Termidor SC cannot be applied on the grass in the lawn for treating any insects including fire ants. It is labeled for applications up against the structure for other ant species and crawling insects as well as in the soil for termite applications. It is not labeled for treating fire ants. We do carry products that can be applied for control of fire ants. Please take a few moments to review our article on How to Get Rid of Fire Ants for more details.
If you are doing a perimeter treatment and there is a basement below grade, then the recommended treatment would involve rodding in addition to the standard 6 in x 6 in trench. A professional company would use a long rod attached to a truck spray rig to inject more termiticide every 12 inches to a depth of at least 4 feet. Since a homeowner does not have those tools, you could use a hollow rod or pipe, or a long drill bit (18-24 inches) to help create space to force more termiticide into the ground, ideally at least what you would use for regular treatment, which averages about ½ gallon of solution every 12 inches.
When apply Termidor SC as a perimeter spray, apply at a rate of 1.5 gallons of solution per 1,000 square feet, using 0.8 ounces of concentrate per gallon of water. You should spray to evenly cover with a low-pressure coarse spray, so you do not need to drench the areas you are treating. Termidor SC should be used in a pressurized sprayer, not in any type of fogging or misting machine. For general perimeter treatments with Termidor SC, see the last two pages of the product label.
Cy-Kick CS is a great product, but Termidor SC is the preferred product for your situation. Termidor SC is a non-repellent insecticide that also has a transfer effect, this means that the ants will not know that Termidor SC has been applied, and therefore cannot avoid the treated area and as they come into contact with other ants they will spread the insecticide and wipe out the colony. Termidor SC can also be used for drywood termites. It is important to remember that you must apply the product into the spaces that these termites will actually come into contact with it. That could mean that you would need to drill into the wood or possibly even foam the product into the space.We have never had a complaint about the smell of Termidor SC and the MSDS says that it is odorless.
Termidor SC is labeled for all types of termites. How you use it is determined by the species of termites you are dealing with. If you have 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 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.
