Most of the country worries about subterranean termites that come up from the soil. In Murrieta and across Southern California, drywood termites are the primary threat—they live entirely inside wood, need no soil contact, and can infest any wooden structure from the roof down. Treatment strategies that work in the Southeast or Midwest often fail here.

While subterranean termites exist in Riverside County, drywood termites (Incisitermes minor) are the dominant structural pest in Murrieta and the greater Inland Empire.
The difference matters enormously for treatment. Subterranean termites are treated with soil barriers and baiting systems around foundations. Drywood termites don't touch soil. They fly in as winged "alates" during swarming season, bore directly into exposed wood, seal themselves inside, and build colonies entirely within the wood they eat. They can infest roof framing, window frames, door frames, furniture, and any untreated wood—regardless of its distance from the ground.
Murrieta's climate is ideal for drywood termites. Low humidity and warm temperatures year-round create the dry conditions drywood termites prefer. The wood moisture content in Inland Empire homes—typically 8-12%—is exactly within drywood termite requirements. Homes at every price point and in every neighborhood are vulnerable.
Drywood termite swarms in Murrieta typically occur September through November, triggered by warm days followed by temperature drops. Swarmers are attracted to lights and are often found around windows and light fixtures. Finding winged termites or their discarded wings inside your home means an active colony is already established in your structure—they swarmed from within, not from outside.
Murrieta's #1 termite species. Colonies of 1,000-3,000 individuals living entirely inside wood. They produce distinctive hexagonal fecal pellets (frass) that they kick out of "kick holes"—small openings in infested wood. Finding tiny piles of pellets resembling coarse sand below window sills, door frames, or along baseboards is the classic sign. Multiple colonies can independently infest different areas of the same home.
Present in Murrieta but less damaging than in humid climates. Build colonies in soil and access structures through mud tubes along foundations, inside wall voids, and through cracks in slabs. More common in irrigated areas and properties with poor drainage. The older neighborhoods in central Murrieta with established landscaping see more subterranean termite activity than newer, drier developments.
Large termites that infest wood with high moisture content. In Murrieta's dry climate, they're limited to areas with persistent moisture problems—leaking roofs, failed shower pans, plumbing leaks behind walls, and wood in ground contact. Their presence always indicates a moisture problem that needs to be solved. Less common than drywood species but cause significant localized damage.
Not yet established in Riverside County but spreading across Southern California. These "super termites" build colonies of millions (vs. hundreds of thousands for native subterranean species) and can cause catastrophic structural damage. Monitoring for their arrival is important for long-term home protection in the Inland Empire.
Fumigation remains the only treatment that reaches every drywood termite colony throughout an entire structure. The home is sealed under a tent, and sulfuryl fluoride gas penetrates all wood, killing termites in walls, attics, and areas impossible to access by other methods. In Murrieta, where multiple independent drywood colonies commonly infest different areas of the same home, fumigation provides complete elimination in a single treatment.
The process requires 2-3 days away from home. All food, medications, plants, and pets must be removed. While disruptive, it's the definitive treatment when infestations are widespread or when colonies are in inaccessible locations like roof framing and interior wall framing.
When drywood termite infestations are limited to accessible areas—a single window frame, a section of baseboard, or an exposed beam—localized treatment can be effective. We inject termiticide directly into galleries and infested wood. This approach works when all infested wood can be identified and accessed. It's less disruptive than fumigation but requires confidence that no hidden colonies exist elsewhere in the structure.
For subterranean termite activity, we apply liquid termiticide to soil around foundations, creating a continuous barrier. In Murrieta's dry, well-drained soils, these treatments perform well and maintain efficacy for years. We also identify and address conducive conditions—irrigation hitting foundations, earth-to-wood contact, and moisture accumulation near the structure.
Borate-based wood treatments applied to exposed framing (during construction, renovation, or attic access) create long-lasting protection against both drywood and subterranean termites. For Murrieta homeowners planning remodels or additions, treating new wood before enclosure is one of the most cost-effective termite prevention investments available.
Likely yes. Drywood termite frass consists of tiny hexagonal pellets, about the size of coarse sand grains. They're hard, dry, and vary in color depending on the wood being consumed (often tan, brown, or reddish). The pellets accumulate below "kick holes" where termites expel waste. If you find these piles—especially below window frames, door frames, or along baseboards—you have an active drywood termite colony in the wood above.
It depends on the extent and accessibility of the infestation. If frass is found in one or two accessible locations, localized treatment may suffice. However, drywood termites often have multiple independent colonies throughout a structure—you may see evidence in one area while other colonies remain hidden in walls and attic framing. A thorough inspection determines which approach is appropriate. When in doubt, fumigation provides certainty.
Drywood termites typically swarm September through November in the Inland Empire, usually on warm days (above 80°F) following a period of cooler weather. Subterranean termites swarm in spring, usually after rain events. Finding swarmers or discarded wings indoors means an established colony exists in your structure. Finding them outdoors near your home means colonies are nearby and your home is at risk during future swarming events.
In the Inland Empire, annual termite inspections are advisable for homes over 10 years old. Drywood termites work slowly compared to subterranean species—colonies grow over years, not months. Annual inspections catch infestations early when localized treatment is still an option, potentially avoiding the need for whole-structure fumigation.
Drywood termites work silently inside your walls and roof framing. Professional inspection identifies active colonies before damage becomes severe.
