Why Professional Treatment
Seattle Ant Problems Aren’t Solved with a Can of Spray
Ants are the most common nuisance pest in the Seattle area and the most misunderstood. Over the counter repellents can actually make infestations worse: odorous house ants, for example, will split their colony when threatened, multiplying your problem two or three times over.
Important: Carpenter Ants vs. Sugar Ants
Not all ants are the same. Carpenter ants burrow through wood and can cause significant structural damage over time. Moisture ants are typically a sign of underlying water damage. A professional inspection identifies the species and the right treatment before damage compounds.
AMPM Exterminators technicians are trained to identify every ant species common to the Pacific Northwest, assess the full scope of the colony (including nests hidden inside walls or on neighboring properties), and apply targeted treatments that eliminate the source not just the scouts.

Species We Treat
Common Ant Species in the Seattle & Puget Sound Region
Successful ant control starts with correct identification. Here are the most common species our technicians treat throughout the greater Seattle area.
Carpenter Ants – Structural Risk
Large black or reddish-black ants (6–13mm) that tunnel through moist or damaged wood. They don’t eat wood, but their galleries weaken structure over time. Multiple nest sites inside walls and in nearby stumps or trees make professional treatment essential.
Odorous House Ants – Nuisance
The classic “sugar ant” small, dark brown to black, and notorious for the rotten coconut odor released when crushed. They form massive colonies and follow pheromone trails directly to your kitchen. Spray repellents cause colony splitting; bait based treatment is required.
Moisture Ants – Structural Risk
Small yellow ants that target wet or decaying wood. Their presence is often a warning sign of deeper water damage inside walls or under floors. Treatment must address both the ants and the underlying moisture source.
Argentine Ants – Nuisance
Tiny, fast reproducing ants originating in South America. Ants form enormous super colonies and are highly social spotting one means many thousands more are nearby. They spread rapidly and can displace native ant species.
Pavement Ants – Nuisance
Found nesting under sidewalks, patios, and driveways. When they invade your kitchen or patio entertaining area, they become a persistent nuisance. Nests are deep and require targeted exterior perimeter treatment.
Pharaoh Ants – Hard to Eliminate
Light colored micro ants that form enormous colonies with multiple queens. They’re highly resistant to many treatments when threatened, they “bud” into several smaller colonies. Professional baiting strategies are the only effective approach.
European Fire Ants – Stinging
Red, stinging ants spreading from British Columbia into the Seattle area. Their bites are painful and they can be aggressive when disturbed. A growing concern for homeowners with gardens and outdoor spaces.
Thatching Ants – Biting
Red and black ants found in forested and suburban areas. They build distinctive straw covered mounds in the ground and can deliver a painful bite. Common in wooded yards throughout the Puget Sound region.

How We Work
Our Ant Control Process
Effective ant extermination is more than spraying a perimeter. Our multi step process targets the colony at its source.
- Identify the Species Control measures differ by species. Correct identification is the foundation of every treatment plan misidentifying ants is how DIY attempts backfire. Learn about our inspection process →
- Inspect Inside & Out We check for entry points, pheromone trails, moisture damage, and nest sites including hard to reach areas like wall cavities, crawl spaces, and under foliage.
- Destroy Nests & Trails Visible nests and active trails are eliminated. For ants inside walls, we use targeted injection techniques rather than broad applications that scatter colonies.
- Perimeter Treatment We apply a non repellent, water based solution to the full exterior perimeter. Ants carry it back to the nest on the tiny hairs of their legs, spreading it throughout the colony.
- Strategic Baiting Where needed, baits are placed in locations that maximize colony kill while keeping them away from pets and children the correct solution for pharaoh ants and odorous house ants.
- Prevention Recommendations We’ll identify attractants on your property and recommend practical changes that reduce the likelihood of re-infestation the most eco friendly control of all.
Prevention
What You Can Do Between Treatments
- Store all food including pet food in airtight containers.
- Wipe down countertops daily to remove crumbs and disrupt pheromone trails.
- Create a moat (a pie tin with soapy water) around pet food bowls.
- Inspect your home periodically for damp, soft, or decaying wood.
- Trim vegetation so plants are at least 12 inches from the foundation.
- Seal cracks and gaps around windows, doors, and utility entry points.
- If you crush an ant and it smells like coconut or rotting fruit, it’s an odorous house ant call us before the colony splits.
Treatment Safety
Safe for Your Family & Pets
Our non repellent, water based treatments are designed to affect only insects. Because insects and mammals have fundamentally different digestive systems, our solutions are not harmful to humans or animals.
Baits are placed in strategic, out of reach locations and are odorless, so ants can’t detect and avoid them which is what makes them effective.
For customers with young children, infants, or multiple pets, let your technician know and we’ll discuss additional precautions tailored to your household.

Common Questions
Frequently Asked Questions About Ant Control in Seattle
Get the answers homeowners most often ask before booking their first ant treatment.
What types of ants are common in Seattle and the Puget Sound?
The most common species in our area include odorous house ants (also called sugar ants), carpenter ants, moisture ants, Argentine ants, pavement ants, pharaoh ants, thatching ants, and the increasingly prevalent European fire ant. Each species has different behaviors, nesting habits, and requires a distinct treatment approach. That’s why correct identification by a trained technician is the critical first step.
Why are ant infestations so difficult to control on your own?
Most store bought sprays are repellent based. When ants encounter a repellent barrier, they don’t die Ants turn around and find a new way in. Worse, some species like odorous house ants respond to repellents by splitting their colony into multiple new colonies. You end up with three ant problems instead of one. Professional treatments use non repellent products that ants unknowingly carry back to the nest, eliminating the colony at the source. Read our full guide →
How do I know if I have carpenter ants vs. regular house ants?
Carpenter ants are much larger (6–13mm) and typically black or reddish black. They nest in wood and you may see frass sawdust-like material mixed with insect parts near baseboards or window frames. “Regular” house ants like odorous house ants are small (2–4mm) and attracted to sweets. But visual identification can be tricky; our technicians provide a definitive ID during inspection. Learn more about carpenter ants →
Are ant treatments safe around children and pets?
Yes. Our water based, non repellent treatments are formulated to target insects only. Mammals and insects have fundamentally different digestive systems, so these products are not harmful to humans or pets. Baits are placed in strategic, out of reach locations. For households with infants, crawling children, or multiple pets, let your technician know and we’ll add extra precautions tailored to your home. See our safety guarantee →
Do you offer same day or next day ant control service?
Yes. We maintain same day and next day availability throughout the greater Seattle area. Call (206) 571 7580 in the morning and we can often have a technician out that afternoon.
How many treatments will I need?
Most common ant infestations are resolved in one to two treatments. The first visit eliminates the active colony and establishes a perimeter barrier. A follow up visit two to three weeks later ensures no satellite colonies remain. Carpenter ants or pharaoh ants may require additional targeted treatments due to their complex nesting habits.

Pricing depends on the size of your home, the species of ant, and the severity of the infestation. Most residential ant treatments range from $150 to $300. We provide free, no obligation quotes before any work begins call (206) 571 7580 for an estimate tailored to your home. See our pricing page →
Do you treat carpenter ants?
