How To Identify an Carpenter Ant

Carpenter ants have one node (bump between the middle and read body sections). They are typically black or black with a reddish-brown body. They have an evenly rounded thorax which differentiates them from Field ants.

These ants do vary in size.

Where Do They Come From

Carpenter ants establish nests in wood, especially decaying wood. They have a primary nest and separate satellite nests (may occur indoors).

How To Keep Ants Away

  • Trim back any shrubs or trees that come into contact with buildings. When plants touch a home or building they create an easy way for ants to crawl onto and access the building.
  • Seal all potential ant entryways. Common entry ways are around windows, doors, and utility lines.
  • Keep dry pet food in sealed bins and clean up any spills.
  • Remove and replace water-damaged or decaying wood.

How To Get Rid Of Carpenter Ants

  • Try to locate and destroy all nests by following ant trails from food source to the nest. Carpenter ants typically forage at dusk. Carpenter ants typically have multiple nests.
  • Use an insecticidal bait, especially during winter through early spring with populations are small. Try several baits to see what the ants prefer. Carpenter ants can be difficult to control with baiting alone.
  • Apply a slower acting and non-repellent insecticide on the exterior foundation, around windows and doors and other possible ant entry points.
  • Controlling carpenter ants is difficult, so consider hiring a pest management professional to help.
