Homeowners, landlords and anyone buying or selling a house in Keizer, 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 36°F slow termites near the surface around Keizer, but they move deeper and keep feeding under heated homes.

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
Localized Wood, Foam, and Borate Treatment
$250–$1,500
When termites are limited to one wall or window frame, a technician can treat that wood directly, which is common when Keizer subterranean termites reach a damp sill plate. Foam expands into voids, and borate soaks into bare lumber.
- Time
- 1–3 hours
- Best for
- Small drywood spots, wall voids, and exposed framing
Bait Station System with Monitoring
$1,500–$3,500 install, plus $300–$500 per year
Each station holds cellulose bait laced with a chitin synthesis inhibitor. Workers around a Keizer home share it, cannot molt, and the colony dies over weeks to months.
- Time
- 2–4 hours to install; checked quarterly
- Best for
- Colony elimination, wells and slabs, homes near water
Annual Renewal and Monitoring
$150–$400 per year
Bait systems require monitoring to keep working. A Keizer pro checks each station, replaces consumed bait, and notes any new activity around the house.
- Time
- 30–60 minutes per visit
- Best for
- Keeping a treated home protected after the initial job

Local termites conditions in Keizer.
An inspection in Keizer usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Around Keizer, 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. Keizer sits in a mediterranean climate, and that sets the pace for termite activity here: spring swarm season (March-May), warmer earlier in the south. A provider who works Keizer and Oregon 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 Keizer'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.
Subterranean termites don't stop in winter; they just go deeper. A quiet season is a good time for a non-urgent inspection.Which termites live around Keizer.
The termite you're most likely to meet in Keizer is the western subterranean termite. It needs steady moisture. It nests in soil and builds mud tubes to reach wood.
When termites swarm here.
A swarm outside means a colony is nearby. Around Keizer, 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 Keizer are built over crawl spaces, and that's usually where termites start. The same advice applies across the area, from Keizer out to Salem and Albany. Standing water or a musty smell needs fixing either way.
A year of termites in Keizer.
- Spring and fall: swarm seasons. Around Keizer, swarms often follow the first warm days and the first fall rain. - Winter: a good time to book an inspection in Keizer, before swarm season starts. - Fall: with about 42 inches of rain a year in Keizer, make sure gutters and downspouts carry water well away from the foundation. - Summer: with highs around 82°F in Keizer, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs.
Ways to keep the cost down.
- Fix leaks and drainage first. Moisture brings termites back. - Get two or three quotes, and compare what each one covers. - Book before swarm season, when schedules fill up. - If you already have a warranty, keep the renewal current. - Ask about both bait and liquid options for your house.
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 Keizer 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 Keizer 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
- Wells, drains, or water features limiting chemical use.
- Extent of existing damage needing repair.
- Whole-house fumigation versus spot treatment.
- Annual renewal and monitoring fees.
- Local labor rates and licensing requirements.
- Amount of drilling through concrete and patios.
- Attached garages, decks, and additions.
- Linear feet of foundation to be treated.
📊
What's your biggest concern about termite control costs?
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
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.

Questions people ask
Why do termite quotes vary so much?
Drilling through concrete adds labor. Compare what's included, line by line. Companies measure differently and use different products. Some include a warranty or yearly checks.
How much does termite fumigation cost?

How much does a termite inspection cost?

How long do termite bait stations take to work?
Termites have to find the stations first. Then the bait spreads through the colony. Usually several weeks to a few months.
Can termites damage a house on a concrete slab?
They come up through expansion joints, plumbing gaps and small cracks. Inspectors check those spots first. Yes.
Do I have to leave my house during termite treatment?
Fumigation is different. Everyone leaves for two to three days, pets and houseplants included. Not for a soil treatment or bait stations.
Can I treat termites myself instead of hiring a professional?
Around Keizer, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Around Keizer, 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 Keizer, the usual culprit is the western subterranean termite.
