Subterranean Termite Treatment — Quick Facts
Why Subterranean Treatment in Tustin?
Mix of old MCAS housing and newer development.
In Tustin, subterranean termites enter through soil-to-wood contact points, cracks in concrete, and utility penetrations. Termidor soil treatment creates a zone that termites can't detect, pass through, and transfer back to the colony.
All subterranean termite treatment services in Tustin are performed by our CA-licensed inspector (License #PR7791) and come with a written report, warranty documentation, and a free inspection before any treatment is recommended.
Inland valley homes often have subterranean termite activity driven by irrigation systems, lawn watering, and moisture-retaining clay soils. Termidor creates a continuous treatment zone that intercepts foraging termites before they reach wood structural members.
Peak termite swarm season in Tustin: April–May. Don't wait for visible damage — early treatment costs a fraction of structural repairs.
Inspector Note — Tustin
“Old Town Tustin homeowners on El Camino Real often have original brick foundations with wood sill plates sitting directly on masonry — inspect the sill plate-to-masonry interface closely for both drywood and subterranean activity.”
