If you’ve spotted carpenter ants inside your house, it’s important to act quickly.

What Are Carpenter Ants?

Carpenter ants (Camponotus spp.) are large, black or reddish ants that are commonly found in North America. Unlike termites, carpenter ants don’t eat wood, but instead, they tunnel through it to create their nests. They can be found in both outdoor and indoor environments, with nests often located in moist or decaying wood, making your home’s structure vulnerable to damage over time.

Why Are Carpenter Ants a Threat?

While carpenter ants don’t eat wood like termites, their ability to carve out extensive tunnels can weaken structural wood in your home, which may lead to costly repairs if not dealt with promptly. If left unchecked, carpenter ants can destroy beams, door frames, windowsills, and other wood structures within your walls, floors, or attic. Moreover, carpenter ants are social insects, meaning their colonies can grow quickly, leading to a large infestation.

How to Identify Carpenter Ants in Your Home

Before you can effectively eradicate carpenter ants, you need to be able to recognize their presence. Here are a few common signs to look out for:

Large, black or red ants: Carpenter ants are typically larger than other ant species, ranging from 1/4 to 1/2 inch in length.
Frass (sawdust-like material): As carpenter ants tunnel through wood, they push out debris, which can look like wood shavings or sawdust.
Hollow or damaged wood: Carpenter ants prefer moist, decaying wood. If you notice any hollowed-out wood in your home, it could be a sign of an infestation.
Noise: Sometimes, carpenter ants make a soft rustling sound inside the walls as they tunnel, though this is more commonly heard in the evening.

Common Areas Where Carpenter Ants Nest

Carpenter ants are likely to nest in areas with access to moisture. Here are the most common places to check:

Attics and crawlspaces
Basements
Windowsills and door frames
Behind insulation or siding
Around plumbing and pipes, especially in the kitchen or bathroom

The Step-by-Step Process to Get Rid of Carpenter Ants

Now that you know how to identify carpenter ants, let’s dive into the process of eradicating them from your home. It’s essential to act quickly, but with patience and persistence, you can get rid of them once and for all.

Step 1: Locate the Nest

The first step in eliminating carpenter ants is finding their nest. This can be tricky since ants may create multiple colonies or build their nests in hard-to-reach areas. Follow these steps:

Look for trails of ants leading to and from areas of moisture.
Inspect dark or damp areas of your home, such as the attic, basement, and behind wooden fixtures.
If you find frass or sawdust near a wall or wooden surface, it could indicate the presence of a nest inside the wood.

In some cases, carpenter ants may have multiple satellite nests. Keep this in mind as you move on to the next steps.

Step 2: Eliminate Food and Water Sources

Carpenter ants, like all pests, are drawn to food and water. Remove any sources of food or water that may attract them. This includes:

Cleaning up any crumbs or spills.
Fixing leaky pipes or faucets.
Cleaning out trash cans and sealing them tightly.

By eliminating these attractants, you’ll make your home less appealing to the ants and force them to seek shelter elsewhere.

Step 3: Apply Ant Baits

Ant baits are one of the most effective methods for eradicating carpenter ants. These baits contain poison that ants will carry back to their nest, poisoning the colony. Here’s how to use them:

Place ant bait stations along the trails where you’ve seen carpenter ants.
Choose a bait that is designed specifically for carpenter ants.
Be patient, as it may take several days or even weeks for the bait to eliminate the entire colony.

Step 4: Use Insecticidal Sprays

If baits aren’t enough to eliminate the infestation, you can also use insecticidal sprays. These should be applied directly to areas where carpenter ants are active. Make sure to use a product labeled for carpenter ants and follow all safety instructions. Target areas such as:

Window frames
Baseboards
Wooden beams or structures

Spraying along ant trails can help eliminate ants in their tracks, but be sure to apply the treatment to entry points and nesting areas for more effective results.

Step 5: Seal Entry Points

Carpenter ants may enter your home through cracks or gaps in your walls or foundation. Sealing these entry points is critical in preventing future infestations. Here’s how you can do it:

Inspect your home’s exterior for any cracks, gaps, or holes.
Use caulk or weatherstripping to seal these openings.
Inspect and repair damaged window screens.

By sealing these entry points, you’ll prevent ants from entering and re-establishing a nest in your home.

Step 6: Prevent Future Infestations

After you’ve eliminated the carpenter ants, it’s essential to take preventive measures to keep them from coming back. Regular maintenance of your home can go a long way in keeping carpenter ants at bay:

Regularly inspect your home for signs of moisture damage or decay.
Maintain proper drainage around your home to prevent water buildup.
Trim back trees and shrubs that are close to your home, as ants may use them as bridges into your house.

Troubleshooting Tips for Carpenter Ant Infestations

Even after following the steps above, you may encounter challenges in eliminating carpenter ants. Here are some common troubleshooting tips:

Multiple Nests: Carpenter ants can have more than one nest. If you’re not seeing progress, consider checking for satellite nests or expanding your treatment to new areas.
Reinfestation: If you continue to see ants after applying bait or insecticide, ensure all entry points are sealed and reapply treatments if necessary.
Professional Help: If your infestation is severe or persistent, you may need to contact a pest control professional who specializes in carpenter ants.
