Carpenter ants

Big black ants inside? Don’t wait for spring

Carpenter ants dig nests in damp or damaged wood — window frames, decks, roof edges. Seeing them indoors, even in fall or winter, often means a nest inside the house.

Book a spring prevention treatment now and you’re first on the schedule when the season starts.

Call us if you see:

  • Large black ants inside, especially at night
  • Fine sawdust near baseboards or windows
  • Winged ants coming out of a wall
  • Ant trails to food, pet bowls or sinks

FAQ

Questions we get every day

Why are there ants in my house in the fall?

Ants active indoors in cold months usually have a nest inside the walls or floors. That needs a targeted treatment — store baits rarely reach it.

Are carpenter ants dangerous for my house?

They don’t eat wood, but they hollow it out to nest. Over time that can damage window frames, decks and structure, so it’s best to act early.
