By proofPest

Do you hear strange rustling sounds in the walls? Do you find small piles of sawdust-like debris around your home? If so, you might have some uninvited guests in your walls, known as carpenter ants! While it’s uncommon to find a carpenter ant nest in your wall, they can carve out a home in most soft or wet lumber, meaning exposed foundation during building could be threatened.

But fret not; our team at proof. Pest Control has your back. Keep reading to learn more about the signs of a carpenter ant nest in your wall and how we can help!

Why Do Carpenter Ants Infest Wood?

Carpenter ants, despite their name, don’t wield hammers or saws. They’re, in fact, quite the opposite: natural builders. These diligent insects don’t eat wood, but they sure love to make it their home. This is where the trouble begins.


These pests establish their nests in various types of wood, and your home’s walls can be an attractive option. Unlike termites, carpenter ants don’t consume wood for sustenance but excavate it to create a network of tunnels and chambers. These nests can remain hidden for a long time, causing structural damage to your house in the process.

Signs of a Carpenter Ant Nest in Your Wall

Detecting a carpenter ant nest in your wall early is essential to prevent significant damage. Here are some telltale signs to watch out for:



  • Rustling Noises: If you hear faint rustling sounds coming from your walls, it could be carpenter ants at work. They are remarkably quiet, making them experts in the art of stealth.
  • Sawdust: Carpenter ants don’t consume wood but still push the debris from their excavations out of tiny holes. You may see growing piles of sawdust near the site of an infestation, with frass and insect body parts intermingled within. 
  • Visible Ants: Sometimes, you might spot carpenter ants, particularly during their foraging activities. Keep an eye out for large black or reddish-brown ants with segmented bodies.
  • Damaged Wood: Inspect your walls for any wood that appears hollowed out or weakened. Remember that this could also indicate the work of another wood-destroying insect: termites. A thorough inspection by a pest professional can determine the type of infestation. Check out this guide for more information about checking for damaged or rotting wood.

Why Carpenter Ants Choose Your Walls

Carpenter ants aren’t just randomly picking your walls for their nests. Key features draw them to your walls or other wood inside your home. Here’s why you may find a carpenter nest in your wall and what causes them to overstay their welcome:

  • Moisture: Carpenter ants prefer damp and decaying wood, as it’s easier to excavate. Leaky pipes, condensation, or poor ventilation can create ideal conditions for these pests to thrive in your home’s wooden components.
  • Wood Condition: Older homes with wooden structures are more susceptible to carpenter ant infestations, partially because of the wear and tear of age. However, any type of wood can become vulnerable to carpenter ant damage, especially if they’ve excavated existing damaged structures. 
  • Protection: Your walls offer protection from predators and harsh weather conditions. Carpenter ants are experts at finding cozy, sheltered spots for their nests.
