Pavement ants will nest under buildings for warmth during the winter and enter through cracks in the foundation or by following utility conduits upward. Trails of these ants found on upper floors should be followed down to ground level to find where they may be nesting under or outside the building. Carpet edges may need to be pulled back to see where the ants are entering. Nests can be treated with a liquid residual insecticide, either applied under slabs with a crack and crevice injection tip or as a drench to nests near slabs outdoors.
Check out our Ant Biology & Management ProTraining course:
Ants consistently rank as a top pest in the structural pest management industry. After completing this course, you should be able to determine how certain aspects of ant biology affect their management, identify the more commonly encountered pest ant species (depending on region), understand the importance of inspection, and recognize when the application of baits and non-repellent or repellent products are appropriate.
