Are These Carpenter Ants? A Seattle Homeowner’s Identification Guide
Correct identification is critical. Mistaking carpenter ants for other species can lead to ineffective treatment and ongoing damage.
| Trait | Carpenter Ant | Common Look-Alike (Moisture Ant) |
|---|---|---|
| Size | Large (1/4″ to 1/2″) | Similar size |
| Color | Typically solid black, or red-black | Yellowish to dark brown |
| Waist | Single, rounded node | Varies |
| Key Sign | Frass: Piles of fine wood shavings mixed with dead insect parts, often found near baseboards or windowsills. | Habitat: Found only in severely decayed, wet wood. Their presence is a major red flag for a moisture problem. |

The Carpenter Ant Threat to Seattle Homes
They Excavate Wood, They Don’t Eat It.
Unlike termites, carpenter ants don’t consume wood for nutrition. Instead, they excavate smooth, clean galleries inside it to build their nests. This tunneling weakens structural timbers, window frames, roof eaves, and decks from the inside out, often with little visible damage until it’s significant.
Why Your Seattle Home is a Prime Target
Our local climate and architecture create the perfect storm:
- Leaky Roofs & Siding: Seattle’s persistent rain can lead to moisture intrusion in vulnerable spots of your home.
- Damp Crawl Spaces & Basements: Poor ventilation common in older homes creates ideal, humid nesting conditions.
- Aging Wood: The beautiful cedar siding and timbers on Ballard Craftsman or Queen Anne Victorians become more susceptible with age.
- Wood Soil Contact: Decks, stair rails, or landscape timbers touching damp soil provide a direct highway inside.
If you suspect moisture issues, our moisture and pest damage inspections are designed to find the source.
Our 3 Step Carpenter Ant Elimination Process for Seattle Homes
We don’t just spray. We perform colony level surgery to eliminate the threat and prevent its return.
Step 1: The Forensic Moisture & Nest Hunt
Our certified technician conducts a detective like inspection:
- Using moisture meters and thermal imaging to locate damp wood behind walls and under floors.
- “Sounding” wood to detect hollowed out galleries.
- Tracking foraging trails (often at night) to pinpoint nest locations.
- Thoroughly inspecting attics, crawl spaces, and exterior perimeters.
Step 2: Targeted Nest Elimination
Using professional grade methods unavailable to consumers:
- Direct Nest Treatment: Applying non-repellent insecticides and dusts directly into wall voids, attic spaces, and nest galleries to ensure the queen is eliminated.
- Strategic Baiting: For satellite colonies, we use specialized baits that workers carry back to the heart of the nest.
- Crucially: We identify the moisture leak (like a faulty seal or gutter) that caused the rot, so the problem doesn’t recur. This is the core of our guaranteed process.
Step 3: Exclusion & Follow Up Protection
Killing the colony is only half the job. We ensure long term protection by:
- Sealing identified entry points with appropriate, long lasting materials.
- Recommending fixes like trimming tree limbs away from the roof, improving crawl space ventilation, and diverting downspout water.
- Scheduling a mandatory follow up visit to guarantee the colony is eradicated, backed by our service warranty.
Local Case Study: Carpenter Ant Removal in a Queen Anne Craftsman
The Problem: A homeowner noticed small piles of “sawdust” (frass) in a second-floor bathroom and saw a few large black ants at night.
Our Inspection: An AMPM Exterminators technician used a moisture meter on the exterior wall, discovering high dampness around a window. The trail led to a satellite nest inside the wall, originating from a parent colony in a rotting fence post in the backyard.
The Solution: We treated the indoor nest directly, eradicated the outdoor colony, and sealed the entry point at the window frame. We also referred a contractor to repair the failed window seal the true moisture source.
The Result: Complete elimination. The homeowner has been ant free for over two years and uses us for annual preventative maintenance.
Carpenter Ant Control FAQ for Seattle Homeowners
Q: I see big ants only in spring. Is it an issue?
A: Yes! In Seattle, spring is swarmer (winged reproductive ant) season. Seeing swarmers indoors almost always means an established nest is inside your structure. This is a critical sign to call a pro immediately.
Q: Can’t I just spray the ants I see with store bought spray?
A: This is the #1 mistake. Spraying repellents scatters the colony, causing it to split and create multiple hidden satellite nests. This “bounce effect” makes the problem far worse and more expensive to fix. Learn more about why DIY fails.
Q: Is carpenter ant damage covered by homeowners insurance?
A: Typically, no. Most policies classify insect infestation as a maintenance issue, not sudden “damage.” The most cost-effective solution is early professional treatment to prevent extensive damage. View our transparent pricing guide.
Q: How are you different from other Seattle exterminators?
A: We specialize in forensic pest control. For carpenter ants, we don’t stop at killing the insects. We are trained to find and help you fix the moisture problem that attracted them, providing a permanent solution, not a temporary fix. This is part of our hyper localized process used across King County.
