The short version
Most termite problems in Tacoma are western subterranean termites, and the usual fix is a liquid soil treatment or bait stations. Start with an inspection; $75–$250 is typical.
- Look for mud tubes, shed wings and hollow-sounding wood.
- Swarms usually show up in spring.
- The usual fix is a soil barrier or bait stations.
- An inspection typically costs $75–$250.
- Insurance usually doesn’t cover termite damage.
Anyone in Tacoma 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 Tacoma, 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.
- 1Tiny pinholes in drywall rimmed with mud.
- 2Damage found during a remodel or repair.
- 3Buckling laminate or warped hardwood flooring.
- 4Blistered or bubbling paint on wood surfaces.
- 5Small kick-out holes in exposed wood.
- 6Winged swarmers indoors, especially in spring.
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.

Liquid Soil Termiticide Barrier
$1,200–$3,500 (often $3–$16 per linear foot)

Local termites conditions in Tacoma.
A provider who works Tacoma 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 Tacoma'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 Tacoma usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Around Tacoma, 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. Tacoma 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.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 Tacoma, 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 Tacoma out to Federal Way and Auburn. 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 Tacoma are built over crawl spaces, and that's usually where termites start.
A year of termites in Tacoma.
- Winter: a good time to book an inspection in Tacoma, before swarm season starts. - Fall: with about 40 inches of rain a year in Tacoma, make sure gutters and downspouts carry water well away from the foundation. - Summer: with highs around 77°F in Tacoma, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Spring and fall: swarm seasons. Around Tacoma, swarms often follow the first warm days and the first fall rain.
What happens at an inspection.
Photos help. Afterward, ask them to show you what they found. A moisture meter and a probe help them find hidden activity. They'll also go into the crawl space. Inside, they check the garage, baseboards, plumbing gaps and the attic. They check the foundation, the soil line and nearby wood. The inspector walks the outside of the house first. Most inspections take an hour or two.
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.
Drill holes in slabs or patios get patched afterward. Keep kids and pets inside while the Tacoma 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). Flag sprinkler heads and buried lines. Move boxes away from garage walls. Clear a walking path along the exterior walls. Prep is light for liquid treatments and bait stations.
Mulch and termites.
Wood chips touching the siding trap the moisture termites are after. A dry gap along the house makes mud tubes easier to spot; in Tacoma that means extending downspouts and pulling mulch back from the slab. 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? - 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
- Liquid barrier versus bait station system.
- Cubic footage under the tent for fumigation.
- Extent of existing damage needing repair.
- Linear feet of foundation to be treated.
- Slab, crawl space, or basement construction.
- 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.

Simple ways to keep termites away
- Ventilate crawl spaces and control humidity.
- Repair rotting trim, fascia, and window frames.
- Store firewood well away from the house, off the ground.
- Grade soil to slope away from the foundation.
- Paint or seal exposed exterior wood.
- Use borate-treated or pressure-treated lumber for repairs.
Keep the inspection diagram, treatment record and warranty together. Buyers and inspectors will ask for them later.Did you know?

Around Tacoma, when danger shows up, soldier termites bang their heads against the tunnel walls to warn the colony.
Questions people ask
What is the difference between subterranean and drywood termites?
Subterranean termites live in soil and build mud tubes. Drywood termites live inside the wood and leave tiny pellets. Around Tacoma, the subterranean kind causes most problems.
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 do I choose a termite company?
Make sure they're licensed in Washington. Ask which termites they found and what product they'll use. Ask what the warranty covers. Compare the proposals, not just the totals.
Does fumigation kill subterranean termites too?
Not reliably. Tenting clears termites inside the house. It doesn't reach a colony living in the soil.
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.
What are the signs of termites that homeowners miss?
Around Tacoma, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Around Tacoma, 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 Tacoma, the usual culprit is the western subterranean termite.
