1. Baking Soda
This is could be the quickest and easiest method on this list for getting rid of ants. Mix equal parts baking soda and powdered sugar. Place the mixture in an ant hangout spot or where they’re entering your house. The sugar will attract them and the baking soda will kill them. Save the remaining sugar to make a cake after the ants are gone.
Borax seems to be the most popular and effective DIY method. Borax is a multi-purpose cleaner that moonlights as an ant assassin. You can find it in the laundry section of your grocery store. However, it does not have an inviting smell, and we can only assume it tastes equally awful. So you’ve gotta dress it up. The Ant Killer Blog recommends this: mixing one part 20 Mule Team Borax with three parts granulated sugar. Pour it into a small sealable container with several pencil-size holes about ½ inch from the top. These are the ants’ entry and exit points. The powder level should reach ½ inch below these holes, allowing you to add enough water to create a “slightly soupy” consistency. Finally, stir in one teaspoon of peanut butter or honey. Cover the container to prevent pets from eating it, and put it where ants will find it but kids will not. Borax is toxic. The ants will take it back to their colony and should be gone within two to fourteen days.
