It's always annoying to be sitting calmly on your patio and look down at your feet to see ants marching their way across the surface. While there is no surefire method for keeping ants away from your walkway or patio pavers, there are things you can do to at least reduce the likelihood of an ant infestation.

The best defense you have is to make sure that you properly installed compacted layers of gravel and sand prior to putting down your pavers. Putting in pavers directly on dirt simply invites ants to do their worst. However, another important step you can take to keep ants out is to add a jointing sand as a last line of defense. Doing so can significantly reduce the chance of ants making a home among your pavers.

What You Will Need

  • Jointing Sand
  • Push Broom
  • Tamper (You Can Rent This at a Tool Rental Store)
  • Leaf Blower
  • Garden Hose

Step 1. Choose a jointing sand that is appropriate to the color of your pavers. While most manufacturers produce a basic gray or tan, other color variations are becoming more popular.

Step 2. Before you start this project, check your local weather to be sure that no precipitation is expected for the next 24 hours. Because jointing sand is water activated, cleaning it off damp pavers is extremely difficult. Wait for a dry day to save yourself a headache.

Step 3. Pour the sand out across the surface of the pavers. Put enough that when you sweep across the pavers the jointing sand will be able to fall into and fill up the joints.

Step 4. Use a push broom to start sweeping the sand into the joints. Make sure that every joint is filled completely to the top.

Step 5. Compact the jointing sand and pavers with a tamper to force the sand into the joints.

Step 6. Repeat steps 3-5 3 more times, making sure that every single crack between the pavers is filled. The sand has to be very tightly packed and virtually solid if it's going to form a barrier against ants.

Step 7. Use a leaf blower or a push broom to clean all excess sand from the pavers. This is essential if the final result is going to look professional.

Step 8. Starting at one end of your walkway or patio and working your way to the other end, spray a light mist of water across the joints and pavers with a garden hose. This will clean away any remaining particles or dust on the pavers, but it will also activate the jointing sand.

Step 9. Let the sand sit and cure for approximately 15 minutes. Then mist it one more time. Finally, allow the surface to finish curing for 24 hours before allowing anyone to walk across it.
