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.
- 1Live pale insects inside a broken mud tube.
- 2Wood that sounds hollow when tapped.
- 3Piles of identical shed wings on windowsills.
- 4Damage found during a remodel or repair.
- 5Discarded wings caught in spider webs.
- 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.

Local termites conditions in Redmond.
Across 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. 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. 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. 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. 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.
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.
Across Redmond, 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. Save a few in a bag, or snap a clear photo. Swarm season is when termites show themselves.
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. The same advice applies across the area, from Redmond out to Kirkland and Bellevue. A lot of houses around Redmond are built over crawl spaces, and that's usually where termites start.
A year of termites in Redmond.
- Winter: a good time to book an inspection in Redmond, before swarm season starts. - Spring and fall: swarm seasons. Across 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.
What happens at an inspection.
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. Most inspections take an hour or two.
Termites or ants?
- 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. - 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.
Getting ready for treatment day.
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. Prep is light for liquid treatments and bait stations.
Mulch and termites.
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. Pull mulch back from the foundation and keep the layer thin.
Questions to ask before you sign.
- What do I need to do before and after treatment? - Which termites did you find, and where? - 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 affects the price
- Warranty type: retreatment only or damage repair.
- Linear feet of foundation to be treated.
- Liquid barrier versus bait station system.
- Slab, crawl space, or basement construction.
- Extent of existing damage needing repair.
- Access to crawl spaces and attics.

What's your biggest concern about termites?
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.

Questions people ask
How do I know if I have termites or flying ants?
Check the wings and the waist. Termite wings are all the same length. Ants have a pinched waist; termites don't. Save one in a bag for the inspector.
Can termites damage a house on a concrete slab?
Yes. They come up through expansion joints, plumbing gaps and small cracks. Inspectors check those spots first.
Do I have to leave my house during termite treatment?
Not for a soil treatment or bait stations. Fumigation is different. Everyone leaves for two to three days, pets and houseplants included.
How long do termite bait stations take to work?
Usually several weeks to a few months. Termites have to find the stations first. Then the bait spreads through the colony.
How long does termite treatment take?
A liquid barrier takes half a day to a day. Bait stations take a few hours to install. Fumigation takes two to three days.
How much does a pre-construction termite treatment cost?
Professionals reported an average of $883. Anyone building a house can use $883 as a rough yardstick for pre-construction termite treatment, the professional-reported average in Pest Control Technology (PCT) magazine's 2025 termite market report (about 145 respondents, 2024 pricing), while remembering that actual quotes depend on slab size, region and product. A good pro in Redmond will explain how their plan fits what they found at your home.
When is termite swarming season?
Across Redmond, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Across 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.
