Carpenter Ant

Carpenter Ant

Carpenter ants (Camponotus) are fascinating insects known for their ability to excavate wood to create nests and galleries. Unlike termites, which consume wood as food, carpenter ants do not eat wood but instead tunnel through it to build their colonies. They are an important part of the ecosystem, playing a role in breaking down decaying wood and aiding in nutrient cycling. However, when they infest homes and other structures, they can cause significant damage over time.

Carpenter Ants vs Termites

  • Appearance: Carpenter ants are larger than termites, ranging from about 6 to 12 mm in length. They have a segmented body with a narrow waist and elbowed antennae. They can vary in color from black to reddish-brown.  Termites are generally smaller than carpenter ants, ranging from 4 to 15 mm long. They have a soft body and straight antennae and are usually light in color, ranging from white to light brown.
  • Diet: Carpenter ants feed on sugars and proteins, including insects, honeydew, and plant secretions. They forage for food both indoors and outdoors, making them versatile pests.  Termites primarily feed on wood but can consume paper, books, and other cellulose-based materials. They forage for food 24/7, making them relentless pests that can cause extensive damage quickly.
  • Damage:  While carpenter ants do not consume wood as food, their nesting activities can cause significant structural damage over time. Infestations can weaken wooden beams, siding, and other structural components, leading to costly repairs. 
  • Behavior: Unlike termites, carpenter ants do not eat wood. Instead, they excavate wood to create nests and galleries, which can weaken the structure of buildings and other wooden objects. They prefer moist or decaying wood but can also infest dry, sound wood.

Signs of Carpenter Ants

  • Trails: Physically seeing them, especially during the spring and summer months.
  • Wood Shavings: Presence of sawdust-like material called frass near nesting sites.
  • Swarms: During swarming season, they will leave the nest to swarm and mate and create new colonies.
  • Aphids: These ants tend to aphids for their honeydew secretions. If you notice aphids, then carpenter ants may be nearby.
  • Damage: Hollow trees and branches are a nesting site, especially if the wood is damp or decaying.
  • Moisture: They are attracted to moisture. Areas such as standing water, leaky pipes, or damp soil can provide ideal conditions for colonies.


How to Get Rid of Carpenter Ants

A multi-step approach that targets both the ants themselves and their nesting sites is ideal;

  • Identify and Locate Nests: Locate nests typically found in damp or decaying wood. Look for signs of ant activity, such as sawdust-like material (frass), wood shavings, or ants themselves.
  • Eliminate Food Sources: They are attracted to sweet and protein-based foods. d promptly clean up spills.
  • Seal Entry Points: Seal cracks, gaps, and openings in walls, doors, windows, and foundation. Use caulk or sealant to close off potential entry points.
  • Trim Vegetation: Trim trees, shrubs, and other vegetation away from the exterior of your home.
  • Remove Moisture Sources: They are attracted to moisture. Fix leaks, repair plumbing, and improve ventilation to reduce humidity levels and eliminate water sources that attract ants.
  • Professional Pest Control: If the infestation persists or if you're dealing with a large colony or hard-to-reach nests, consider hiring a professional pest control service.

It's crucial to address carpenter ant infestations promptly to minimize damage and prevent structural issues. Professional pest control services can help identify and treat infestations effectively and provide recommendations for preventing future problems. Regular inspections and maintenance can also help detect and address carpenter ant activity before significant damage occurs.


Getting rid of carpenter ants, especially in severe infestations, will require time and persistence. Regular monitoring and preventive measures can help prevent future infestations. Overall, identifying and addressing infestations promptly is essential to prevent significant damage to wooden structures.


If you suspect a carpenter ant infestation in your home or yard, it's recommended to contact a pest control professional like Four Seasons Pest Control for proper inspection and treatment.

  • What do Carpenter Ants Look Like?

    Carpenter ants vary in size but are typically larger than other ant species. Sizes are between 1/4 to 3/4 inches in length.


    They have a segmented body with three distinct body parts: head, thorax, and abdomen.


    Colors range from black to red, and some species may exhibit a combination of colors.


    Will have wings during certain stages of their life cycle.

  • What is the Difference Between Carpenter Ants vs Termites?

    Ants have a narrow waist and bent antennae. Termites have a broad waist and straight antennae.


    Termites are lighter in color and have a uniform body. Ants have a dark-colored body with segmented body parts.

  • Do Carpenter Ants Have Wings?

    Yes, they do have wings, but not all of them. The colony consists of castes, including winged reproductive ants (swarmers), workers, and the queen.


    Winged reproductive ants are responsible for mating and establishing new colonies. These ants have wings and are often seen during the swarming season, typically in the spring or summer months. After mating, the winged ants shed their wings and establish new colonies.


    On the other hand, workers are wingless and make up most of the ant colony. They are responsible for foraging for food, caring for the young, and maintaining the nest.


    The presence of winged carpenter ants indoors, particularly in large numbers, may indicate an established colony nearby or within the structure.

  • Do Carpenter Ants Bite?

    Yes, they are capable of biting. However, they typically do so only when they feel threatened or are defending their nest. The jaws are designed for cutting and gripping rather than for delivering venomous stings like some other insects, such as bees or wasps.


    While carpenter ant bites are not usually as painful or harmful as those of some other ant species, they can still cause irritation, especially if the ant injects formic acid into the wound. Formic acid is a substance found in the bodies of ants that can cause a burning sensation and mild irritation.


    In most cases, carpenter ant bites result in minor discomfort, redness, and swelling at the bite site. However, some individuals may experience more severe reactions, mainly if they are allergic to ant venom or if the bite becomes infected.


    To avoid being bitten by carpenter ants, it's essential to avoid disturbing their nests and to take preventive measures to keep ants out of living spaces.

  • What are the Characteristics of Carpenter Ants?

    Carpenter ants do not eat wood but excavate it to build nests.


    They typically forage for food outside, feeding on insects, honeydew, and other sweet substances.


    Carpenter ants have different castes within the colony, including workers, soldiers, and the queen.


    Queens are typically larger than workers and have wings until they establish a new colony.
