Amdro is the original sprinkle granuals and it is effective. The real issue is that once a mound is dead other tribes are looking to invade and when they find new ground a new queen is born and half of the hive splits and moves to the territory, Just like the Mongols.
Please be sure the mound really has ants in it. Be aware that gopher tortoises, when the create a den, will run under ground pushing dirt. When they can't push it any longer the get under it and push it up. These pushups look, for all the world, like ant mounds. They are not; so don't wast your Amdro.
As for diesel, using that is simply poisoning your property and your water. Diesel will sink through the soil until it finds water and now your wells are put in jeopardy as well as any animal that drinks the water. Don't do it.
