Repairing Termite Barrier After Planting Near Foundation

Planting within 12 inches of the foundation risks breaking the termiticide barrier. If you dug farther out, the barrier is likely intact. If closer—or uncertain—here's how to restore it yourself.

DIY Barrier Repair

1. Choose product. Homeowner insecticides with cypermethrin or cyfluthrin (e.g., Tempo, Cy-Kick, Ortho Home Defense Max).
2. Mix 5 gallons at label rate for trench treatment.
3. Trench or rod alongside foundation; pour solution slowly for deep penetration.
4. Treat deck piers and stair stringers the same way.

Critical Steps

• Read the entire label before buying and applying.
• Call your county Extension office (404-897-6261) for product confirmation.
• Wear chemical-resistant gloves and boots.
• Keep pets and children out until dry.

When to Call a Pro

• Active termite infestation (mud tubes, swarmers, damaged wood).
• Slab construction with no access to soil beside foundation.
• You're uncomfortable handling pesticides.

A continuous chemical barrier is your home's best termite defense. Don't leave a gap.
