Bait treatment
Workers carry bait to the nest, which can end a colony that spray never reaches. Patience matters: killing the trail too fast can stop the bait from being carried. The technician may ask you not to wipe or spray bait stations.

Ant Control
Ant Control: what it covers
Quick answer
Ant control in Seattle starts with identifying the ant, because the right bait depends on the species and on whether it is a trail-forming kitchen ant or a wood-nesting carpenter or moisture ant. A technician follows the trail to the nest and entry point. Seattle Pest Control connects King County callers with an independent local company.
Not all ants need the same answer. A line of tiny ants crossing a counter is usually a trail-forming species coming for sweets or grease. Larger black ants in a bathroom at night may be carpenter ants from a damp sill. Small pale ants in a rotted board may be moisture ants. Treating them alike is how people spend money and still see ants. Species claims on this page are deliberately general: odorous house ants and pavement ants are the sort of kitchen and foundation ants a technician may find, and the technician names what you have.
The weather turning is often what prompts the call. When rain arrives after a dry spell, ants move indoors; when lawns dry out in summer, a leaking pipe or a pet bowl becomes the nearest water. Seattle Pest Control is a call line, answered 24/7, that connects you with an independent local pest-control company, and a same-day visit is offered only when a technician is free. This page covers everyday ants; for wood-nesting species see carpenter ant control and moisture ant control.

