Well I have a 8 step PROVEN METHOD and it is TOTALLY FREE!
1. Fill 2 big pots of hot water, bring to a rolling boil.
2. Go outside with 1 pot of boiling water.
3. Find the ant mound that gets you pi$$ed off.
4. Poke a hole in the mound using a stick.
5. When they start coming out, pour the boiling water down the center of the mound and all around it and saturate the mound!
6. Water seeps into the dirt very quickly, going all the way down to the bottom of the nest as well as all the little tunnels.
7. Go back in a get the 2nd pan of boiling water, go outside, pour into the mound again or find another mound, repeat the process.
8. Pretty cool to go back to the mounds the next day after the dirt has dried and find all the little B#*@&^%ds ALL BOILED TO DEATH and DEAD!!
Problem solved!
