It depends on the situation in my opinion. More isn't always better. Better is better. If you are treating an infestation in a wall or area that is severe then a .12% solution may be called for. If the ground in one area of your perimeter treatment isnt taking the water drench well then the .12% mixture again might be better. If there is an area on a slab that proves to be impossible to drill your holes 12" apart and you must go a bit wider in that spot then the .12% mixture may be better.
In most cases however the standard .06% mixture will likely work best in the end. Remember how termidor works and this will make sense. The termites that come in contact with the termidor need to live long enough to make contact with other termites in the colony to start the domino effect. The termites themselves are part of the termidor delivery system in that the termites that contact termidor take it back to the colony and pass it on to other termites. If they die too quickly after contact with termidor it will limit effectiveness.
I'm not a pest control specialist but I did stay at a holiday in express last night. Ron may chime in later and give better advice. As I said though, with insecticides/termiticides more isnt always better. Better is better.

Great answer. Basically, Termidor - .6 % is used as a normal dilution in normal situations. The more water the better the penetration, if the soil will allow it. Water is the carrier.
.12% is used in areas where the soil will not absorb the water, such as in hard packed clay, caliche, etc.
For most practical purposes, .6% is best. Double strength or .12% can also be obtained by using Termidor HE (High Efficiency). Termidor HE contains added surfactants to help the penetration of Fipronyl since less water also means less penetration into the soil.
As far as treatments go, the entire perimeter should be trenched and treated, and then if the termites are indoors, at the very least a spot treatment made to the area using Termidor Foam (inside wall voids).
