Homeowners, landlords and anyone buying or selling a house in Eugene, whether you've spotted something or just want to know what to watch for.
What to look for
Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs. Termites work quietly. A colony can feed inside a wall for years. Average winter lows near 35°F slow termites near the surface around Eugene, but they move deeper and keep feeding under heated homes.

Why it’s worth acting soon

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 Eugene home.
With a crawl space, the crew treats soil outside and underneath. The stations are checked on a schedule, often every few months. Termites carry the bait back to the colony. They're spaced every 10 to 20 feet. Bait stations are the other main option. Fix any moisture under the house too. They also treat around piers and plumbing.
Which termites live around Eugene.
The termite you're most likely to meet in Eugene is the western subterranean termite. It needs steady moisture. It nests in soil and builds mud tubes to reach wood.
Mulch piled against the house and a dripping hose bib give termites moisture and cover. Pull mulch back and fix the drip.When termites swarm here.
A swarm outside means a colony is nearby. Around Eugene, western subterranean termites usually swarm in spring, and again in fall after the first good rain. Swarm season is when termites show themselves. Save a few in a bag, or snap a clear photo. A swarm inside usually means it's in the house.
Where to look around your house.
Check the piers, the sill plate and the floor joists. Take a flashlight underneath. A lot of houses around Eugene are built over crawl spaces, and that's usually where termites start. The same advice applies across the area, from Eugene out to Springfield and Corvallis. Standing water or a musty smell needs fixing either way.
A year of termites in Eugene.
- Spring and fall: swarm seasons. Around Eugene, swarms often follow the first warm days and the first fall rain. - Winter: a good time to book an inspection in Eugene, before swarm season starts. - Fall: with about 47 inches of rain a year in Eugene, make sure gutters and downspouts carry water well away from the foundation. - Summer: with highs around 83°F in Eugene, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs.
What happens at an inspection.
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. 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.
Termites or ants?
- Waist: termites are thick through the middle. Ants are pinched. - Wings: termite wings are all the same length. Ant wings aren’t. - 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.
Getting ready for treatment day.
Move boxes away from garage walls. Clear a walking path along the exterior walls. Prep is light for liquid treatments and bait stations. Drill holes in slabs or patios get patched afterward. Keep kids and pets inside while the Eugene crew applies the product, and ask how long to stay off treated soil. In Oregon, pacific dampwood swarms late summer or fall; western subterranean may swarm any time of year (Oregon State). Flag sprinkler heads and buried lines.
Mulch and termites.
A dry gap along the house makes mud tubes easier to spot; in Eugene that means extending downspouts and pulling mulch back from the slab. Pull mulch back from the foundation and keep the layer thin. Wood chips touching the siding trap the moisture termites are after.
Questions to ask before you sign.
- What product or system will you use? - Which termites did you find, and where? - 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 affects the price
- Species: subterranean, drywood, or Formosan.
- Liquid barrier versus bait station system.
- Cubic footage under the tent for fumigation.
- Amount of drilling through concrete and patios.
- Whole-house fumigation versus spot treatment.
- Extent of existing damage needing repair.

What's your biggest concern about termites?
When to call for help
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. Lenders often ask for one. It's also the cheapest termite service. Carpenter ants leave clean tunnels and sawdust. Termites leave mud.
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.
Termites in Eugene
Eugene has a mediterranean climate, and termites activity here tends to pick up spring swarm season (March-May), warmer earlier in the south. Around Eugene, 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. Around Eugene, take a minute to note where you have seen activity and when it appears, so the inspection is faster and the quote more accurate. A local provider who knows Eugene and Oregon can point out the specific conditions that matter most here before you commit to a plan. Around Eugene, before you book, ask whether the inspection is included, what the treatment plan covers, how many visits to expect, and what the written quote includes.

- Pacific dampwood termite (Zootermopsis angusticollis) — Oregon State: 'consumes and nests inside moist, water-damaged wood'; swarms 'during late summer or fall'. A moisture problem, not a soil problem, is the usual root cause.
When termites are busiest around Eugene
Pacific dampwood swarms late summer or fall; western subterranean may swarm any time of year (Oregon State).
Oregon State: both species 'cause damage to structures in the Pacific Northwest'; control 'is best left to professional pest controllers'.

Simple ways to keep termites away
- Set deck and porch posts on concrete, not soil.
- Inspect used furniture for drywood pellets before bringing indoors.
- Grade soil to slope away from the foundation.
- Ventilate crawl spaces and control humidity.
- Keep six inches between soil and siding or wood.
- Screen attic and foundation vents with fine mesh.
A liquid soil treatment goes into a trench along the foundation so termites cross it on their way to the house.Did you know?

Questions people ask
Can I treat termites myself?
The product must reach the whole colony. It also needs even coverage around the foundation. Store-bought sprays usually kill only what you see. Prevention, yes. An active colony is harder.
How do I choose a termite company?
Ask what the warranty covers. Compare the proposals, not just the totals. Make sure they're licensed in Oregon. Ask which termites they found and what product they'll use.
Is termite treatment safe for kids and pets?
Bait stations are locked and buried. Ask for the label and follow any re-entry times. Used according to the label, yes. Soil treatments stay in the ground.
How long does termite treatment take?
Bait stations take a few hours to install. Fumigation takes two to three days. A liquid barrier takes half a day to a day.
Can I pay for termite monitoring without a full treatment?
Around Eugene, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Around Eugene, 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 Oregon?
Around Eugene, the usual culprit is the western subterranean termite.
