Carpenter ants are one of the most common household pests. While a single carpenter ant sighting may not seem alarming, it could indicate a larger hidden problem. They do not feed on wood, but they burrow through it to create nests, which can leave an impact on the structural integrity of your home over time.
In this guide, you’ll learn when to worry about carpenter ants, how to spot signs of an infestation, and how to get rid of them.
These methods can be crucial in the initial stages of an infestation. But for a full-blown carpenter ant infestation, seek help from professional pest control experts. Our team can provide a customized approach to protect your home effectively.
What are Carpenter Ants?
Carpenter ants are large black, red, or reddish-black ants that are known for their ability to excavate wood to create nests. They hollow out the wood rather than eating it, leaving behind smooth, polished galleries that can weaken wooden structures over time.Do Carpenter Ants Bite?
Carpenter ants are not generally aggressive, but they can bite if provoked. Their bites are not typically harmful, though they can cause irritation or a mild allergic reaction in some individuals. Carpenter ants also have the ability to sting, which can be painful and cause a localized reaction. However, their primary threat is the structural damage they can cause rather than their bites or stings.
Signs of Carpenter Ants in House
Spotting one carpenter ant does not always mean there is a full-blown infestation. However, it’s important to observe for the following signs of carpenter ant activity: Visible Carpenter Ants Large black or reddish ants roaming indoors, especially at night, as carpenter ants are nocturnal foragers. Frass (Wood Shavings) Piles of sawdust-like material near wooden structures, door frames, or baseboards. The wood debris expelled from the carpenter ants’ galleries is called frass. Rustling Sounds Soft rustling noises coming from inside walls, ceilings, or wooden beams may indicate ants burrowing into the wood. Discarded Wings Winged reproductive ants, also known as swarmers, may leave behind discarded wings near windows, doorways, or light fixtures. Carpenter ants are most active at night. If you spot large ants crawling around your home after dark, it’s a sign they may be foraging for food. Pay special attention to kitchen countertops, sinks, and pantries, as these areas often provide access to food and water.

Carpenter ants cause significant damage to homes by hollowing out wood to create their nesting galleries. They do not consume wood but excavate it, weakening beams, support structures, and flooring. Signs of carpenter ant damage include hollow-sounding wood when tapped, as the ants carve out smooth, clean tunnels within. These polished galleries differ from termite tunnels, which are rough and filled with debris. Damage can also lead to warped or sagging floors, especially if the ants nest beneath them. Frass, or wood shavings, is often found near entry holes, baseboards, window sills, and other wooden structures in case of an infestation.
How to Get Rid of Carpenter Ants
Getting rid of carpenter ants is essential to prevent serious structural damage to your home. These ants carve out wooden structures to create nests, and if left unchecked, they can weaken floors, walls, and beams. Fortunately, there are several effective DIY methods to control an infestation before it escalates. Locate the Nest To eliminate carpenter ants, you must first locate their nest. Look for signs like frass (wood shavings), hollow-sounding wood, and trails of ants. Follow the trails, as they often lead directly to the nest hidden inside wooden beams, walls, or furniture. Seal Entry Points Prevent carpenter ants from invading your home by blocking cracks, crevices, and gaps around windows, doors, and baseboards. Eliminate Food Sources Carpenter ants are drawn to food sources like crumbs and open food containers. Keep your home tidy and store food in sealed containers, and disposing of trash properly to remove potential attractants. Use Bait Traps Bait traps are an effective way to eliminate an entire colony. Place bait stations near areas where carpenter ants are frequently seen. The ants might carry the poisoned food back to the nest. There, it will kill the colony members, including the queen. Apply Insecticide Spray Insecticide sprays designed for carpenter ants can be applied directly to cracks, crevices, and suspected nest areas. Focus on entry points and active areas to target the ants at their source. Be sure to follow the product’s safety guidelines when applying insecticide indoors.How to Prevent Carpenter Ant Infestation?
