Anyone in Redmond who owns, rents out, or is buying a home and wants to know whether termites are a real concern.
What to look for
Termites work quietly. A colony can feed inside a wall for years. Average winter lows near 36°F slow termites near the surface around Redmond, 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.
- 1Mud in cracks of subfloor or joists.
- 2Dry hexagonal pellets under window frames or eaves.
- 3Crumbling baseboards behind furniture.
- 4Winged swarmers indoors, especially in spring.
- 5Mud tubes running up foundation walls or piers.
- 6Screwdriver sinks easily into sills or trim.
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
- Colony elimination, wells and slabs, homes near water
Localized Wood, Foam, and Borate Treatment
$250–$1,500
Foam termiticide is injected into wall voids liquid cannot reach. In Redmond this pairs well with a soil barrier around tricky slab construction.
- Time

- Best for
- Small drywood spots, wall voids, and exposed framing
Fumigation for Drywood Termites
$1,200–$4,000 (often $1–$4 per square foot)

Local termites conditions in Redmond.
A provider who works Redmond 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 Redmond'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 Redmond usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Around Redmond, 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. Redmond 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.
Subterranean termites don't stop in winter; they just go deeper. A quiet season is a good time for a non-urgent inspection.Which termites live around Redmond.
It needs steady moisture. It nests in soil and builds mud tubes to reach wood. The termite you're most likely to meet in Redmond 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 Redmond, 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.
The same advice applies across the area, from Redmond out to Kirkland and Bellevue. 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 Redmond are built over crawl spaces, and that's usually where termites start.
A year of termites in Redmond.
- Spring and fall: swarm seasons. Around Redmond, swarms often follow the first warm days and the first fall rain. - Summer: with highs around 76°F in Redmond, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 37 inches of rain a year in Redmond, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Redmond, 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 Redmond 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 Redmond 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
- Wells, drains, or water features limiting chemical use.
- Annual renewal and monitoring fees.
- Local labor rates and licensing requirements.
- Amount of drilling through concrete and patios.
- Cubic footage under the tent for fumigation.
- Attached garages, decks, and additions.
- Linear feet of foundation to be treated.
- Species: subterranean, drywood, or Formosan.

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
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. Some of the work is yours. Pull mulch back from the foundation. Fix leaks and clear gutters. Keep firewood away from the house.

- Install a vapor barrier over crawl space soil.
- Use borate-treated or pressure-treated lumber for repairs.
- Set deck and porch posts on concrete, not soil.
- Screen attic and foundation vents with fine mesh.
- Trim shrubs so foundation walls stay visible and dry.

Questions people ask
Why do termite quotes vary so much?
Compare what's included, line by line. Drilling through concrete adds labor. Some include a warranty or yearly checks. Companies measure differently and use different products.
How much does a termite inspection cost?
It's worth asking. Some companies credit it toward treatment if you go ahead. Usually $75–$250.
How much does termite fumigation cost?
Most homes around Redmond never need it. It's mainly for drywood termites. Usually $1,200–$4,000, often $1–$4 per square foot.
Is a bait system cheaper than a liquid treatment?
Ask for both prices. A liquid barrier has no monthly checks. Around Redmond, bait costs about the same to install, plus a yearly monitoring fee. Not usually upfront.
How do I know if I have termites or flying ants?
Save one in a bag for the inspector. Ants have a pinched waist; termites don't. Termite wings are all the same length. Check the wings and the waist.
What does a WDI report include?
It only covers areas the inspector could reach. It also notes conditions that invite them, like wood touching soil. It lists any termites or damage found.
What is the difference between subterranean and drywood termites?
Around Redmond, the subterranean kind causes most problems. Drywood termites live inside the wood and leave tiny pellets. Subterranean termites live in soil and build mud tubes.
Can I treat termites myself instead of hiring a professional?
Around Redmond, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Around Redmond, 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 Redmond, the usual culprit is the western subterranean termite.
