Ant-agonists: The Best Exterminators for Carpenter Ants

by | Aug 1, 2025

 

Why Finding the Best Exterminator for Carpenter Ants is Critical

The best exterminator for carpenter ants can save your home from thousands of dollars in structural damage. These wood-destroying insects don’t eat wood like termites; they excavate it to create nests, weakening your home’s framework over time. A professional should be licensed, insured, and have specific experience with carpenter ants, backed by positive reviews and a service guarantee.

Carpenter ants are among the largest ants in North America, ranging from 1/4 to 5/8 inch long, with narrow waists and bent antennae. A mature colony can contain tens of thousands of workers, and the damage they cause by tunneling through wood can compromise your home’s structural integrity.

Professional extermination typically costs between $300 and $1,500+ depending on the infestation’s severity and your home’s size. Please note: These are average costs based on internet data and do not reflect the specific pricing of Biggins Exterminating services.

The key challenge is that carpenter ants often establish multiple satellite colonies. Missing even one nest can lead to re-infestation, which is why professional expertise is crucial for complete elimination.

As Stephen Biggins, owner of Biggins Exterminating Co., I’ve helped Massachusetts homeowners eliminate carpenter ant infestations for over four decades. Our family-owned business is one of the most trusted names when searching for the best exterminator for carpenter ants, and our warranty-backed approach ensures these pests don’t return.

Identifying the Enemy: Carpenter Ant Infestations and Damage

Before you can get rid of carpenter ants, you need to understand who they are and what clues they leave behind. Identifying an infestation early is your first line of defense in protecting your home.

Carpenter Ants vs. Termites: Know the Difference

It’s a common mix-up, but knowing the key differences between carpenter ants and termites is crucial for getting the right treatment.

  • Carpenter Ants: These are large ants (1/4 to 5/8 inch) that are typically black or reddish-black. They have a narrow, pinched waist, bent (“elbowed”) antennae, and their front wings are longer than their back wings. They excavate wood to build nests, leaving behind smooth, clean galleries.
  • Termites: Termites have a broad, thick waist, straight antennae, and four wings of equal length. They eat wood, leaving behind rough, mud-lined tunnels.

Understanding these distinctions is vital for proper identification. For a more detailed look, read our guide on How to Distinguish Carpenter Ants from Termites.

Telltale Signs of a Carpenter Ant Problem

Carpenter ants leave behind several clues that can tip you off to an infestation. Keep an eye out for these signs:

  • Foraging Worker Ants: Seeing large, black ants, especially at night, marching across your kitchen or bathroom is a common first sign.
  • Frass: Piles of what looks like sawdust are a clear indicator. This is a mix of wood shavings, insulation, and insect parts that ants push out of their tunnels. You’ll often find it near baseboards or window sills.
  • Faint Rustling Sounds: In quiet moments, you might hear faint rustling or crinkling sounds from within your walls as the ants work.
  • Swarmers or Discarded Wings: Finding winged ants or their delicate, discarded wings on sills or near lights is a strong sign of a mature colony. This is common in late winter or early spring in Massachusetts. Learn more in our article, Do Carpenter Ants Have Wings?.
  • Damaged Wood: Look for small, slit-like openings on wood surfaces. The tunnels inside are smooth and clean, almost as if they’ve been sandpapered.

The Damage They Cause

The real concern with carpenter ants is the hidden damage they inflict. They don’t eat wood, but they excavate it to create nests and tunnel systems (galleries). They often start in wood softened by moisture, like around leaky pipes or roofs, but can expand into sound, dry wood, compromising your home’s structural integrity.

Over time, this tunneling can weaken crucial wooden components like beams, floor joists, and wall studs. While they work slower than termites, a long-term, unchecked infestation can lead to significant and costly damage. Signs of severe damage can include hollow-sounding wood, buckling floors, or visible warping of wooden structures. Protecting your home from this threat is why finding the best exterminator for carpenter ants is so crucial. For more insights, explore our page on Pest Control for Carpenter Ants.

The Professional Solution: Why and How Exterminators Eliminate Carpenter Ants

Once you’ve identified the enemy, the next step is elimination. While DIY solutions are tempting, carpenter ants present unique challenges that often require a professional touch, especially since they establish multiple “satellite colonies” that are hard to find. Missing even one nest means the problem will return. For homeowners in Massachusetts, understanding The Importance of Hiring a Professional Pest Control Service in Massachusetts is key.

