Suresh from Chennai, India writes
When performing a spot treatment behind a wall it is very important to drill directly into the affected stud and foam into the termite galleries as well as the void on either side of the stud. You will not foam the entire void with Termidor Foam, rather you will drill a hole close to the top of the ceiling/stud on either side of the stud. Once the holes are in place on each side, inject the foam into each hole for 5-10 seconds, allowing the foam to expand but slide down the sides of the studs where they would travel. Foam is preferred because it has the ability to expand and travel deep into the termite galleries, cracks and crevices, and wall void much better, which does provide better coverage than liquids.
