Application Method
Treat voids between floor and foundation/substructure in homes with raised foundations. Access voids through foundation vents, access panels, or drilled holes. Apply insecticidal dust using extension tubes and dusting equipment to fill voids and coat surfaces. Apply residual liquid spray to accessible areas. Dust formulations preferred for sub-floor voids as they provide extended residual in protected environment. Target application to areas around plumbing penetrations (common pest entry points), along perimeter walls, and around heating ducts. Sub-floor voids often provide protected harborage and travel routes for pests entering from crawl space or foundation into living space above.
Timing
Treat when pest activity indicates sub-floor harborage or as comprehensive exclusion measure.
Frequency
One-time application provides long-term control in dry voids. Quarterly treatment for moisture-prone or high-pressure areas.
Preparation Required
Identify sub-floor void areas and access points. Determine void depth and volume. Have extension tubes and dusting equipment ready. Select appropriate dust formulation.
Follow-up Required
Seal access holes or replace foundation vent screens. Document treated areas. Monitor for pest activity reduction. Dust provides long-term control if kept dry.
Safety Precautions
- Requires licensed pest management professional
- Wear respirator when applying dust
- Ensure voids ventilate to exterior not living space
- Do not over-apply dust
- Seal access points after treatment
- Mark treated areas for future reference
