North Tustin sits in the hillside foothills above incorporated Tustin — geographically and architecturally distinct from the flatland tract neighborhoods of Old Town Tustin and Tustin Ranch to the south, which were developed primarily in the 1950s and 1960s as standard stucco-dominant construction with minimal above-grade wood exposure. The Cowan Heights and Lemon Heights areas that define much of North Tustin represent 1960s through 1980s custom hillside development, where varied architectural wood elements — exposed rafter tails, deck framing, wood-wrapped structural columns, custom fascia — give drywood termites significantly more entry opportunities than typical flatland construction of the same era. At 40 to 60 years old, that custom exterior wood has accumulated the weathering exposure that makes North Tustin one of the more consistently active hillside communities we inspect in central Orange County, and hillside drainage patterns on canyon-facing lots concentrate soil moisture near downslope foundation perimeters in ways that support subterranean activity as well.

Termite Risk in North Tustin
North Tustin 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 North Tustin and what to look for.
Warm Climate Year-Round
North Tustin'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
North Tustin features 1960s–1980s custom hillside development, with custom infill continuing through the 2000s. 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 North Tustin maintain the soil moisture that subterranean termite colonies need. Regular irrigation near foundation perimeters is a common risk factor.
Inspector Note — North Tustin
“North Tustin is one of those areas where I can't assume a standard layout — the hillside lot grades mean every property has a different structural footprint depending on how the lot was cut and what era the custom work was done. I always pay close attention to the canyon-facing foundation perimeter for subterranean evidence and prioritize the deck ledger boards, exposed rafter tails, and any wood-wrapped columns, because those are the architectural elements that accumulate coastal-adjacent weathering exposure fastest on these Cowan Heights and Lemon Heights properties.”
Signs of Termites in Your North Tustin Home
Termites rarely announce themselves. These are the warning signs North Tustin 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.
Termite Treatments Available in North Tustin
We offer every proven treatment method. After a free inspection, our licensed inspector recommends the right approach for your specific infestation and home type.
Tent Fumigation
The most thorough drywood termite treatment. The entire structure is tented and fumigated with Vikane gas, eliminating all drywood termites throughout the home. Required for severe or whole-house infestations.
Tent fumigation details →Orange Oil Treatment
A no-tent alternative using d-limonene (orange oil) injected directly into termite galleries. Effective for localized drywood infestations. No need to leave home. Eco-friendly and low-odor.
Orange oil treatment details →Heat Treatment
The structure or specific areas are heated to 135–150°F, killing all termites and eggs without chemicals. Effective for drywood termites and can treat the whole structure without tenting.
Heat treatment details →Termidor / Liquid Treatment
A perimeter soil treatment using Termidor (fipronil) that creates a protective zone around the foundation. Highly effective for subterranean termites. Long-lasting and transfers through the colony.
Termidor liquid barrier details →We offer 6 treatment methods in total. View all treatment options

Frequently Asked Questions — North Tustin Termite Control
What does "unincorporated" mean for North Tustin homeowners?
North Tustin is an unincorporated community in Orange County — it falls under county jurisdiction rather than being governed by its own city. Unlike incorporated Tustin to the south, North Tustin has no city council or municipal services separate from county-level governance. For homeowners, this primarily means permitting and code enforcement go through Orange County rather than a city. For termite inspection and treatment purposes, the distinction doesn't affect scheduling, licensing requirements, or service — we serve North Tustin directly as part of our Orange County service area, the same way we serve incorporated cities throughout the county.
Why is North Tustin sometimes confused with the city of Tustin?
Mail to North Tustin addresses typically lists the city as "Tustin" or "Orange" depending on specific location, even though North Tustin is a distinct unincorporated community outside both city limits. The Cowan Heights and Lemon Heights areas, which make up much of what residents identify as North Tustin, share the 92705 ZIP code with adjacent incorporated Tustin areas — which contributes to the confusion in mailing addresses and informal references. Residents of Cowan Heights and Lemon Heights consistently identify with those community names rather than the city name that appears in their address, and the termite pressure profile of these hillside communities is meaningfully different from incorporated Tustin's flatland neighborhoods.
How does inspection access differ for North Tustin hillside properties compared to flatland Tustin?
Hillside properties in Cowan Heights and Lemon Heights have variable lot grades that create structural conditions not present in Tustin's flatland tract homes — the same property can have significant crawlspace depth on the canyon-facing side while being nearly slab-level on the uphill side, and custom construction means every home has a different substructure and roofline. Exterior inspection also requires more time on hillside lots with elevation changes between the street-facing and canyon-facing aspects. Our inspectors allow adequate time for North Tustin hillside properties and come prepared with the right access equipment. All hillside inspections in North Tustin are included in our standard free inspection with no surcharge.
What termite issues do you see most often in North Tustin's 1960s–1980s custom homes?
Custom construction from this era predates the borate framing treatments that became standard after 2000, so structural framing hasn't received the built-in chemical protection of newer homes. At 40 to 60 years old, exterior wood elements on North Tustin custom homes have accumulated significant weathering exposure — and the architectural features common to hillside construction of this period, including deck ledger boards, exposed rafter tails, wood-wrapped columns, and custom fascia treatments, are consistently the highest-activity areas we find on North Tustin inspections. Homes that include wood decks on the canyon-facing side of the property carry particular risk because that exposure combines age, wood-to-air surface area, and hillside drainage moisture at the same location.
