Why Willamette Valley homes see the pests they do
Salem sits in the middle of the Willamette Valley, with wet winters, mild springs and dry summers. Ants and rodents stay active most of the year, yellow jacket nests grow all summer, and the first fall rains push spiders, boxelder bugs and mice toward the house.
The valley around the city is farm country. The USDA’s 2022 Census of Agriculture ranks Marion County first among Oregon counties for farm sales. Fields, orchards and nurseries sit a short drive from most Salem neighborhoods, and the pests that live on that open ground find their way to the edges of town.
It wears on you. You check under the sink, you buy another can of spray, you wonder whether the noise under the floor is a rat or the house settling.
With a plan, that job is ours. Your technician treats before each pest’s season starts, and if something gets through between visits, one call brings us back, included in your plan.
Common Salem pest problems and what we do about them
These are the calls our Salem office takes most. Each one starts with an inspection, because the right fix depends on what is actually there.
When rats or mice get into the crawl space
Most Salem homes we inspect have a crawl space, and that is where rodents usually set up. Torn vent screens, gaps around pipes and a stack of stored boxes are enough. Marion County Environmental Health advises sealing openings, keeping garbage in closed containers and storing food in sealed containers. We do the inspection, set traps and locked bait stations, and quote sealing for the gaps we find.
Rodent control in Salem →When ants trail across the kitchen in spring
OSU Extension calls odorous house ants the most common house-infesting ants in western Oregon. They are small and dark, smell like rotten coconut when crushed, and show up after heavy rain or hot spells. Big black ants and little piles of sawdust point to carpenter ants instead, which need a different treatment.
Ant control in Salem →When the webs come back every September
The Oregon Department of Agriculture says giant house spiders and hobo spiders are introduced from Europe, that neither species is considered harmful, and that the males are usually seen in late summer and fall while they look for mates. That is the spider you meet in the hallway. We sweep webs and egg sacs at each exterior visit and treat where spiders and their insect food gather.
Spider control in Salem →When yellow jackets nest in the lawn or the wall
The PNW Insect Management Handbook says a yellow jacket colony starts with one queen in spring, can hold thousands of workers by late summer, and is most troublesome in August and September. Nests can be in the ground, in the open or inside a wall void. Leave the entrance alone and call us. Our technicians treat nests with protective gear.
Wasp control in Salem →When bugs cover the south wall in the fall
OSU Extension says boxelder bugs can gather by the thousands on south and west walls in fall looking for winter shelter, along with brown marmorated stink bugs and other fall invaders. They do not breed indoors. Sealing gaps, repairing screens and clearing debris from the foundation is the first fix, and treating the walls where they gather before the fall run cuts the numbers down.
Boxelder bug guide →When you need a termite or WDO inspection
OSU names the Pacific dampwood termite and the western subterranean termite as the two termites that damage buildings in the Pacific Northwest. Dampwood termites need moist, water-damaged wood, and OSU notes that treatment will not hold unless the moisture is fixed. We inspect homes for buyers, sellers and owners and quote treatment after the inspection.

Local Context: Salem and the Willamette Valley
Salem notices yellow jackets in September. Our calls come in July and August.
iNaturalist records for Marion and Polk counties over the last five years show 28% of the year’s verifiable yellow jacket sightings in September, more than any other month. Interstate Pest Management records for new Oregon customers over the same five years put the peak a month or two earlier: July and August brought 47% of the year’s new wasp and yellow jacket calls. By the time yellow jackets are at the picnic table, the nest has been growing all summer.
The same pattern runs through the year. Carpenter ant sightings in Marion and Polk counties bunch into March through June (78% of the year), and new ant calls to our Oregon offices peak in March at 19%. Giant house spider sightings land in August and September (50% of the year), right on top of our September spider peak. Rats and mice stay on the calendar all year: every month brought at least 6% of new rodent calls, and September through December brought 39%.
Salem is our newest office, so the calendar below comes from our Oregon customers over the last five years, most of them in the Portland area up the valley. Our Salem visits so far follow the same lead: rats and mice have come up on more Salem visits in 2026 than any other pest.
Be ready before March. Start a plan now and your first visits land ahead of the spring ant surge, with re-services included as needed between visits.

What Marion and Polk County neighbors log most
iNaturalist is a public site where people post photos of the insects and spiders they find, and experts confirm the ID. Boxelder bugs top this list for Marion and Polk counties over the last five years, with 702 verifiable sightings. March is the busiest month, when the bugs that spent the winter in walls and attics come back out.
