Fire Ant Remedy – sprinkle a packet of aspartame (Equal or Nutra Sweet) on the mound. Ants will be gone the next day. Anyone eating or drinking anything containing this stuff is nuts!
Ants, including fire ants, are actually beneficial and I do not recommend killing anything that can naturally do the job some corporations want you to believe only nasty chemicals can do.
Regarding aspartame, you don’t suppose that they are profiting off this poison, then profiting off the health problems that it creates do you? Nah.
