The short version
Most termite problems in Vancouver are western subterranean termites, and the usual fix is a liquid soil treatment or bait stations. Start with an inspection; $75–$250 is typical.
- Look for mud tubes, shed wings and hollow-sounding wood.
- Swarms usually show up in spring.
- The usual fix is a soil barrier or bait stations.
- An inspection typically costs $75–$250.
- Insurance usually doesn’t cover termite damage.
Anyone in Vancouver 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. Average winter lows near 34°F slow termites near the surface around Vancouver, but they move deeper and keep feeding under heated homes.
- 1Discarded wings caught in spider webs.
- 2Small kick-out holes in exposed wood.
- 3Piles of identical shed wings on windowsills.
- 4Winged swarmers indoors, especially in spring.
- 5Termite activity reported at a neighbor's home.
- 6Mud in cracks of subfloor 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.

It needs steady moisture. The termite you're most likely to meet in Vancouver is the western subterranean termite. It nests in soil and builds mud tubes to reach wood.
Local termites conditions in Vancouver.
A provider who works Vancouver 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. Vancouver sits in a marine west coast climate, and that sets the pace for termite activity here: spring swarm season (March-May), warmer earlier in the south. Across Vancouver, 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 Vancouver usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Vancouver'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.
Mulch piled against the house and a dripping hose bib give termites moisture and cover. Pull mulch back and fix the drip.When termites swarm here.
Save a few in a bag, or snap a clear photo. Swarm season is when termites show themselves. Across Vancouver, 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.
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 lot of houses around Vancouver are built over crawl spaces, and that's usually where termites start.
A year of termites in Vancouver.
- Spring and fall: swarm seasons. Across Vancouver, swarms often follow the first warm days and the first fall rain. - Summer: with highs around 79°F in Vancouver, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 42 inches of rain a year in Vancouver, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Vancouver, before swarm season starts.
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 Vancouver 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 Vancouver that means extending downspouts and pulling mulch back from the slab. 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
- Local labor rates and licensing requirements.
- Liquid barrier versus bait station system.
- Whole-house fumigation versus spot treatment.
- Species: subterranean, drywood, or Formosan.
- Slab, crawl space, or basement construction.
- Attached garages, decks, and additions.

What's your biggest concern about termites?
When to call for help
Termites leave mud. Carpenter ants leave clean tunnels and sawdust. It's also the cheapest termite service. Lenders often ask for one. Get a wood-destroying insect (WDI) report either way. Buying or selling? Hollow-sounding wood is another clue. Call if you see mud tubes, pellets or an indoor swarm.
What you can do yourself
Some of the work is yours. Pull mulch back from the foundation. Fix leaks and clear gutters. Keep firewood away from the house. Treating an active colony is harder. The product has to reach the whole colony. It also needs even coverage around the entire foundation. Store-bought sprays usually kill only the termites you see.
Termites in Vancouver
A typical home in Vancouver is worth around $480k, which puts a few hundred dollars for an inspection and prevention in perspective. Vancouver has a marine west coast climate, and termites activity here tends to pick up spring swarm season (March-May), warmer earlier in the south. Across Vancouver, most of the housing is urban, so the usual entry points, moisture spots, and sheltered areas near the structure are what an inspection checks first. Across Vancouver, take a minute to note where you have seen activity and when it appears, so the inspection is faster and the quote more accurate. A local provider who knows Vancouver and Washington can point out the specific conditions that matter most here before you commit to a plan. About 42 inches of rain a year in Vancouver is plenty for subterranean termites, especially on any side of the house kept damp by gutters or sprinklers. Termites are a steady, moderate risk in Washington. Not every house gets them, but plenty do. With summer highs around 79°F, Vancouver's marine west coast climate decides when local termites are busiest.

Simple ways to keep termites away
- Use borate-treated or pressure-treated lumber for repairs.
- Never leave form boards or scrap lumber in the soil.
- Trim shrubs so foundation walls stay visible and dry.
- Fix leaking hose bibs, faucets, and pipes promptly.
- Keep six inches between soil and siding or wood.
Keep the inspection diagram, treatment record and warranty together. Buyers and inspectors will ask for them later.Did you know?
Across Vancouver, when danger shows up, soldier termites bang their heads against the tunnel walls to warn the colony.
Questions people ask
Can termites damage a house on a concrete slab?
They come up through expansion joints, plumbing gaps and small cracks. Inspectors check those spots first. Yes.
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.
Does fumigation kill subterranean termites too?
Tenting clears termites inside the house. It doesn't reach a colony living in the soil. Not reliably.
What is the difference between subterranean and drywood termites?
Drywood termites live inside the wood and leave tiny pellets. Around Vancouver, the subterranean kind causes most problems. Subterranean termites live in soil and build mud tubes.
Do I need a termite inspection when buying a house?
Either way, it's cheap peace of mind. Ask your agent when it's due. Usually, yes. Many lenders ask for a wood-destroying insect (WDI) report.
Across Vancouver, can a pest control company do a termite inspection for a home sale?
Across Vancouver, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Across Vancouver, 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 Vancouver, the usual culprit is the western subterranean termite.
