How Do You Kill Ants Using Vinegar?

To eliminate colonies of ants, pour undiluted white or apple cider vinegar directly into the ant mounds on the property, and use a spray made with equal parts vinegar and water inside the home. Spray the affected areas of the home with the vinegar mixture, and spray along baseboards and near entrances to the home to prevent additional ants from entering. Spray the home several times each week until the ants are gone.
