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.
- 1Damage found during a remodel or repair.
- 2Sagging or spongy floors near exterior walls.
- 3Layered, honeycombed wood packed with soil.
- 4Mud in cracks of subfloor or joists.
- 5Tiny pinholes in drywall rimmed with mud.
- 6Screwdriver sinks easily into sills or trim.
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.

Crawl spaces are where termites usually get in. Joists, piers and the sill plate should all get a close look.How treatment works on a typical Federal Way home.
Bait stations are the other main option. They're spaced every 10 to 20 feet. Termites carry the bait back to the colony. The stations are checked on a schedule, often every few months. With a crawl space, the crew treats soil outside and underneath. They also treat around piers and plumbing. Fix any moisture under the house too.
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.
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.
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. For Federal Way homes, western subterranean termites usually swarm in spring, and again in fall after the first good rain.
Where to look around your house.
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. Take a flashlight underneath.
A year of termites in Federal Way.
- 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. - Winter: a good time to book an inspection in Federal Way, before swarm season starts. - Spring and fall: swarm seasons. For Federal Way homes, swarms often follow the first warm days and the first fall rain.
What happens at an inspection.
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. 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.
Termites or ants?
- 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. - Wings: termite wings are all the same length. Ant wings aren’t.
Getting ready for treatment day.
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. Soil treatments and bait stations need little prep. Clear a path along the outside walls. Move stored boxes away from garage walls.
Mulch and termites.
A dry strip along the house lets you spot mud tubes. Wood chips right against siding hold moisture termites like. Keep mulch thin and pull it back from the foundation.
Questions to ask before you sign.
- 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? - Which termites did you find, and where?
What affects the price
- Liquid barrier versus bait station system.
- Amount of drilling through concrete and patios.
- Annual renewal and monitoring fees.
- 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 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.

Questions people ask
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.
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.
Will termites come back after treatment?
They can. Treatments wear down and new colonies move in. That's what yearly inspections and renewal plans are for.
Does fumigation kill subterranean termites too?
Not reliably. Tenting clears termites inside the house. It doesn't reach a colony living in the soil.
What does a WDI report include?
It lists any termites or damage found. It also notes conditions that invite them, like wood touching soil. It only covers areas the inspector could reach.
Is termite prevention cheaper than repairing termite damage?
For Federal Way homes, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. For Federal Way 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.
Are termites common in Washington?
Around Federal Way, the usual culprit is the western subterranean termite.
