Carpenter Ant Exterminator Seattle WA

Seattle's abundant moisture and wood-frame construction make our area a prime target for carpenter ant infestations. These large black or dark brown ants are attracted to damp, decaying wood and can establish satellite colonies throughout a structure. By the time you see them inside your home, the colony may have been active for months or even years.

Signs of a carpenter ant infestation include seeing large winged ants (swarmers) indoors, finding small piles of sawdust-like frass near baseboards or window frames, hearing faint rustling sounds inside walls, and noticing structural damage around windows, doors, or areas with moisture issues.

Our carpenter ant extermination process is thorough and targeted. We begin with a comprehensive inspection to locate the main colony and any satellite nests. Carpenter ants often nest in multiple locations — inside walls, in attic insulation, behind siding, in dead trees, and in landscape timbers. Missing even one nest can allow the infestation to continue.

Treatment involves a combination of targeted baiting systems, residual insecticides applied to nest sites and foraging trails, and exterior perimeter treatments. We use products specifically formulated for carpenter ant biology, ensuring the treatment reaches the queen and eliminates the colony at its source.

Because carpenter ants are attracted to moisture, addressing water issues is critical for long-term control. We'll identify moisture problems — leaking pipes, poor drainage, inadequate ventilation — and recommend repairs that make your home less attractive to future infestations.
