt, again - you need to get the termiticide product down into the soil to be most effective. We recommend digging a 6in x 6in trench to pour the solution into the ground.
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.

When treating a block foundation, you should drill a hole in each void so there would be 2 holes per block. The holes should be no more than 18 inches high. Usually you want to drill on the second row of blocks high from the ground. In addition to drilling the holes, you should also trench and treat the outside foundation wall and the inside foundation wall if you have a crawl space. After drilling the holes, you are supposed to apply 2 gallons of solution per 10 lineal feet into the blocks. For filling trenches and drill holes going vertically into slabs, you should apply 4 gallons per 10 lineal feet. Please let us know if you have any further questions.

How To Perform A Termite Treatment
Termidor SC has a shelf life of 3-5 years if kept in a cool dry place. The "rotten" smell that is coming from the Termidor Sc could be a sign that it has gone bad. If Termidor was been exposed to extreme heat, this could lessen the shelf life.
If the footer is right below the dirt level, within 6 inches, and it comes out 12 inches, then you should make your trench out where the footer ends. In other words, instead of digging a 6 inch trench directly against the structure, you will move the trench away from the house where you can dig down past the footer. You should still treat the soil in between the trench and the house (where the soil sits on top of the footer) by just drenching the soil if you can.
