Since termites do not usually come within 2-3 inches of the top soil, spraying the top surface of the ground with a termicide such as Termidor SC will not have any effect on Subterranean Termites. Doing a barrier soil treatment around the perimeter of home with Termidor SC will give you a 10 year barrier protection against termites. In the areas where there is dirt, dig a 6x6 inch trench pouring 4 gallons of mixed solution every 10 lineal feet (.8 fl oz per gallon of water) For your garage, porch, patios, or other contiguous slabs against the home where you cannot trench, you will drill holes to ensure the termiticide reaches the soil underneath the concrete. Using a hammer drill with a 1/2" x 18" drill bit, drill holes through the concrete about 2 to 3 inches away from the wall or foundation, and about every 10"-12" apart, only on the seam where the concrete is against the foundation. The deeper the better. Once the holes are drilled, you fill at the same rate you did the trench, 4 gallons per 10 feet. This works out to be a little less than half a gallon per hole. 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 Home Depot or you can use our Trebor plugs that will close the hole with no concrete mess.

Yes, Termidor 80 WG can be used as a foam. However, Termidor 80 WG is a restricted use product. It can only be purchased by a licensed pest control operator. You will use a Poly Foamer sprayer and ProFoam Foaming Concentrate. We would recommend using Termidor SC. Termidor SC should not be used indoors unless there is an active infestation and you know exactly where it is. You would treat the area directly.
Boracare can be used when treating the remainder of structural wood in a 5:1 solution. Concentrate application in areas susceptible to attack, to include all sills, plates, floor joists, piers, girders and subfloors. Treat all exterior wood including siding, facias, soffits, eaves, roofing, porches, decks and railing. If Boracare is the sole preventative treatment for subterranean termites, a 1:1 solution must be used.
For Termidor SC to work on Drywood termites, you have to drill directly into the piece of wood the termites are in and inject Termidor into the wood. Termidor does not penetrate into wood, so you have to inject it into the center. It has to touch the termites to work, but the benefit is that it only has to contact a few termites, and then they can pass it on to the rest of the colony.
For Drywood termite treatments on wood, we recommend applying a product called Bora-Care. This product is applied to raw wood and penetrates further than any other product.
Termidor SC is really designed to be used outdoors. Boracare would be best. The interior wood pieces that are exposed will have to be stripped prior to the application if they are painted or stained. The manufacturer has told us that Boracare is not corrosive and it should not harm the interior of the fiberglass that touches the wood.
