California-licensed termite inspectors serving Tustin Old Town and all of Orange County. Free whole-structure inspections, honest treatment recommendations, and every method available — from orange oil to tent fumigation.
Tustin Old Town contains some of the oldest residential construction in central Orange County — craftsman bungalows, Victorian-era homes, and Spanish colonial revival structures built between the 1880s and 1940s with original wood framing that has had 80–140 years of exposure. The city's historic district designation protects the architectural character of these properties, but it also means original wood elements — porch decking, fascia, window frames, and structural framing — have often never been treated. Drywood termite pressure in this neighborhood significantly exceeds the city of Tustin's overall medium rating and matches the profile of the oldest Long Beach historic districts.

Termite Risk in Tustin Old Town
Tustin Old Town homes face elevated termite pressure due to the area's construction history, local climate, and housing stock characteristics. Our inspectors are familiar with the specific conditions in Tustin Old Town and what to look for.
Warm Climate Year-Round
Tustin Old Town's mild temperatures allow termite colonies to remain active throughout the year — unlike colder climates where activity slows in winter. There is no "off season" for termites in Southern California.
Aging Wood Structures
Tustin Old Town features 1880s–1940s craftsman bungalows, victorian-era homes, and spanish colonial revival; some 1950s–1970s infill. Older wood framing, fascia, and eaves are more susceptible to drywood termite infestation, especially if paint or sealant has deteriorated.
Moisture and Humidity
Moisture from coastal air, irrigation, and local drainage patterns creates ideal conditions for subterranean termites, which require soil moisture to thrive. Foundation areas, crawlspaces, and soil-to-wood contact points are especially vulnerable.
Established Landscaping
Mature trees, irrigated gardens, and established landscaping in older communities like Tustin Old Town maintain the soil moisture that subterranean termite colonies need. Regular irrigation near foundation perimeters is a common risk factor.
Inspector Note — Tustin Old Town
“Old Town Tustin is the oldest housing stock I regularly inspect in central OC. The craftsman bungalows on and near El Camino Real have original framing from the 1910s and 1920s that has never been treated in many cases — drywood colonies in these structures have had decades or more to establish without any interruption. The brick foundation sill plate interface is the first place I check: original sill plates sitting directly on masonry are a dual entry point for both drywood and subterranean activity simultaneously. For historic district properties, treatment options include targeted spot treatment and orange oil to preserve historic wood where fumigation isn't appropriate for the homeowner's situation.”
Signs of Termites in Your Tustin Old Town Home
Termites rarely announce themselves. These are the warning signs Tustin Old Town homeowners most commonly miss until the damage is already significant.
Frass / Droppings
Small hexagonal pellets that resemble sawdust or coffee grounds appearing below eaves, window frames, or baseboards. This is drywood termite waste and a definitive sign of active infestation.
Kickout Holes
Tiny round holes (about 1mm) in wood surfaces — typically in eaves, fascia, or door frames — where drywood termites push frass out of their galleries.
Hollow-Sounding Wood
Tapping on structural wood that sounds hollow or papery indicates termites have consumed the interior while leaving a thin outer shell. Common in attic beams, window sills, and floor joists.
Mud Tubes
Pencil-width tunnels of mud and debris running along foundation walls, pipes, or exterior surfaces. These are the travel highways of subterranean termites, built to maintain moisture as they move from soil to wood.
Swarmers / Flying Termites
Winged termites (alates) emerging from walls or flying near windows are a strong sign a mature colony is nearby. They shed their wings quickly — discarded wings on windowsills are a common clue.
Blistering Paint
Paint that bubbles, blisters, or peels from the inside out — without an obvious water source — can indicate subterranean termites tunneling through wall framing, introducing moisture as they work.

We offer every proven treatment method. After a free inspection, our licensed inspector recommends the right approach for your specific infestation and home type.

Frequently Asked Questions — Tustin Old Town Termite Control
Why is drywood termite risk in Old Town Tustin higher than the city of Tustin overall?
The city of Tustin spans housing stock from the 1880s through the 2010s, which averages out to a medium risk profile overall. Old Town Tustin is specifically the 1880s–1940s historic core — construction in this range carries critical drywood risk because the wood is 80–140 years old, typically never treated, and has seen multiple decades of swarming seasons with opportunities for new colonies to establish. The newer Tustin Ranch and Tustin Legacy developments bring the city-wide average down, but they're not representative of what we find in Old Town.
What are the specific risks in a historic craftsman or Victorian home in Old Town?
Several: original wood framing, porch decking, eave fascia, and window frames that have never been treated for termites. Brick foundation construction common in this era means wood sill plates sitting directly on masonry — a dual entry point for both drywood (entering from above) and subterranean termites (migrating up through the masonry interface). Original tongue-and-groove subfloor and exposed porch framing are also common drywood habitats. The volume of original wood in a craftsman bungalow from this era means an active infestation may be present in multiple locations simultaneously.
Does historic district designation affect treatment options?
The historic district designation governs exterior architectural changes, not pest control treatments. However, many Old Town Tustin homeowners prefer non-tent options to minimize disruption to original wood elements and historic materials. Orange oil (d-limonene) and targeted spot treatment are effective for accessible infestations and preserve historic wood while eliminating active colonies. For widespread, inaccessible infestation across a historic structure, fumigation remains an option — it doesn't damage the wood itself. Our inspector will lay out which methods apply to your specific findings and let you choose.
How does Old Town Tustin compare to North Tustin in termite risk?
North Tustin is an unincorporated OC community with predominantly 1960s–1980s ranch homes on larger lots — a different vintage and construction type entirely. North Tustin carries high drywood and medium subterranean risk given its age and terrain. Old Town Tustin's 1880s–1940s historic construction is significantly older and carries critical drywood risk that North Tustin's mid-century construction doesn't. The two neighborhoods are distinct in character, age, and risk profile despite being geographically close.
