Liquid Soil Barrier (Termidor)
Stop Subterranean Termites at the Source
Termidor (fipronil) is applied as a continuous liquid barrier in the soil around your foundation. Subterranean termites contact or ingest the product and transfer it to colony members, eliminating entire colonies — not just foragers.

Inspection
Confirm subterranean termite species and entry points.
Trenching
A trench is dug along the foundation, typically 6 inches wide and 6 inches deep.
Drilling
Holes are drilled through concrete slabs at foundation level where necessary.
Application
Termidor is applied at labeled rates to create a continuous treated zone.
Backfilling
Trenches are backfilled and drill holes patched.
Perimeter Verification
We verify the continuous barrier has no gaps around the entire structure.
