Pavement ants can cause damage to brick patios by building their nests under the pavers. To kill pavement ants you can create a mixture of 1 cup boric acid to 1/2 cup sugar. Use the mixture on areas you see noticeable amounts of ants in a sparing manner. Save the remaining mixture for treatment later.
