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.
Termidor SC should not be applied to flowers or shrubs. It is only applied in the soil up against the foundation of the structure for termite control (in a trench, rodded, drilled holes in concrete) or ant control topically (1 ft up and 1 ft out).
No, Regardless of what treatment you are doing Termidor SC can only be mixed at .8 fl oz. per gallon of water. Termidor SC is a non-repellent, if you mix at a stronger strength than labeled you run the risk of taking away its non-repellent properties. Always mix at .8 oz to a gallon.
Termidor SC can be toxic to Millipedes. When applied per label, Termidor will not harm plants. Be sure to keep all children and pets out of the treated area until dried.
While Bifenthrin can show repellent qualities to some insects, it is not considered a "repellent". You can use Bifenthrin based products indoors. It will not pose a threat to your Termidor Treatment outdoors. You do not want to apply these types of products in the same area, as in on top of one another.
