Signs You Have Carpenter Ants

By Acme Homes 6-20-2023

You love your home. It provides you safety and comfort. Unfortunately, there are pests who might like your home for those same reasons. One pest in particular you need to be on the lookout for is carpenter ants. Carpenter ants are destructive pests that can cause damage to wooden structures in your home. Here are some signs that your home may have carpenter ants and what you can do about them.

Presence of Ants

Carpenter ants are usually larger than other ant species, measuring around ¼ to ½ inch (6-13 mm) in length. If you notice large black or reddish-brown ants in your home, particularly near wooden structures or along ant trails, it may indicate a carpenter ant infestation.

Sawdust or Frass

Carpenter ants excavate tunnels and galleries in wood to build their nests. As they do so, they push out wood debris called "frass" or sawdust. If you find piles of sawdust-like material near wooden structures, such as windowsills, baseboards, or in your attic, it could be a sign of carpenter ants.

Audible Noises

If you listen carefully near infested wood, you may hear faint rustling or munching sounds as carpenter ants tunnel through the wood.

Hollow or Damaged Wood

Carpenter ants hollow out galleries within wood, weakening its structure. Tap on wooden surfaces to check for hollow sounds or inspect the damaged wood for smooth tunnels, galleries, or windows that carpenter ants create.


In spring or summer, carpenter ant colonies produce winged reproductive ants, known as swarmers, that leave the nest to mate and establish new colonies. If you notice winged ants indoors or find discarded wings near windows, it could indicate a nearby carpenter ant nest.

Nesting Sites

Carpenter ants prefer damp and decaying wood but can also infest dry wood. Common areas where you may find their nests include attics, crawl spaces, wall voids, wooden porches, decks, or structures in contact with soil.

If you suspect a carpenter ant infestation in your home, it's essential to take prompt action to minimize the damage. Here's what you can do.

Identify and Eliminate the Nest

Locate the carpenter ant nest(s) by following ant trails and signs of activity. Once located, you can treat the nest directly using appropriate ant control products, such as baits, dusts, or liquid insecticides. If the infestation is extensive or inaccessible, consider contacting a professional pest control service.

Remove Food and Water Sources

Carpenter ants are attracted to food and water. Keep your home clean, store food in sealed containers, and fix any plumbing leaks or sources of moisture to deter ant activity.

Trim Vegetation

Trim trees, shrubs, or any vegetation that comes into contact with your home. This helps eliminate bridges for ants to access your house.

Seal Entry Points

Seal cracks, gaps, and other entry points around your home, including windows, doors, and foundation, to prevent ants from entering.

Remove Attractive Wood Sources

Remove or replace any damaged or decaying wood in and around your home, as it is attractive to carpenter ants. Ensure that firewood and other woodpiles are stored away from your house.

It's important to note that severe or persistent carpenter ant infestations may require professional assistance. Pest control experts have the knowledge and tools to effectively identify and treat carpenter ant colonies, ensuring thorough eradication and preventing future infestations.
