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
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. Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs.

- 2Piles of identical shed wings on windowsills.
- 3Mud in cracks of subfloor or joists.
- 4Mud tubes running up foundation walls or piers.
- 5Layered, honeycombed wood packed with soil.
- 6Crumbling baseboards behind furniture.
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 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. In Kirkland, 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.
Sealing the gap where pipes enter the house takes away one of the easiest routes in. It won't replace treatment, but it helps.When termites swarm here.
Swarm season is when termites show themselves. In Kirkland, 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.
- Spring and fall: swarm seasons. In Kirkland, 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. - 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.
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?
- 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. - Tunnels: termite galleries are packed with mud. Ant tunnels are clean and smooth.
Getting ready for treatment day.
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. 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.
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.
- 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 do I need to do before and after treatment?
What affects the price
- Cubic footage under the tent for fumigation.
- Access to crawl spaces and attics.
- Warranty type: retreatment only or damage repair.
- Extent of existing damage needing repair.
- Time of year and how booked up local companies are.
- Wells, drains, or water features limiting chemical use.

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
Store-bought sprays usually kill only the termites you see. It also needs even coverage around the entire foundation. The product has to reach the whole colony. Treating an active colony is harder. Keep firewood away from the house. Fix leaks and clear gutters. Pull mulch back from the foundation. Some of the work is yours.
