Application Method

Apply borate to existing wood structures to eliminate active wood-destroying organisms and provide long-term protection. Drill small holes into infested wood and inject borate foam or solution under pressure to penetrate deeply. For wall voids: drill through drywall or exterior siding and inject borate foam that expands to contact all framing members. For accessible wood: apply borate solution via spray or brush ensuring saturation. Foam formulations expand to fill voids and treat inaccessible wood. Borates kill insects slowly through ingestion and provide lasting protection. Effective for termites, powderpost beetles, and carpenter ants. Works on active infestations but slower than conventional insecticides.

Timing

Apply when wood-destroying organisms detected in accessible locations.

Frequency

One-time application provides long-term protection if borates remain in wood. Inspect annually. Retreat if activity recurs.

Preparation Required

Identify extent of infestation. Plan drilling pattern to ensure coverage. Have borate foam equipment ready. Mix product per label. Coordinate customer expectations - slower kill than conventional treatments.

Follow-up Required

Seal all drill holes. Document treated areas. Monitor for continued activity - borate takes time to work. Schedule follow-up inspection in 60-90 days. Explain protection limited to treated wood.

Safety Precautions

  • Requires licensed pest management professional
  • Drill carefully to avoid utilities and excessive structural damage
  • Wear appropriate PPE
  • Do not over-apply foam causing pressure damage
  • Seal holes after treatment
