- Insurance usually doesn’t cover termite damage.
Homeowners, landlords and anyone buying or selling a house in Kent, 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 Kent, 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.
- 1Discarded wings caught in spider webs.
- 2Layered, honeycombed wood packed with soil.
- 3Termite tubes hanging down from ceilings or joists.
- 4Live pale insects inside a broken mud tube.
- 5Dry hexagonal pellets under window frames or eaves.
- 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.
📅
Termite activity through the year in Kent
Spring
swarm seasons. Around Kent, swarms often follow the first warm days and the first fall rain.
Summer
with highs around 77°F in Kent, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs.
Fall
with about 39 inches of rain a year in Kent, make sure gutters and downspouts carry water well away from the foundation.
Winter
a good time to book an inspection in Kent, before swarm season starts.
Treatment options and typical costs
Termite Inspection and WDI Report
$75–$250
The inspector checks the foundation, garage, attic and damp spots. Bring up anything you’ve noticed.
- Time
- 60–120 minutes
- Best for
- Every job, real estate closings, and yearly peace of mind
Annual Renewal and Monitoring
$150–$400 per year
Ask what a renewal in Kent actually includes, and whether it covers retreatment or repairs. A retreatment-only plan is common; damage repair coverage costs more.
- Time
- 30–60 minutes per visit
- Best for

Liquid Soil Termiticide Barrier
$1,200–$3,500 (often $3–$16 per linear foot)
A liquid barrier treatment around a Kent 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 Kent.
- Time
- 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
Instead of a chemical barrier, baiting in Kent removes the colony itself. Stations are checked on a schedule, commonly quarterly, and refilled.
- Time
- 2–4 hours to install; checked quarterly
- Best for
- Colony elimination, wells and slabs, homes near water
Prices are typical published ranges. Ask what’s included before you compare quotes.
Cardboard boxes stacked on a garage slab are termite food sitting right on their doorstep. Keep storage on shelves.How treatment works on a typical Kent home.
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. 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.
Which termites live around Kent.
It needs steady moisture. It nests in soil and builds mud tubes to reach wood. The termite you're most likely to meet in Kent is the western subterranean termite.
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 Kent, 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 Kent out to Auburn and Federal Way. 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 Kent are built over crawl spaces, and that's usually where termites start.
A year of termites in Kent.
- Spring and fall: swarm seasons. Around Kent, swarms often follow the first warm days and the first fall rain. - Summer: with highs around 77°F in Kent, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 39 inches of rain a year in Kent, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Kent, 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?
- 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.
Prep is light for liquid treatments and bait stations. 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 Kent 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.
Mulch and termites.
Pull mulch back from the foundation and keep the layer thin. A dry gap along the house makes mud tubes easier to spot; in Kent that means extending downspouts and pulling mulch back from the slab. Wood chips touching the siding trap the moisture termites are after.
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
- Number of bait stations required.
- Species: subterranean, drywood, or Formosan.
- Local labor rates and licensing requirements.
- Annual renewal and monitoring fees.
- Slab, crawl space, or basement construction.
- Amount of drilling through concrete and patios.

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
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.
Termites in Kent
A local provider who knows Kent and Washington can point out the specific conditions that matter most here before you commit to a plan. Around Kent, take a minute to note where you have seen activity and when it appears, so the inspection is faster and the quote more accurate. Around Kent, most of the housing is urban, so the usual entry points, moisture spots, and sheltered areas near the structure are what an inspection checks first. Kent has a marine west coast climate, and termites activity here tends to pick up spring swarm season (March-May), warmer earlier in the south. A typical home in Kent is worth around $550k, which puts a few hundred dollars for an inspection and prevention in perspective. With summer highs around 77°F, Kent's marine west coast climate decides when local termites are busiest. Not every house gets them, but plenty do. Termites are a steady, moderate risk in Washington. About 39 inches of rain a year in Kent is plenty for subterranean termites, especially on any side of the house kept damp by gutters or sprinklers.

Simple ways to keep termites away
- Install a vapor barrier over crawl space soil.
- Store firewood well away from the house, off the ground.
- Caulk gaps around plumbing and utility penetrations.
- Keep mulch at least a foot from the foundation.
- Grade soil to slope away from the foundation.
- Repair rotting trim, fascia, and window frames.
Keep the inspection diagram, treatment record and warranty together. Buyers and inspectors will ask for them later.Did you know?
Around Kent, soldier termites can't feed themselves, so the workers feed them mouth to mouth.
Questions people ask
Do I need a termite inspection when buying a house?
Ask your agent when it's due. Either way, it's cheap peace of mind. Many lenders ask for a wood-destroying insect (WDI) report. Usually, yes.
Can termites damage a house on a concrete slab?
Inspectors check those spots first. They come up through expansion joints, plumbing gaps and small cracks. Yes.
Can I treat termites myself?
Store-bought sprays usually kill only what you see. It also needs even coverage around the foundation. The product must reach the whole colony. An active colony is harder. Prevention, yes.
Will termites come back after treatment?
That's what yearly inspections and renewal plans are for. Treatments wear down and new colonies move in. They can.
Is termite treatment safe for kids and pets?
Ask for the label and follow any re-entry times. Bait stations are locked and buried. Soil treatments stay in the ground. Used according to the label, yes.
When is termite swarming season?
Around Kent, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Around Kent, 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 Kent, the usual culprit is the western subterranean termite.
