Anyone in Spokane who owns, rents out, or is buying a home and wants to know whether termites are a real concern.
What to look for
Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs. Termites work quietly. A colony can feed inside a wall for years. Winter lows around Spokane average near 23°F, so termites retreat deeper into the soil, though colonies under heated basements can stay active all winter.

- 3Discarded wings caught in spider webs.
- 4Termite tubes hanging down from ceilings or joists.

Why it’s worth acting soon
- Colonies grow and spread every year they go untreated.
- Damage hides behind drywall, flooring and trim.
- Homeowners insurance usually doesn’t cover termite damage.
- An active infestation can complicate a home sale.

Treatment options and typical costs
Termite Inspection and WDI Report
$75–$250
The inspector checks the foundation, garage, attic and damp spots. Bring up anything you’ve noticed.
- Time
- 60–120 minutes
- Best for
- Every job, real estate closings, and yearly peace of mind
Bait Station System with Monitoring
$1,500–$3,500 install, plus $300–$500 per year
Bait stations are set into the ground every 10 to 20 feet around a Spokane home. Foraging workers carry the slow-acting bait home, and the colony collapses.
- Time
- 2–4 hours to install; checked quarterly
- Best for
- Colony elimination, wells and slabs, homes near water
Annual Renewal and Monitoring
$150–$400 per year
Termites do not stop foraging after a treatment, so monitoring matters. Yearly visits to a Spokane home catch new tubes before they reach framing.
- Time
- 30–60 minutes per visit
- Best for
- Keeping a treated home protected after the initial job
Localized Wood, Foam, and Borate Treatment
$250–$1,500
A local treatment is cheaper than fumigation but only covers what the Spokane technician can find. Hidden drywood galleries elsewhere in the house are not touched.
- Time

Local termites conditions in Spokane.
A provider who works Spokane and Washington every day can point out the specific conditions that matter most here, and getting the scope, price, and follow-up terms in writing makes it easier to compare options. Spokane sits in a warm summer continental climate, and that sets the pace for termite activity here: spring swarm season (March-May), warmer earlier in the south. Across Spokane, the area is mostly urban, so termites pressure can differ from one block to the next depending on how tight the entry points are and how much food, water, or shelter is close by. An inspection in Spokane usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Spokane's seasonal timing lets you schedule treatment before the busy stretch rather than after it, which usually means faster service and a more accurate quote.
Sealing the gap where pipes enter the house takes away one of the easiest routes in. It won't replace treatment, but it helps.Which termites live around Spokane.
It needs steady moisture. The termite you're most likely to meet in Spokane is the western subterranean termite. It nests in soil and builds mud tubes to reach wood.
When termites swarm here.
Save a few in a bag, or snap a clear photo. Swarm season is when termites show themselves. Across Spokane, western subterranean termites usually swarm in spring, and again in fall after the first good rain. A swarm outside means a colony is nearby. A swarm inside usually means it's in the house.
Where to look around your house.
The same advice applies across the area, from Spokane out to Spokane Valley. A lot of houses around Spokane are built over crawl spaces, and that's usually where termites start. Take a flashlight underneath. Check the piers, the sill plate and the floor joists. Standing water or a musty smell needs fixing either way.
A year of termites in Spokane.
- Spring and fall: swarm seasons. Across Spokane, swarms often follow the first warm days and the first fall rain. - Summer: with highs around 84°F in Spokane, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 17 inches of rain a year in Spokane, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Spokane, before swarm season starts.
Ways to keep the cost down.
- Fix leaks and drainage first. Moisture brings termites back. - Ask about both bait and liquid options for your house. - If you already have a warranty, keep the renewal current. - Book before swarm season, when schedules fill up. - Get two or three quotes, and compare what each one covers.
What happens at an inspection.
A moisture meter and a probe help them find hidden activity. Afterward, ask them to show you what they found. Photos help. Most inspections take an hour or two. The inspector walks the outside of the house first. They check the foundation, the soil line and nearby wood. Inside, they check the garage, baseboards, plumbing gaps and the attic. They'll also go into the crawl space.
Termites or ants?
- Waist: termites are thick through the middle. Ants are pinched. - Antennae: termite antennae are straight. Ant antennae bend like an elbow. - Debris: termites leave mud. Carpenter ants leave sawdust. - Tunnels: termite galleries are packed with mud. Ant tunnels are clean and smooth. - Wings: termite wings are all the same length. Ant wings aren’t.
Getting ready for treatment day.
Keep kids and pets inside while the Spokane crew applies the product, and ask how long to stay off treated soil. In Washington, pacific dampwood swarms late summer or fall; western subterranean may swarm any time of year (Oregon State). Drill holes in slabs or patios get patched afterward. Prep is light for liquid treatments and bait stations. Clear a walking path along the exterior walls. Move boxes away from garage walls. Flag sprinkler heads and buried lines.
Mulch and termites.
Pull mulch back from the foundation and keep the layer thin. A dry gap along the house makes mud tubes easier to spot; in Spokane's dry climate the risk is irrigation and leaky hose bibs rather than rain. Wood chips touching the siding trap the moisture termites are after.
Questions to ask before you sign.
- What product or system will you use? - Is the whole foundation treated, or just one spot? - What does the warranty cover, and for how long? - What does the yearly renewal cost? - What do I need to do before and after treatment? - Which termites did you find, and where?
What affects the price
- Liquid barrier versus bait station system.
- Time of year and how booked up local companies are.
- Warranty type: retreatment only or damage repair.
- Annual renewal and monitoring fees.
- Access to crawl spaces and attics.
- Species: subterranean, drywood, or Formosan.
- Linear feet of foundation to be treated.
- Extent of existing damage needing repair.