When to Call a Professional vs. DIY

For a few random ants, cleaning and sealing might work. But for carpenter ants, DIY methods often fall short and can even make the problem worse by causing the colony to scatter. We strongly recommend calling a pro if you see:

  • Persistent Ant Sightings: Seeing ants regularly, especially at night, signals an established colony.
  • Visible Wood Damage: Any frass, hollow-sounding wood, or tunnels are red flags that DIY methods can’t fix.
  • Hidden Nests: Professionals have the tools and experience to locate all nests, including the main colony and any satellite nests hidden in walls or ceilings.
  • Large-Scale Infestations: Seeing winged “swarmers” means you have a mature colony that requires expert handling.

Professional Extermination Methods Explained

A professional exterminator provides a science-backed plan to eliminate the entire colony. The process typically includes:

  • Thorough Inspection: The foundation of any successful treatment is a detailed inspection of your property, inside and out, to find signs of activity, moisture issues, and entry points.
  • Nest Location: Using specialized tools and techniques, experts locate the main parent colony and all satellite nests, which may be hidden in walls, attics, or outdoors.
  • Targeted Treatment Options: A combination of methods is custom to your situation. This often includes dusts (like boric acid) applied into wall voids and crevices, which ants carry back to the colony. Specialized baits are also used, which foraging ants take back to share, eliminating the colony from within, including the queen.
  • Liquid Insecticides: These are often used for perimeter treatments around your home’s foundation to create a protective barrier. For nests deep inside walls, we may perform a wall void application, injecting treatments directly into the colony’s heart.
  • Follow-Up Visits: Especially for large infestations, follow-up visits are crucial to monitor progress and ensure the colony is completely eradicated. This dedication is what sets the best exterminator for carpenter ants apart.

Eliminating Ant Attractants

Carpenter ants are always looking for moisture, food, and shelter. Removing these attractants makes your home far less appealing.

  • Control Moisture: This is the most important step. Carpenter ants love damp wood. Promptly fix leaky pipes, faucets, and roofs. Ensure gutters direct water away from the foundation and improve ventilation in basements, crawl spaces, and attics. Replace any water-damaged or rotting wood.
  • Remove Food Sources: Store all food, including pet food, in airtight containers. Clean up crumbs and spills immediately, especially in the kitchen. Use garbage cans with tight-fitting lids and empty them frequently. Keep compost bins located well away from your house.

Blocking Entry Points

Even a clean, dry home can be vulnerable if ants can find a way in. Seal up any potential entry points to create a physical barrier.

  • Seal Cracks and Gaps: Inspect your foundation, windows, and doors, and use caulk to seal any cracks or openings. Pay close attention to where utility pipes and wires enter the home.
  • Repair Screens: Ensure all window and door screens are in good repair, with no rips or tears.
  • Trim Vegetation: Keep tree branches and shrubs trimmed back a few feet from your home’s exterior to eliminate “ant bridges” to your siding and roof.
  • Store Firewood Properly: Keep firewood stacks at least 20 feet from your home and liftd off the ground. Always inspect wood for ants before bringing it inside.

By partnering with a professional for the initial extermination and then applying these prevention strategies, you create a powerful defense to keep your home ant-free.

Frequently Asked Questions about Carpenter Ant Control

It’s natural to have questions when facing a carpenter ant problem. Here are clear answers to some of the most common concerns we hear from homeowners.

What do carpenter ants eat?

This is a common misunderstanding: carpenter ants do not eat wood. They excavate it to build their nests and tunnels. Their actual diet consists of proteins and sugars. Outside, they eat other insects and the sweet honeydew left by aphids. Inside your home, they forage for sweets, crumbs, pet food, and other insects. They are constantly searching for food and water to bring back to the colony.

How long does it take to get rid of carpenter ants?

The timeline depends on the size of the infestation, the number of satellite nests, and the treatment methods used. While you may see a reduction in ant activity within a few days of professional treatment, it can take a few weeks for the entire colony to be eradicated. This is because the treatment needs to reach the hidden nests and eliminate the queen. Follow-up visits are often necessary to ensure complete elimination and provide lasting relief.

Are carpenter ant bites dangerous?

Carpenter ant bites are generally not considered dangerous, as they are not venomous. However, they can be painful. If a carpenter ant feels threatened, it will bite with its strong jaws and may spray formic acid into the wound, causing a temporary burning sensation. While a nuisance, the bite is not a major health threat to people or pets.
