Preparing for a wood-destroying insect inspection means making key structural areas accessible for visual and probing examination—crawl spaces, attics, basements, exterior foundations, porches, and any exposed wood-to-soil contacts—and assembling records of prior damage, treatments, and seller disclosures. Inspectors need clear access, good lighting, and unlocked entry points to thoroughly check for signs such as mud…

Professional termite treatments typically provide protection that ranges from about 5 to 10 years for soil-applied chemical barriers, while baiting systems can deliver effective control indefinitely if stations are regularly inspected and maintained; localized wood treatments or structural fumigation eliminate active colonies but do not guarantee against future re-infestation. Longevity depends on the treatment chemistry…

Several wood‑destroying insects are common in Washington state, notably subterranean termites (Reticulitermes spp.), dampwood termites (Zootermopsis spp.), carpenter ants (Camponotus spp.), carpenter bees (Xylocopa spp.), and a range of wood‑boring beetles such as powderpost beetles (Lyctinae) and deathwatch/old‑house borers (Ptinidae/Cerambycidae). These organisms either consume cellulose, bore galleries through structural members, or excavate wood for nesting,…

Late summer is a peak period for termite swarming and colony expansion because warm daytime temperatures combined with higher nighttime humidity and mature colony cycles trigger the emergence of winged reproductives (alates) and the establishment of new colonies. In the Pacific Northwest, the region’s mild maritime climate, abundant coniferous and deciduous forests, and frequent damp…

Termite damage is typically internal, producing hollowed galleries that follow the wood grain and—depending on species—may be accompanied by mud tubes or discarded winged reproductives, whereas carpenter ant damage consists of excavated nesting galleries and visible piles of frass (sawdust-like debris) pushed out from the nest. Termite activity often leaves thin partitions and intact outer…

A summer termite swarm is most often indicated by the sudden appearance of winged reproductive termites (alates) near lights or windows, discarded translucent wings clustered on sills or floors, and swarms of tiny, ant‑like insects emerging from wood, crawlspaces, or soil vents. Other common warning signs include mud tubes or soil-packed galleries along foundations (typical…

Yes — drones are now used for termite inspections, primarily as tools for aerial visual and thermal assessment of a building’s exterior and surrounding vegetation. Equipped with high-resolution cameras and, in some cases, infrared or multispectral sensors, drones can quickly document rooflines, eaves, chimneys, decks, tree stumps and other hard-to-reach areas for signs of moisture…

Termites beneath a concrete slab foundation are typically treated using trenching and liquid termiticides, sub-slab injection through drilled ports, and/or strategically placed baiting systems designed to establish a treated barrier, eliminate foraging workers, and disrupt or eradicate the underlying colony. Treatments focus on re-establishing a chemical or biological zone between soil and structure or directly…

Soil treatment for termites is not a 100% guarantee against infestation or recurrence; when properly selected and applied against subterranean termite species it can create an effective chemical or bait barrier that greatly reduces the likelihood of colony access to a structure. Effectiveness depends on the target species (subterranean termites respond to soil treatments; dampwood…
