Ant Control in Oregon and Washington
Don't Let Ants Take Over Your Kitchen or Your Crawlspace
Ant control starts with knowing which ant you have. Odorous house ants, carpenter ants, pavement ants and moisture ants each nest in different places and respond to different treatments. A&A inspects the property, treats the exterior with a non-repellent perimeter product, places bait where ants are foraging, and returns if activity continues.

How do I get rid of ants?
The ants you see are a small part of the colony. Workers forage for food and moisture while the queens and brood stay hidden in the nest, so wiping up a trail or spraying a few workers leaves the source untouched. Effective ant control treats the colony through the ants themselves, and the steps below are how an A&A technician does it:
Step 1 of 5 shown
-
Comprehensive inspection
Your technician identifies the species, finds where the ants are active, and checks what is feeding them and which conditions, such as moisture, debris or vegetation touching the structure, are drawing them in.
-
Exterior perimeter treatment
A non-repellent, transferable product goes along the foundation and out a couple of feet from it. Ants cross it without noticing and carry it back to the colony, which is how the treatment reaches the nest.
-
Targeted interior baiting
Bait placed where ants are foraging inside keeps the work focused and low-disruption, and you do not need to leave your home or business. If the species or the nest calls for it, treatment can also go into wall voids and other harborage areas.
-
Give the bait time to work
You may notice more ants initially as bait attracts foraging ants. Leave the bait undisturbed and avoid cleaning around it so ants can carry it back to the colony. Results usually show within a few days, but full control may take several weeks.
-
Follow-up and prevention
If activity continues, we return within the warranty period with additional methods. Ants reinfest from neighboring properties and follow old pheromone trails, so a recurring program with routine inspections keeps them from re-establishing.
Are ants harmful?
Most ants are a nuisance, but not all of them. At a minimum, ants contaminate food and keep coming back along the trails they lay down. Carpenter ants and moisture ants are different: carpenter ants excavate wood, and their damage can stay hidden inside walls, beams and crawlspaces, while moisture ants tunnel in already-rotting wood and signal a moisture or decay problem. The problem is worth treating early, because ants rebuild quickly after a partial treatment.
-
Odorous house ants contaminate food and give off a rotten-coconut smell when crushed.
-
Pavement ants work their way into kitchens and pantries from slabs and foundations.
-
Carpenter ants tunnel through structural wood to build nests.
-
Moisture ants nest in water-damaged wood and signal a leak or drainage problem.
-
Colonies rebuild after partial treatments, so activity can return within weeks.

Which ants are common in Oregon and Washington?
Four species cause most of the ant calls A&A takes at Northwest homes and businesses. They look similar to the untrained eye, but where they nest, what they feed on and how they respond to treatment are not alike, so identification comes first.
Thatching ants, which build mounds of fir and pine needles that can reach three to four feet high, are treated at the mound when it sits on your property. When the mound is next door, the technician plans around it.
-
Odorous house ants
Often called sugar ants, they release a rotten-coconut smell when crushed. A colony can hold several queens and splits into smaller colonies when disturbed, which is why sprays and cleaners often scatter the problem instead of ending it. They nest almost anywhere, from leaf litter outdoors to wall insulation and kitchen cabinets.
-
Carpenter ants
Large black or red-and-black ants that tunnel through wood without eating it. The parent nest is usually outdoors in a stump, log or other damp wood, and a satellite nest can form inside a structure. Sawdust-like frass pushed out of small cracks marks the nest and is the most reliable sign.
-
Pavement ants
Common along driveways, sidewalks and between pavers, where they leave small piles of sand and soil. They are about the size of odorous house ants but have two nodes between the thorax and abdomen and a squarer head, and they get into kitchens most often on slab foundations.
-
Moisture ants
They live in heavily water-damaged wood and feed on the fungus that decay produces, leaving galleries that look like a sea sponge. Winged reproductives often appear in late summer. They need constant moisture, so fixing the leak or drainage problem matters as much as treatment.
Ant prevention tips
Ants follow food, water and shelter. These five steps take away what draws them in:
-
Keep food and crumbs contained
Wipe down counters, clean up spills and grease, and store pet food and pantry items in sealed containers.
-
Fix moisture problems
Repair leaks, ventilate bathrooms and basements, and clear standing water from crawlspaces. Moisture ants and carpenter ants both go for damp, decaying wood.
-
Cut the bridges
Trim trees, shrubs and plants back from the building so they cannot carry ants straight to the siding or roof.
-
Clear debris from the foundation
Move firewood, stumps, mulch piles and clutter away from the structure, where ants like to nest.
-
Skip the store-bought sprays
Cleaners and over-the-counter sprays can split an odorous house ant colony into several. Call us and let the bait do its work.
FAQs
Why do I see more ants after treatment?
More activity in the first few days is normal as the bait attracts foraging ants. Ants carry it back to the nest, and that traffic must happen for the colony to be affected. Most people see results within a few days, but full control may take several weeks. If activity persists, we will return within the warranty period at no additional cost, utilizing additional treatment methods if necessary.
Why do ants keep coming back after I spray them?
Sprays kill the workers you see, not the nest. Oregon State University Extension notes that fast-acting insecticides can cause an odorous house ant nest to fracture into several, so the problem spreads instead of ending. Ants also follow existing pheromone trails and reinfest from neighboring properties, which is why prevention matters after treatment.
How can I tell carpenter ants from other ants?
Carpenter ants are larger than most household ants, black or red and black, and leave piles of sawdust-like frass near their nest. They tunnel through wood without eating it, which separates them from termites. Frass below a wall, window frame or beam is a good reason to have a technician inspect.
How much does ant control cost?
It depends on the size of the property and the extent of the problem, and pricing stays transparent with no hidden fees. For homes, our office team provides free estimates over the phone. We provide a complimentary site inspection for any multi-family or commercial property seeking a bid on recurring services.
How fast can a technician get here?

Does A&A offer recurring pest control plans?
Yes, we offer recurring pest control programs designed to provide year-round protection against common Northwest pests. Service frequency is customized based on your property, pest pressures, and individual needs, with options ranging from monthly to quarterly visits. Recurring service helps prevent problems before they become infestations while providing ongoing peace of mind.
