Application Method
Apply termiticide foam into wall voids, block voids, and other inaccessible areas where termites are active. Foam expands to fill void spaces carrying termiticide throughout area. Drill small access holes, insert foam application tip, and inject foam until void is filled (foam will emerge from other cracks or holes). Foam formulations designed to expand 30-60 times original volume, transferring termiticide throughout galleries and treated wood. Particularly effective for drywood termites in localized infestations, subterranean termites in walls, and treating slab gaps and block voids. Non-repellent termiticides (fipronil, imidacloprid) allow termites to contact foam and transfer to colony. Foam reaches areas inaccessible to liquid treatments.
Timing
Apply when termite activity detected in voids. Can be used any time year-round.
Frequency
One-time application provides control if nest treated. Monitor quarterly and retreat if activity recurs.
Preparation Required
Identify void areas with termite activity. Drill access holes in strategic locations. Have foam equipment cleaned and ready. Mix termiticide to proper dilution for foam application.
Follow-up Required
Seal drill holes. Monitor for continued termite activity. Conduct follow-up inspection in 30-60 days. Document treated areas for warranty purposes.
Safety Precautions
- Requires licensed pest management professional with termite certification
- Drill carefully to avoid electrical wiring and plumbing
- Do not over-apply - foam expands significantly
- Use appropriate PPE during mixing and application
- Follow label directions for dilution and application rate
