Carpenter Ants in Seattle Homes: How to Spot & Stop Structural Damage

Carpenter ants are not just a nuisance they’re one of the most destructive pests Seattle homeowners face. Unlike sugar ants that trail across your counters, carpenter ants tunnel inside wood framing, beams, and siding, weakening your structure over time.

What Do Carpenter Ants Look Like?

  • Large, black or red-and-black ants (¼–½ inch long).
  • Often seen at night, foraging for food in kitchens or bathrooms.
  • Sometimes mistaken for termites, especially when they have wings.

Key Difference: Carpenter ants don’t eat wood they carve smooth galleries inside it to build nests.

Signs of a Carpenter Ant Infestation

Seattle property owners should watch for:

  • Sawdust-like shavings (frass) near baseboards, windows, or crawlspaces.
  • Rustling sounds inside walls at night.
  • Winged swarmers emerging in spring or summer.
  • Ant trails leading to damp or rotting wood.

Why Seattle Homes Are at Risk

Moisture is the #1 attractant. Carpenter ants often nest in:

  • Water-damaged beams or window frames.
  • Crawlspaces with high humidity.
  • Decks, porches, or siding exposed to rain.
  • Attics with roof leaks.

Why DIY Carpenter Ant Control Fails

Store-bought sprays kill a few visible ants but leave the colony intact. Carpenter ants often split nests into satellite colonies, so treating one spot won’t solve the problem.

Professional exterminators use:

  • Moisture inspection tools to locate hidden nests.
  • Non-repellent treatments that reach the colony.
  • Wood-safe injections to eliminate ants inside beams.
