Application Method

Treat soil beneath concrete slabs by drilling through slab and injecting termiticide into sub-slab void and soil. Drill 1/2 inch holes through slab at 12-18 inch intervals along interior and exterior of foundation walls, around plumbing penetrations, and across expansion joints. Insert rod or injection tip through holes to soil beneath slab. Inject 1-4 gallons of diluted termiticide per hole depending on soil type and conditions per product label. Creates chemical barrier in soil preventing termite entry through slab cracks. Critical for post-construction termite treatment of slab-on-grade homes. Patch holes after treatment with concrete patch or epoxy.

Timing

Apply when subterranean termites detected entering through slab or when installing preventive barrier.

Frequency

One-time application provides 5-10 years protection depending on product. Annual inspection for warranty. Retreat if termites breach barrier.

Preparation Required

Locate and mark all utilities and plumbing. Create treatment diagram showing drill hole locations. Calculate volume needed based on square footage and soil type. Have concrete patch ready.

Follow-up Required

Patch all drill holes flush with floor. Clean up equipment. Provide customer with treatment diagram and warranty information. Schedule annual inspection.

Safety Precautions

  • Requires licensed pest management professional with termite certification
  • Do not contaminate water sources or utilities
  • Drill carefully - know location of all utilities, plumbing, electrical
  • Avoid over-application that causes puddling or runoff
  • Ensure adequate ventilation if treating interior
