Homeowners, landlords and anyone buying or selling a house in Vancouver, whether you've spotted something or just want to know what to watch for.
What to look for
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. Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs.
- 1Buckling laminate or warped hardwood flooring.
- 2Blistered or bubbling paint on wood surfaces.
- 3Termite activity reported at a neighbor's home.
- 4Crumbling baseboards behind furniture.
- 5Doors and windows that suddenly stick.
- 6Dry hexagonal pellets under window frames or eaves.
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.

- Best for
- Every job, real estate closings, and yearly peace of mind
Localized Wood, Foam, and Borate Treatment

- 2–4 hours to install; checked quarterly
- Best for
- Colony elimination, wells and slabs, homes near water
Fumigation for Drywood Termites
$1,200–$4,000 (often $1–$4 per square foot)
Tenting is mainly for drywood termites. Most homes here never need it.

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. 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. 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. Around 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. 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.
A downspout that dumps water at the foundation keeps the soil wet year-round. Extend it well away from the house.Which termites live around Vancouver.
It needs steady moisture. It nests in soil and builds mud tubes to reach wood. The termite you're most likely to meet in Vancouver is the western subterranean termite.
When termites swarm here.
Save a few in a bag, or snap a clear photo. A swarm inside usually means it's in the house. A swarm outside means a colony is nearby. Around Vancouver, western subterranean termites usually swarm in spring, and again in fall after the first good rain. Swarm season is when termites show themselves.
Where to look around your house.
Standing water or a musty smell needs fixing either way. Check the piers, the sill plate and the floor joists. Take a flashlight underneath. 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. Around 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.
Ways to keep the cost down.
- Book before swarm season, when schedules fill up. - If you already have a warranty, keep the renewal current. - Ask about both bait and liquid options for your house. - Fix leaks and drainage first. Moisture brings termites back. - Get two or three quotes, and compare what each one covers.
What happens at an inspection.
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. A moisture meter and a probe help them find hidden activity. Afterward, ask them to show you what they found. Photos help.
Termites or ants?
- Tunnels: termite galleries are packed with mud. Ant tunnels are clean and smooth. - Debris: termites leave mud. Carpenter ants leave sawdust. - Antennae: termite antennae are straight. Ant antennae bend like an elbow. - Waist: termites are thick through the middle. Ants are pinched. - Wings: termite wings are all the same length. Ant wings aren’t.
Getting ready for treatment day.
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. 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.
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 do I need to do before and after treatment? - What does the yearly renewal cost? - What does the warranty cover, and for how long? - Is the whole foundation treated, or just one spot? - What product or system will you use? - Which termites did you find, and where?
What affects the price
- Cubic footage under the tent for fumigation.
- Linear feet of foundation to be treated.
- Liquid barrier versus bait station system.
- Warranty type: retreatment only or damage repair.
- Time of year and how booked up local companies are.
- Whole-house fumigation versus spot treatment.
- Access to crawl spaces and attics.
- Wells, drains, or water features limiting chemical use.
📊
What's your biggest concern about termite control costs?
When to call for help
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. Lenders often ask for one. It's also the cheapest termite service. Carpenter ants leave clean tunnels and sawdust. Termites leave mud.
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. With summer highs around 79°F, Vancouver's marine west coast climate decides when local termites are busiest. Not every house gets them, but plenty do. Termites are a steady, moderate risk in Washington. 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.

Simple ways to keep termites away
- Grade soil to slope away from the foundation.
- Ventilate crawl spaces and control humidity.
- Keep gutters clean so water does not pool.
- Keep six inches between soil and siding or wood.
- Caulk gaps around plumbing and utility penetrations.

Questions people ask
Is a bait system cheaper than a liquid treatment?
Ask for both prices. A liquid barrier has no monthly checks. Around Vancouver, bait costs about the same to install, plus a yearly monitoring fee. Not usually upfront.
What does a termite warranty cover?
Ask what's excluded, and whether it transfers if you sell. Others also cover repairs. Some cover re-treatment only. It depends on the plan.
Does homeowner insurance pay for termite damage?
That's why catching it early matters. Most policies treat termite damage as preventable. Usually not.
How much does termite fumigation cost?
Most homes around Vancouver never need it. It's mainly for drywood termites. Usually $1,200–$4,000, often $1–$4 per square foot.
How long do termite bait stations take to work?
Then the bait spreads through the colony. Termites have to find the stations first. Usually several weeks to a few months.
Does fumigation kill subterranean termites too?
It doesn't reach a colony living in the soil. Tenting clears termites inside the house. Not reliably.
Can I treat termites myself?
Store-bought sprays usually kill only what you see. It also needs even coverage around the foundation. The product must reach the whole colony. An active colony is harder. Prevention, yes.
Is termite prevention cheaper than repairing termite damage?
Around Vancouver, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Around 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.
