It is completely up to what you prefer, some people are more infatuated with the name brand product Termidor SC but they are the same product and work in the same manner so it is completely left to what you prefer to go with.
Termidor SC is NOT labeled for indoor general pest control. The Termidor SC product label only allows indoor applications to wall voids (behind sheetrock), unfinished attics, unfinished basements, and crawlspaces. Termidor SC could be harmful if used in violation of the product label. We would recommend using Phantom indoors for non repellent ant control.
If that expansion joint is the only area of activity and Termidor SC was used for the initial treatment, most professionals would just treat that area of localized activity. It is possible the termites there came from a colony deep under the soil surface where they would not have come into contact with the existing liquid barrier. You would treat the expansion joint similarly to how you would treat the foundation, using 4 gallons of solution per 10 linear feet, applying evenly into drilled holes. Instead of placing the holes all on one side, however, you would drill them in a zig-zag pattern along the expansion joint. Please let us know if you have further questions.
Termidor SC can be applied to the soil topically (1 ft up and 1 ft out directly up against the foundation) and in a trench for termite control. There should not be any harm done to any grass sprayed.

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.

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.