Warning signs
Signs you need ant control
Do not use foggers or spray ant bait stations, and keep bait out of reach of children and pets. Do not apply garden pesticides indoors, and follow every product label.
- A visible trail of small ants between a crack and a food source, such as a sink, a pet bowl or a crumb
- Ants returning the morning after you wipe the counter
- Ant mounds or small piles of soil along a patio edge, a driveway crack or the base of a foundation
- A sweet or rotten-coconut smell when ants are crushed, which can point to a particular species
- Ants around plumbing, a dishwasher, a bathtub or a house plant
- Winged ants gathering at a window, which can be a seasonal swarm
- Ants emerging from an outlet, a baseboard or a crack in the wall
- Ants on a deck rail, a fruit tree or a hose bib in warm weather
Our process
How our ant control visit works
Tell us what they look like
Describe size, color, where you see them and what they are after. A photo or a captured specimen helps. A same-day visit is offered only when a technician is free, and no arrival time is promised.
Identify the ant
The technician checks size, color, waist shape and behavior. The answer decides whether this is a bait job, a moisture problem or a case for a wood-nesting ant service.
Follow the trail
Ants travel regular lines. The technician follows one inside and outside to find the entry crack and, where possible, the nest. Looking for the nest beats treating the trail alone.
Check what is attracting them
Food, moisture and plants touching the house are noted. Honeydew-producing insects on shrubs can feed ants, and a dripping fixture can supply the water.
Agree the price, then bait
The price is confirmed with you before work. Baits are placed along trails and entry points, and perimeter treatment may be added. Labels are followed and children and pets kept away.
Seal and re-check
Cracks around windows, pipes and foundations are noted for sealing. A return visit confirms that trails have stopped, and you are told which habits keep them away.
Cost
How much does ant control cost in Seattle?
No outside price for Seattle ant control is printed here. What changes a quote is below.
| Job | Typical range | What it includes |
|---|---|---|
| Which ant | Varies | A kitchen trail and a wood-nesting colony are different jobs |
| Indoor and outdoor work | Varies | Perimeter and nest treatment add to a baiting visit |
| Number of visits | One or several | Ant colonies often need a return check |
| Size of the property | Scales with the space | A large lot with many foundation cracks takes longer |
| Moisture or sealing | Quoted separately | Repairing a leak or sealing gaps is not part of the ant treatment |
Your exact price is confirmed on site before work starts. See the Seattle cost guide for what moves a quote.
Why do ants come inside when the weather changes?
They look for food, water and shelter. Heavy rain floods nests and pushes ants toward drier buildings, while dry spells send them toward leaks and sinks. Either change can bring a trail across the kitchen. The cause is rarely dirt; a few crumbs or a damp spot is enough to start a trail.
Scout ants find a resource and lay a scent trail, and others follow. Wiping the counter removes the food, but the trail may remain, which is why ants can come back in the morning.
Keeping sweet and greasy food in sealed containers, drying sinks and fixing drips takes away the draw. Those habits help with any ant species.
Is spraying a good way to deal with ants?
Spraying kills the ants you see but rarely the colony, and it can scatter them into new areas. Bait carried back to the nest is usually more effective. Over-the-counter sprays also leave residue where children and pets touch. A technician tells you whether spray has any place in your case.
If you spray, you may break the trail the technician needs to follow. If you must act before the visit, wipe with soapy water and store food securely, then wait.
Bait is slow by design. Seeing more ants at first can be a sign that the bait is working, as they come to feed and carry it away.
How do I tell a harmless ant from a damaging one?
Size, color and where they appear give clues. Large, dark ants emerging at night from a wall or sill may be carpenter ants, which excavate wood, according to WSU. Small, pale yellowish-brown ants in damp wood may be moisture ants. Tiny trail-forming ants in the kitchen are usually a nuisance, not a structural threat.
The location is the strongest hint. Ants in food areas are usually foragers. Ants coming from a window frame, a damp board or a crawl space suggest nesting in the structure.
If you are unsure, catch one and call. A technician can identify it by shape and size, and you avoid the wrong remedy.
- Large and black: possibly carpenter ants
- Small and yellowish-brown in damp wood: possibly moisture ants
- Tiny and trailing across food: a foraging species
- Winged and many at once: a swarm; identify before acting
What can I do to keep ants out?
Seal food in containers, fix leaks, trim shrubs and branches back from the house, remove stumps and logs near the foundation and caulk cracks around windows and pipes. These steps reduce food, water and shelter. They help with all species but do not remove an existing colony.
Mulch piled against siding gives ants a bridge and a damp nest site. Keeping it a few inches back helps both ant control and wood health.
Check pet bowls, bird feeders and compost. Ants find them quickly.
Options
Types and options for ant control
Perimeter treatment
A treated band around the foundation and entry points reduces ants coming in. It works alongside, not instead of, bait and sealing, and weather can shorten its effect.
Nest treatment
When the nest is found in soil, a mound or a void, it is treated directly. This is quicker than relying on bait alone, but needs the nest to be found.
Handing off to a wood-ant service
If the ants prove to be carpenter or moisture ants, the case moves to a service built for them, because damp or decayed wood is part of the problem.
King County
Why ant control is different in Puget Sound
Seattle weather swings between months of rain and a comparatively dry summer, and ants respond to both. The wet season, roughly October to March, can drive nests out of saturated soil, and the dry months push ants toward kitchens, sprinkler heads and leaks. Neither pattern is a promise, only a tendency worth knowing.
Spring brings the larger carpenter ant swarms, which WSU gives as April to early June, and homeowners often notice winged ants then. A swarm on a window sill needs identification, because winged termites can look alike to the untrained eye.
Older houses and apartments with settled foundations, aged window frames and gaps around pipes offer more routes in than tight new construction. Gardens and mature trees across Seattle, Kirkland, Redmond and the other Eastside suburbs add honeydew and shade that ants like. Condo and apartment residents should tell management, since ants travel along shared walls.
One call and it gets handled.
Most ant control calls are scheduled the same day when a technician is free, and you approve the price before any work starts.

FAQ
Ant Control FAQs
Why do ants return after I clean?
Cleaning removes crumbs but not the scent trail or the nest. Ants may come back until the colony is dealt with or the entry is sealed.
Is bait safe around pets?
Bait is placed in small amounts, often in stations, and the label is followed. Tell the technician about pets and children so placement keeps them out of reach.
How long until the ants are gone?
No timeline is promised. Bait can take days to weeks, and a return visit checks results.
Do ants mean I have a wood problem?
Not always. Kitchen ants are usually after food. Ants coming from a wall or damp wood point to a nest in the structure and call for a closer look.
Can I treat outdoors only?
Sometimes, if the ants are not coming inside yet. A perimeter treatment can help, but it works best with sealing and removing attractants.
What if I see winged ants?
Capture one and call. Winged ants and winged termites can look alike, and the answer decides the next step. See termite inspection if a termite is possible.
