Termidor SC can be shipped to California but it cannot be used for indoor applications. Since you have drywood termites in the attic, the most recommended product for your situation would be Bora-Care. Bora-Care is applied to raw wood for termite control and it will penetrate the entire piece of wood and erradicate an active infestation as well as preserve it. The great thing about Bora Care is that it is natural, last for the entire life of the wood (never goes away), and dries completely clear. Termidor would not be recommended because it doesn't penetrate wood and injections directly into the affected wood would be neccessary for treatment and it doesn't last very long.
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 SCÂ has soil binding molecules in it that will allow it to bind to any soil regardless of the density. It is not labeled to be used with a foaming agent in the trenching method.Â
Your treatment should not be done within 24 to 48 hours of any rainfall for the best results. Your trench should be 6'' wide, 6'' deep and 10 linear feet along the structure with the Termidor. You can take a look at our site on How to Do a Termite Treatment to give you the proper application instructions for the best results.
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.
No, there is no need to be concerned. As long as your vegetable garden is not directly sprayed with the Termidor SC or so close to the treatment area that runoff or overspray comes in contact with the garden, Termidor SC is safe to use. There is no worry of ants transferring Termidor to any vegetation.
