High RiskTermite Control in Rowland Heights, CA
California-licensed termite inspectors serving Rowland Heights and all of Los Angeles County. Free whole-structure inspections, honest treatment recommendations, and every method available — from orange oil to tent fumigation.
Rowland Heights' 1970s–1990s tract construction puts most housing stock in a vulnerable age window: old enough for significant weathering and drywood entry point accumulation on exterior wood, but predating the widespread borate framing treatments that became standard in newer construction. The community includes both flatter residential tracts and hillside areas in its upper sections, with aging wood throughout driving consistent drywood pressure. Irrigated residential landscaping and hillside drainage patterns create sustained subterranean termite pressure across the community, particularly at foundation perimeters where aging pressure-treated lumber has degraded over the decades.

Termite Risk in Rowland Heights
Rowland Heights 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 Rowland Heights and what to look for.
Warm Climate Year-Round
Rowland Heights'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
Rowland Heights features 1970s–1990s tract construction with continued residential development through the mid-1990s. 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 Rowland Heights maintain the soil moisture that subterranean termite colonies need. Regular irrigation near foundation perimeters is a common risk factor.
Inspector Note — Rowland Heights
“Rowland Heights is primarily tract construction — the 1970s blocks look different from the 1990s blocks, but it's production-built throughout the flat sections, which makes inspections efficient. In the older 1970s sections, exterior trim and eave wood has had 50 years to accumulate entry points; I go through those attics carefully because drywood activity in original framing is common. The hillside areas in the upper sections change the picture — drainage patterns against foundations are a key subterranean indicator there, and I allocate more time on those properties.”
Signs of Termites in Your Rowland Heights Home
Termites rarely announce themselves. These are the warning signs Rowland Heights 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 Rowland Heights
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.

Frequently Asked Questions — Rowland Heights Termite Control
Rowland Heights is unincorporated — does that affect termite service?
It doesn't affect service at all. Rowland Heights is an unincorporated CDP in Los Angeles County with its own ZIP code, community identity, and active real estate market. We serve all of Rowland Heights as part of our LA County service area — same licensed inspectors, same treatment options, same warranty that apply throughout the county. Real estate agents, escrow companies, and homeowners in Rowland Heights schedule service with us the same way they do in any incorporated LA County city.
What termite issues are typical in Rowland Heights' 1970s–1990s tract homes?
Drywood termites in aging exterior wood — trim, fascia, and window frames — are the consistent finding across the housing stock. Homes from the 1970s have wood that's been weathering for 50-plus years without modern preventive treatments; 1980s homes are in a similar position with 40-plus years of exposure. By this age, entry points have accumulated on most unprotected exterior wood surfaces regardless of maintenance history. Subterranean activity along foundation perimeters is also common in properties with established irrigation — particularly in older homes where original pressure-treated foundation lumber has degraded.
How does Rowland Heights termite pressure compare to neighboring Hacienda Heights?
The profiles are similar — both are unincorporated inland east LA County CDPs with older housing stock and no modern borate framing. Hacienda Heights has a somewhat older construction core (more 1960s–70s) and Rowland Heights has its own hillside areas in its upper sections. Both communities carry high drywood risk from aging exterior wood and high subterranean risk from residential irrigation and hillside drainage patterns. The practical difference is modest: Hacienda Heights' core is somewhat older, but both communities warrant thorough inspection for both species.
Is subterranean or drywood termite pressure more common in Rowland Heights?
Both are significant concerns across the community. Drywood termites are the more consistent finding in exterior wood — trim, fascia, and window frames have accumulated entry points across the aging housing stock. Subterranean pressure is also consistent throughout Rowland Heights: irrigated landscaping maintains the soil moisture conditions subterranean colonies need at foundation perimeters, and hillside areas in the upper sections add drainage-driven concentration that creates additional pressure points. Properties with dense planting adjacent to the foundation or on hillside lots with drainage toward the structure show the highest subterranean risk, but baseline subterranean activity is present broadly across the community.
