Community Tips
Apply ant barrier spray or granules in a continuous 12-inch perimeter band around the foundation's base, focusing on cracks, utility penetrations, and areas where soil contacts siding. Terro Ant Killer Plus ($8-12) creates a zone that eliminates scouts before they establish pheromone trails, preventing colony recruitment to interior spaces.
Reapply barrier treatments every 4-6 weeks or immediately after heavy rain, as water displacement significantly reduces effectiveness -- many homeowners skip this step and incorrectly assume the initial application failed. UV exposure also degrades most active ingredients, making spring reapplication essential even in dry climates.
Granular barriers like Ortho Home Defense Max ($12-16) typically cost 40% less per application than liquid sprays when treating the same perimeter distance, though sprays cover irregular surfaces more effectively around foundation cracks and require less cleanup afterward. ---