Brown marmorated stink bug sightings peak in October, when they look for a way into the house for the winter. OSU Extension lists them with boxelder bugs as fall invaders that do not breed indoors. Sealing gaps around windows, doors and the foundation before October keeps most of them out.
| Insect or spider | Sightings | Peak month |
|---|---|---|
| Boxelder bugs | 702 | March |
| Giant house spiders | 158 | September |
| Carpenter ants | 150 | May |
| Odorous house ants | 136 | June |
| Yellow jackets | 122 | September |
| Brown marmorated stink bugs | 166 | October |
Invasive insects being watched in Salem
State agencies keep traps out across Salem, and a few finds have made the news. In August 2026 the Oregon Department of Forestry confirmed emerald ash borer, a beetle that kills ash trees, inside Salem city limits for the first time. It is a tree pest, not a house pest, and we don’t treat trees. Report suspected ash borer damage to the Oregon Invasive Species Hotline at 1-866-INVADER, and don’t move ash or other hardwood firewood out of the quarantined counties, which include Marion.
The Oregon Department of Agriculture found a single Japanese beetle in Salem in 2025 and no more in follow-up surveys. Salem, Keizer and Woodburn are not treatment areas. ODA also caught one spongy moth in Salem in 2025 and plans more survey work in the area in 2026, with no treatment planned. If you find an ODA monitoring device in your yard, leave it in place.
What our customers say
4.96 average from 8,394 Google reviews
“The tech called ahead, showed up right on time, let me know what he was doing, then went about his task and shut and latched the back gate when done. Nice job!”
“Thankful for our preventative pest control subscription! The inspectors are always very kind and answer any questions we may have. Highly recommend”
“Caleb came out and was absolutely professional, kind and helpful. He explained his steps and was very thorough. Thank you!”
Serving Salem, Keizer and the mid-Willamette Valley
Same team, same plans and same re-service promise across Salem, including South Salem, Northeast Salem and West Salem on the Polk County side of the river, plus Keizer, Aurora, Woodburn and Hubbard. Older homes near downtown tend to have crawl spaces and vents that let rodents in. Wooded lots in the South Salem hills come with firewood stacks and stumps, which OSU names among the places carpenter ants nest outdoors.
Salem pest control questions
Still deciding? Our Salem office answers the phone Monday to Friday, 8am to 5pm.
How much does pest control cost in Salem?
The All Seasons Pest Service is $39/mo with a $260 one-time setup fee. The All Seasons Rodent Service is $39/mo with a $280 setup fee, and the All Seasons Pest & Rodent Service is $47/mo with a $280 setup fee. The One-time Rodent Service is $350 for the first visit, then $60 per follow-up. Exclusion work is quoted separately.
When is pest season in Salem?
In Interstate Pest Management records for new Oregon customers over the last five years, ant calls peaked in March, wasp and yellow jacket calls in July and August, and spider calls in September. Rodent calls come in all year and rise from September through December.
Why do I see so many spiders in the house in September?
The Oregon Department of Agriculture says male giant house spiders and hobo spiders wander in late summer and fall looking for mates, and that neither species is considered harmful. In iNaturalist records for Marion and Polk counties over the last five years, 50% of giant house spider sightings came in August and September.
What are the bugs covering my south wall?
In fall it is usually boxelder bugs or brown marmorated stink bugs looking for winter shelter. OSU Extension says they gather on sunny south and west walls and do not breed indoors. Sealing gaps keeps most of them out, and our plan covers treating the walls where they gather.
What if pests come back between visits?
Call us. Re-service between scheduled visits is included on every All Seasons plan.
How fast will someone get back to me?
Quote requests sent before 4pm, Monday to Friday, get a call back from our Salem office the same day.
Where can I get a garden pest identified?
For plant and garden pests, the OSU Extension Master Gardener help desk for Marion County is at 1320 Capitol St. NE in Salem, 503-373-3770, and takes questions with photos. For anything in or on the house, send us a photo and we will tell you what it is.
Do you treat mosquitoes?
Mosquitoes are a rare request for us. The Oregon Health Authority’s 2025 West Nile virus map shows no positives in Marion or Polk counties. Emptying standing water in buckets, gutters and plant saucers each week does more than spraying.
Is there anything you don’t treat?
Ticks, moles, voles, wildlife and tree pests like emerald ash borer are outside what we do. Call anyway and we’ll suggest where to start.
