Homeowners, landlords and anyone buying or selling a house in Federal Way, 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 37°F slow termites near the surface around Federal Way, 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.

Why it’s worth acting soon

- Homeowners insurance usually doesn’t cover termite damage.

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

Local termites conditions in Federal Way.
Across Federal Way, 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 Federal Way usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Federal Way'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 Federal Way 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. Federal Way 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.Which termites live around Federal Way.
It nests in soil and builds mud tubes to reach wood. It needs steady moisture. The termite you're most likely to meet in Federal Way is the western subterranean termite.
When termites swarm here.
Across Federal Way, 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 Federal Way out to Auburn and Kent. A lot of houses around Federal Way are built over crawl spaces, and that's usually where termites start.
A year of termites in Federal Way.
- Winter: a good time to book an inspection in Federal Way, before swarm season starts. - Spring and fall: swarm seasons. Across Federal Way, swarms often follow the first warm days and the first fall rain. - Summer: with highs around 76°F in Federal Way, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 41 inches of rain a year in Federal Way, make sure gutters and downspouts carry water well away from the foundation.
Ways to keep the cost down.
- 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. - If you already have a warranty, keep the renewal current.
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 Federal Way 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 Federal Way 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
- Liquid barrier versus bait station system.
- Time of year and how booked up local companies are.
- Linear feet of foundation to be treated.
- Species: subterranean, drywood, or Formosan.
- Slab, crawl space, or basement construction.
- Attached garages, decks, and additions.
- Access to crawl spaces and attics.
- Amount of drilling through concrete and patios.

What's your biggest concern about termite control costs?
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
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 much does termite treatment cost?
Most liquid treatments run about $1,200–$3,500. Across Federal Way, bait systems cost about the same to install, plus $300–$500 a year. The size of the house matters most.
Does homeowner insurance pay for termite damage?
Usually not. Most policies treat termite damage as preventable. That's why catching it early matters.
Is a bait system cheaper than a liquid treatment?
Not usually upfront. Across Federal Way, bait costs about the same to install, plus a yearly monitoring fee. A liquid barrier has no monthly checks. Ask for both prices.
What does a termite warranty cover?
It depends on the plan. Some cover re-treatment only. Others also cover repairs. Ask what's excluded, and whether it transfers if you sell.
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 Federal Way, the subterranean kind causes most problems.
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 often does a termite treatment need a callback?
Across Federal Way, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Across Federal Way, 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 Federal Way, the usual culprit is the western subterranean termite.
