Recently I posted about using vinegar and chalk to deter ants, but what happens with more aggressive ants who don’t seem to take the hint? A good way to rid your house of ants is to use borax and sugar. In a bowl mix 1 part borax to 3 parts sugar and dissolve fully in water. Soak cotton balls with the solution. Place the borax and sugar soaked cotton ball in the lid of a two-liter or 20 oz. soda in the area where you have seen the ants. Allow the ants to come to the cotton ball and feed. Resist the urge to kill them there. You want the ants to take the solution back to their home. Over 1-2 days you should notice that the ants stop coming. If they re-appear, simply repeat putting the cotton ball out. After 1-2 treatments the ants should be gone.
Extra solution can be stored in a peanut butter jar or other recycled container. Mark it well so people know it is not for eating. Because you are using borax, be sure to store the solution and place the cotton balls away from where kids can get into them.
