Honesty is the best place to start: Spokane is not termite country in the way Florida or Texas is. Cold winters, dry summers and relatively low humidity limit wood-destroying insects across much of Eastern Washington. That said, damp or decaying wood can still draw termites and look-alike pests, and if you find signs in your home, it deserves a proper inspection rather than guesswork.
What is actually found in the Inland Northwest
The termites most often associated with Washington are dampwood termites, which infest very wet, rotting wood such as stumps, fence posts and deteriorated timbers, and subterranean termites, which are more of a west-side and southern concern. In the Spokane area, activity is generally rare and tied to moisture problems. By contrast, carpenter ants are common and are frequently mistaken for termites because both leave damaged wood and both produce winged swarmers. A professional can tell them apart quickly.
Where moisture sets the stage
Spokane's freeze-thaw cycles push water into small cracks. Over decades, that can degrade window sills, porch posts, deck ledgers and fascia boards. In older houses on the South Hill, in Browne's Addition and in Hillyard, crawl spaces and basement sill plates may stay damp where grading slopes toward the house. Bathrooms and kitchens with slow leaks can soften subfloors. Snow piled against siding during winter melts into the wall base. These are the places that attract wood-destroying organisms, whether insects or fungi, and addressing the moisture matters more than anything else.
Clues worth investigating
- Winged insects emerging indoors in spring or early summer. Termite swarmers have two pairs of equal-length wings and a thick waist; ant swarmers have a narrow waist and unequal wings.
- Tunnels in wood with a clean, sandpapered look (carpenter ants) versus mud-lined, rough galleries (termites).
- Frass piles below a slit in a beam or sill.
- Soft, spongy wood that gives way to a screwdriver, which often indicates decay fungi instead.
What an inspection includes
Inspectors examine foundation sills, crawl spaces, attic framing, deck connections and exterior trim. They use a moisture meter, probe suspicious wood and look for the pattern of damage that identifies the culprit. If it is dampwood termites, the fix is usually removing and replacing the wet wood and correcting drainage, with targeted treatment if needed. If it is carpenter ants, treatment involves locating the nest and applying baits or insecticide to the galleries. Fungal rot calls for a carpenter rather than an exterminator, and an honest provider will say so.
Reducing risk in a cold climate
- Keep soil and mulch several inches below siding and wood trim.
- Do not stack firewood against the house, and remove old stumps and buried lumber.
- Replace rotted fascia, decking and sills instead of painting over them.
- Direct downspouts away from the foundation and keep gutters clear before winter.
- Ventilate crawl spaces and add vapor barriers where needed.

Can Spokane homes get termites at all?
It is possible, mostly in very wet or decayed wood, though it is far less common than carpenter ants or wood rot.
Are those swarmers termites or ants?
Check the waist and wings, or save a sample in a jar for the inspector.
Should I buy a termite bond?
Probably not necessary in most of this region. An inspection after a leak or before a purchase is more practical.
Will cold weather keep termites away?
Freezing helps limit them outdoors, but heated structures with moisture can still shelter wood-destroying pests.
