Signs of an ant problem in a Salem home
A few ants after a warm rain are normal. These signs mean a colony has moved in.
Trails after rain
Lines of ants on counters and window sills that show up after heavy rain or a hot spell.
A rotten coconut smell
Odorous house ants give off that smell when crushed, which is how you tell them apart.
Sawdust piles
Coarse wood shavings under window frames, decks or in the crawl space point to carpenter ants.
Winged ants indoors
Large winged ants inside in late winter or spring can mean a carpenter ant nest in the house.
Why ants show up early in the Willamette Valley
In Interstate Pest Management records for new Oregon customers over the last five years, ants were on 31% of first visits, and March brought 19% of the year’s new ant calls, more than any other month. OSU Extension calls odorous house ants the most common house-infesting ants in western Oregon, and says invasions follow very hot or cold weather, heavy rain and food left out.
Carpenter ants are the other big one. OSU’s carpenter ant guide calls them serious pests of buildings in Oregon, especially west of the Cascades, and says they prefer moist, rotting wood. In iNaturalist records for Marion and Polk counties over the last five years, 78% of carpenter ant sightings came March through June.
How we handle ants in Salem
- 1
Identify the ant
Your technician follows the trails, checks nesting spots and looks for moisture to confirm which ant you have.
- 2
Treat the nest, not the trail
We place baits the workers carry home, so the treatment reaches the queen and the nest you can’t see. For carpenter ants we find the wet wood they are using and show you what to fix.
- 3
Get ahead of March
Your scheduled visits land before the spring ant surge. If a trail shows up between visits, re-service is included in your plan.

What waiting costs
- Ants that find food once keep coming back to it, and so does the trail.
- Carpenter ants keep hollowing out wood as long as the nest is there.
- The moisture that drew carpenter ants in keeps softening the wood around it.
What it looks like when ants are handled
A clean counter after a rainy week, a bathroom without a trail to the sink and a spring you don’t spend chasing ants.

When ants send Oregon homeowners to the phone
Our records show the month each new Oregon customer first called us about ants. Salem is our newest office, so these five years of records come mostly from the Portland area up the valley, on the same Willamette Valley seasons. Your plan visits are set ahead of those months, so ants find a treated house when they arrive.

How much does ant control cost in Salem?
Ants are covered by the All Seasons Pest Service at $39/mo with a $260 one-time setup fee. If you also need rats and mice covered, the All Seasons Pest & Rodent Service is $47/mo with a $280 setup fee.
When is ant season in Salem?
In Interstate Pest Management records for new Oregon customers over the last five years, new ant calls peaked in March, and 55% arrived March through June.
What are sugar ants?
Most small ants people call sugar ants in Salem homes turn out to be odorous house ants. They are about 1/8 inch, dark brown or black, and smell like rotten coconut when crushed.
How do I know if I have carpenter ants?
Look for large black ants indoors, winged ants in late winter or spring, and coarse sawdust under a window, deck board or in the crawl space. We confirm the species before treating.
Why do ants keep coming back after I spray?
Spray only reaches the ants on the counter, and the nest behind the wall keeps sending more. Baits the workers carry home reach the nest. If ants come back between scheduled visits, re-service is included in your plan.
Is treatment okay with kids and pets at home?
We use an Integrated Pest Management approach: baits and targeted treatments instead of blanket spraying. Your technician tells you where each bait or treatment went and when kids and pets can be back in that area.