What's your biggest concern about termite control costs?
When to call for help
Lenders often ask for one. It's also the cheapest termite service. Carpenter ants leave clean tunnels and sawdust. Termites leave mud. Call if you see mud tubes, pellets or an indoor swarm. Hollow-sounding wood is another clue. Buying or selling? Get a wood-destroying insect (WDI) report either way.
What you can do yourself
Store-bought sprays usually kill only the termites you see. It also needs even coverage around the entire foundation. The product has to reach the whole colony. Treating an active colony is harder. Keep firewood away from the house. Fix leaks and clear gutters. Pull mulch back from the foundation. Some of the work is yours.
Termites in Spokane
Not every house gets them, but plenty do. With summer highs around 84°F, Spokane's warm summer continental climate decides when local termites are busiest. A typical home in Spokane is worth around $370k, which puts a few hundred dollars for an inspection and prevention in perspective. Spokane only sees about 17 inches of rain a year, so local termites gather wherever water collects, like sprinkler zones, hose bibs and AC drain lines. Termites are a steady, moderate risk in Washington.

- Paint or seal exposed exterior wood.
- Seal cracks in the foundation and slab.
- Inspect used furniture for drywood pellets before bringing indoors.
- Keep six inches between soil and siding or wood.
- Keep the termite renewal contract current after treatment.
- Caulk gaps around plumbing and utility penetrations.
Keep the inspection diagram, treatment record and warranty together. Buyers and inspectors will ask for them later.Did you know?

Questions people ask
How much does termite treatment cost?
Across Spokane, bait systems cost about the same to install, plus $300–$500 a year. The size of the house matters most. Most liquid treatments run about $1,200–$3,500.
How much does annual termite renewal cost?
It keeps the warranty active and includes a yearly check. Letting it lapse usually ends the warranty. Usually $150–$400 a year.
Is a bait system cheaper than a liquid treatment?
A liquid barrier has no monthly checks. Ask for both prices. Not usually upfront. Across Spokane, bait costs about the same to install, plus a yearly monitoring fee.
How much does termite fumigation cost?
It's mainly for drywood termites. Most homes around Spokane never need it. Usually $1,200–$4,000, often $1–$4 per square foot.
Does fumigation kill subterranean termites too?
Tenting clears termites inside the house. It doesn't reach a colony living in the soil. Not reliably.
Do I have to leave my house during termite treatment?
Fumigation is different. Everyone leaves for two to three days, pets and houseplants included. Not for a soil treatment or bait stations.
Are mud tubes always a sign of active termites?
Break off a piece and check back in a week. If it's rebuilt, they're active. Not always. Old tubes can stay on a wall for years.
Can I treat termites myself instead of hiring a professional?
Across Spokane, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Across Spokane, a professional inspection looks for mud tubes, damaged wood, and swarming activity, and treatment targets the soil and the colony rather than just the visible wood.
Are termites common in Washington?
Around Spokane, the usual culprit is the western subterranean termite.
