Carpenter ants are notorious for causing structural damage to homes and buildings. Unlike termites, they don’t eat wood, but they do hollow it out to create nests. If you’ve noticed large, black ants in your home, particularly near wooden structures or moist areas, it’s likely that you have a carpenter ant infestation. While these ants are an essential part of the ecosystem outdoors, having them in your home can lead to expensive repairs if left unchecked.
In this guide, we’ll explore practical, effective methods to get rid of carpenter ants, prevent future infestations, and ensure your home remains safe and ant-free.
What Are Carpenter Ants?
Carpenter ants are large ants, typically black or dark brown, and they range in size from 1/4 inch to 1/2 inch. These ants build their nests by tunneling through wood to create their colonies. Unlike termites, carpenter ants don’t consume the wood they remove, but their activity weakens the structural integrity of the wood over time.
If you notice piles of fine wood shavings near beams, walls, or other wooden structures, it’s a sign that carpenter ants might be active. These ants are especially attracted to damp or decaying wood, so areas with water damage or leaks are at higher risk.

How to Get Rid of Carpenter Ants
Here are some effective steps to eliminate carpenter ants and prevent them from coming back.
1. Identify the Source of the Infestation
Before taking action, it’s essential to locate the source of the infestation. Carpenter ants typically nest in moist, decaying wood. Start by inspecting areas like:
- Wooden beams, door frames, and window sills
- Attic spaces, basements, and crawlspaces
- Areas around plumbing leaks or water damage
- Wooden furniture
Once you find their nest, you can focus on treating the right areas.
2. Clean and Remove Attractants
To make your home less inviting to carpenter ants, clean up food and water sources. Carpenter ants are attracted to sugary foods and moist environments. Remove any spilled food or crumbs, and ensure that there are no leaking pipes or damp areas inside the home. Consider using caulking to seal up cracks or holes in your home’s foundation where ants could enter.
3. Use Ant Baits
Ant baits are one of the most effective tools for eliminating carpenter ants. These baits contain poison that worker ants take back to the nest, which ultimately kills the entire colony. Place the baits near trails, entry points, or where you’ve spotted the ants. It can take a few days or weeks for the bait to work, so patience is key.
4. Diatomaceous Earth
Diatomaceous earth is a natural, non-toxic substance that can be used to control ants. It’s made from the fossilized remains of aquatic organisms, and when ants come in contact with it, it dries out their exoskeletons, leading to death. Sprinkle diatomaceous earth around areas where ants are active, such as entry points or near nests. It’s an eco-friendly option that’s safe for pets and children when used properly.
5. Insecticidal Sprays
Insecticidal sprays can provide immediate results, but they should be used with caution, especially if you have pets or children in your home. Choose a spray labeled for carpenter ants and follow the instructions carefully. Apply the spray to cracks, crevices, and around wooden structures where the ants are active. Be mindful that sprays may only kill the ants you see, but not the entire colony.
6. Call a Professional Exterminator
If the infestation is large or persistent, it may be best to contact a professional pest control service. Experts can identify the source of the infestation, assess the extent of the damage, and implement more advanced solutions, such as fumigation or targeted insecticide treatments.
How to Prevent Carpenter Ants in the Future
After eliminating the current infestation, it’s essential to take preventive measures to keep your home ant-free. Here are some helpful tips:
1. Fix Leaks and Water Damage
Carpenter ants are attracted to damp wood, so ensure there are no leaks in your plumbing or roof. Regularly inspect areas like your attic, basement, and around windows for signs of moisture damage.
2. Trim Trees and Shrubs
Carpenter ants can easily gain access to your home through branches that touch your house. Trim any overhanging trees or shrubs that could create a pathway for ants to enter your home.
3. Seal Entry Points
Inspect your home for cracks and gaps, particularly around windows, doors, and the foundation. Use caulk or weatherstripping to seal any potential entry points that ants could use.
4. Maintain Cleanliness
Keep food storage areas clean and seal up food in airtight containers. Regularly vacuum floors and wipe down counters to eliminate crumbs and attractants that could lure ants back into your home.
5. Treat Wooden Structures
If you live in an area where carpenter ants are common, consider treating your wooden structures with a borate-based preservative. This will help protect your home’s wood from future infestations.
FAQs About Carpenter Ants

While carpenter ants don’t bite or sting in most cases, they can cause significant damage to your home’s structure by hollowing out wood to create nests. Over time, this can weaken beams, support structures, and walls.
2. How do I know if I have carpenter ants?
Look for large black or reddish-brown ants. You may also notice wood shavings or frass near walls, beams, or around wooden furniture. Carpenter ants are usually more active at night, so they may be easier to spot after dark.
3. Can carpenter ants infest my kitchen?
Yes, carpenter ants are attracted to sugary foods, so they can invade your kitchen if there are food sources available. Keeping your kitchen clean and sealed is crucial to preventing ants from entering.
4. Do carpenter ants live indoors?
Carpenter ants can live both indoors and outdoors. They often enter homes in search of food and moisture. If you have a colony indoors, it could be nesting in wooden structures or areas with water damage.
5. How do I get rid of carpenter ants naturally?
Using natural remedies like diatomaceous earth or vinegar can help control carpenter ants. These substances are safe and effective for homeowners looking for eco-friendly options. However, severe infestations may require professional help.
Carpenter ants can be a significant nuisance, but with the right approach, you can successfully get rid of them and prevent future infestations. By staying vigilant, maintaining your home, and using the appropriate pest control methods, you can keep your home safe from these destructive pests.
