There are countless tips and tricks for getting rid of unwanted ants, some of which are more effective than others. One technique is a simple application of cornmeal. However, cornmeal by itself is more likely to make the ants relocate rather than actually kill them. For this reason, boric acid should be added to the cornmeal. Boric acid is lethal to ants but will not harm humans or pets in small doses.
Mix 1 part boric acid to 10 parts cornmeal in a mixing bowl. For example, add 1 cup of boric acid to 10 cups of cornmeal.
Stir the boric acid and cornmeal together with your hands to thoroughly mix them together.
Sprinkle the cornmeal and boric acid mixture on top and around the anthills. Use just enough so there is a thin layer on the ground. The ants will eat the cornmeal, which will ultimately kill them due to the boric acid. If you have several anthills, apply the mixture on all of them.
Check the anthills two days later. If the ants are still active, apply more of the cornmeal mixture.
