Termite Risk in Irvine
Irvine's master-planned layout and HOA-maintained landscaping create consistent irrigation patterns that keep soil moisture elevated year-round, driving above-average subterranean termite pressure despite relatively modern construction. Drywood termites are less dominant but still active, particularly in older Irvine Company developments from the 1970s–80s in University Park and Westpark villages.
Warm Climate Year-Round
Irvine'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
Many homes in Irvine were built in the 1950s–1980s. Older wood framing, fascia, and eaves are more susceptible to drywood termite infestation, especially if paint or sealant has deteriorated.
Coastal Humidity
Moisture from coastal air and irrigation creates ideal conditions for subterranean termites, which require soil moisture to thrive. Foundation areas, crawlspaces, and soil-to-wood contact points are especially vulnerable.
Dense Housing
In densely-developed areas like Irvine, termite swarmers from neighboring properties can easily establish new colonies in your home. A neighbor's treatment can even push colonies into adjacent structures.
Inspector Note — Irvine
“HOA common-area irrigation in Irvine neighborhoods often runs within 12 inches of foundations — probe soil moisture near the foundation perimeter before concluding subterranean risk assessment.”
Signs of Termites in Your Irvine Home
Termites rarely announce themselves. These are the warning signs Irvine 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 Irvine
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 130°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.
