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…

Termite baiting systems work by placing cellulose-based interceptors in the ground or near structures to attract foraging termites, which consume a bait matrix containing a slow-acting insecticide or insect growth regulator and then transfer that active ingredient through trophallaxis and grooming to other colony members, ultimately suppressing or eliminating the colony. Stations are monitored periodically…

Geographic factors — including local climate, soil moisture and composition, elevation, vegetation, and the distribution of termite species — directly determine where termites are most likely to establish colonies and therefore shape which inspection priorities, prevention measures, and treatment methods will be most effective. Temperature and moisture regimes influence termite life cycles and activity windows;…

Season and climate affect termite prevention because temperature and moisture directly control termite life cycles, foraging behavior, and the durability and movement of treatment materials: warmer, wetter conditions stimulate swarming and colony growth, elevated humidity and persistent dampness promote wood decay and nesting, and seasonal soil moisture alters how far and how long liquid barriers…

Diatomaceous earth (DE) can kill individual termites by abrading their waxy exoskeleton and causing desiccation after direct, prolonged contact, but it is not a reliable method for eliminating established termite colonies or treating hidden infestations. Its mode of action is physical rather than chemical, so DE must remain dry and be applied where termites actually…

Homes in the Pacific Northwest should be inspected for wood‑destroying insects at least once a year, with properties that have elevated moisture exposure, wooded sites, prior infestations, or recent renovations often requiring more frequent checks (every 3–6 months). This baseline frequency reflects the region’s climate and pest ecology: cool, wet winters and persistent humidity create…

A spider problem should be handled by a professional when infestation levels are large or spreading, when a venomous species is confirmed or suspected, when household members have been bitten, or when repeated attempts at DIY control fail to stop ongoing activity. Professional assessment is warranted not only to identify species and bite risk accurately…
