Homeowners, landlords and anyone buying or selling a house in Kirkland, whether you've spotted something or just want to know what to watch for.
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 36°F slow termites near the surface around Kirkland, but they move deeper and keep feeding under heated homes.

- Every job, real estate closings, and yearly peace of mind
Liquid Soil Termiticide Barrier
$1,200–$3,500 (often $3–$16 per linear foot)
A liquid barrier treatment around a Kirkland home means trenching and rodding termiticide into the soil along the foundation. Non-repellent products let termites pass through and carry the chemical home to the colony under Kirkland.

- Half a day to a full day
- Best for
- Active subterranean termites; fast knockdown around the foundation
Bait Station System with Monitoring
$1,500–$3,500 install, plus $300–$500 per year

- Best for
- Colony elimination, wells and slabs, homes near water
Fumigation for Drywood Termites
$1,200–$4,000 (often $1–$4 per square foot)

Local termites conditions in Kirkland.
Kirkland 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. For Kirkland homes, the area is mostly suburban, 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 Kirkland usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Kirkland'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 Kirkland 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.
Mulch piled against the house and a dripping hose bib give termites moisture and cover. Pull mulch back and fix the drip.Which termites live around Kirkland.
It needs steady moisture. The termite you're most likely to meet in Kirkland is the western subterranean termite. It nests in soil and builds mud tubes to reach wood.
When termites swarm here.
Swarm season is when termites show themselves. For Kirkland homes, 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.
Where to look around your house.
A lot of houses around Kirkland 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. The same advice applies across the area, from Kirkland out to Bellevue and Redmond.
A year of termites in Kirkland.
- Fall: with about 38 inches of rain a year in Kirkland, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Kirkland, before swarm season starts. - Spring and fall: swarm seasons. For Kirkland homes, swarms often follow the first warm days and the first fall rain. - Summer: with highs around 76°F in Kirkland, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs.
Ways to keep the cost down.
- 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. - Fix leaks and drainage first. Moisture brings termites back. - Ask about both bait and liquid options for your house.
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?
- 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. - Waist: termites are thick through the middle. Ants are pinched. - Antennae: termite antennae are straight. Ant antennae bend like an elbow.
Getting ready for treatment day.
Keep pets and kids inside while the crew works outside. Ask how long to stay off treated soil. Any drill holes in a slab or patio get patched. Soil treatments and bait stations need little prep. Clear a path along the outside walls. Move stored boxes away from garage walls. Mark sprinkler heads and any buried lines.
Mulch and termites.
Keep mulch thin and pull it back from the foundation. A dry strip along the house lets you spot mud tubes. Wood chips right against siding hold moisture termites like.
Questions to ask before you sign.
- 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 product or system will you use? - Is the whole foundation treated, or just one spot?
What affects the price
- Number of bait stations required.
- Wells, drains, or water features limiting chemical use.
- Attached garages, decks, and additions.
- Amount of drilling through concrete and patios.
- Slab, crawl space, or basement construction.
- Extent of existing damage needing repair.
- Whole-house fumigation versus spot treatment.
- Cubic footage under the tent for fumigation.

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
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.

Questions people ask
How much does a termite inspection cost?
Some companies credit it toward treatment if you go ahead. It's worth asking. Usually $75–$250.
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.
Why do termite quotes vary so much?
Drilling through concrete adds labor. Compare what's included, line by line. Companies measure differently and use different products. Some include a warranty or yearly checks.
What does a termite warranty cover?
Others also cover repairs. Ask what's excluded, and whether it transfers if you sell. It depends on the plan. Some cover re-treatment only.
How do I know if I have termites or flying ants?
Ants have a pinched waist; termites don't. Save one in a bag for the inspector. Check the wings and the waist. Termite wings are all the same length.
What is the difference between subterranean and drywood termites?
Drywood termites live inside the wood and leave tiny pellets. Around Kirkland, the subterranean kind causes most problems. Subterranean termites live in soil and build mud tubes.
Is termite prevention cheaper than repairing termite damage?
For Kirkland homes, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. For Kirkland homes, 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.
Is termite fumigation common?
A homeowner quoted a tent job is buying a specialist service. Before work starts in Kirkland, ask how many visits are included and what happens if the termites come back. No. Whole-house tenting is the exception, not the rule: 16% of locations in PCT magazine's 2025 termite market report (about 145 pest-control professionals, 2024 operations) offered fumigation.
