The first step in controlling pavement ants is to locate the colony. To do this, watch where the ants are coming from, and once you reach a wall, go to the other side of it to see if you can determine how the ants are getting into your living or work space. Often, minuscule cracks allow these tiny invaders to enter unchecked, so once you’ve discovered how the ants are getting in, use silicone sealer or a similar substance to eliminate the gaps.
Next, look for any other gaps or cracks in exterior walls where pavement ants might be able to enter. Seal any cracks that look like potential entry points, and look for any areas where drainage problems or leaks might exist since these problems can lead to more cracks by undermining the foundation’s supportive structure.
