Previously we learned why we get carpenter ants and what you should do if you find carpenter ants at home. Now Let’s explore what steps you can take to eliminate a colony. Remember, carpenter ants are tricky to control, so if you’re unsure what to do give us a call and one our ant control technicians will help you out.
TLDR;
- Carpenter ant colonies live in moist or damaged wood and often include multiple nesting sites
- Signs include frass, rustling noises in walls, and repeated sightings of large ants indoors
- Finding the main nest is critical since killing visible ants won’t eliminate the colony
- Direct treatments like dusts, foams, or targeted insecticides work best inside the nest
- Baits can help when nests are hidden, allowing ants to carry treatment back to the colony
- Fixing moisture issues and removing damaged wood helps prevent reinfestation
- Ongoing activity usually means satellite nests are present and need to be addressed

How To Eliminate A Colony
In order to eradicate a colony, the primary nest must be detected and destroyed. You can attempt to do this yourself, or hire an expert in Metro Vancouver who knows exactly what to look for, and how to track the nest. It’s not always easy to track the ants back to their nest because they’re usually most active at night, so patience will be your biggest asset once you know what to look for.
Oh, and be careful once you’ve found the nest as carpenter ants can, and will, bite humans if necessary. Biting is a defensive measure, and will only occur if the ants feel their nest and offspring are threatened. The bite can be painful, especially when combined with the formic acid they can spray into the wound to cause a burning sensation. It won’t kill you, but it can really hurt, especially if you end up with more than one bite. If you do happen to be bitten by carpenter ants, wash the wounds with soap and water, then apply a topical antibiotic cream.
Eliminating ants in Vancouver and elsewhere requires pretty much the same strategy. You have to go after the queen, the eggs and the larvae or chances are good you’ll simply exacerbate the problem.
Carpenter Ant Nest Treatment in a Retaining Wall
One place to start is to eliminate food sources for carpenter ants, in particular aphids. However, the carpenter ant’s “sweet tooth” will take it long distances to find aphids, giant whitefly and scales, so it’s not a highly effective means of control.
There are many products available on the market for eliminating ant colonies; naturally some are more effective than others, and how you tackle the problem will depend on whether you know where the nest is or not.

Spraying with insecticides or repellents isn’t the most useful way to go as sprayed-on insecticides will only kill the carpenter ants that are exposed to the killing agent, and while you may kill a bunch of them, you actually risk having the queen go into egg-laying overdrive to repopulate the colony, which could well make the original problem bigger than it was. As well, ants can sense most of the chemical repellants, so they simply learn to avoid the deadly toxins. If the spray comes too near the nest, the workers will simply move the eggs to a new location.
In order to eliminate a nest, therefore, it is best to apply non-repellent borates into the wall cavities that will kill the carpenter ants within seven to 14 days after contact. The non-repellant borates work because the ants can’t detect them, and so carry the chemicals back into the nest to spread their toxicity around. If the wall cavities surrounding the nest have all been injected, then a more toxic treatment can be applied, targeting the nest location(s) only.
Industry experts agree that most over-the-counter options available at your local hardware store are not strong enough to be effective, as their potency is not nearly as harsh as professional-grade products.
Many of the most effective products require a trained technician who is a licensed applicator. Proper care and handling is essential. If you do plan to use retail products, read the instructions carefully and follow all directions exactly. Also, be sure to check whether the product is specifically meant for carpenter ants, as not all ant-killing products are up to the challenge.
To properly and effectively tackle an infestation of carpenter ants, a professional pest control program in Vancouver is essential. Using the right expertise, techniques and products, Westside Pest Control has been successfully eliminating carpenter ants for over 10 years.

How To Get Rid Of Carpenter Ants In Walls
When carpenter ants are in your walls, surface treatments won’t cut it. You need to get inside their space.
Here’s how to approach it:
- Listen and locate activity
Nighttime rustling helps narrow down where they’re nesting - Drill small access holes
Target the area where frass or sound is strongest - Apply dust or foam insecticide
These spread through the galleries where ants live - Monitor for continued activity
A drop in sightings usually means you’ve hit the right spot
If you miss the main nest, ants may shift to another area nearby. That’s why tracking matters before treating.
Westside Pro Tip
If you’re thinking about killing a carpenter ant nest yourself, slow down for a second.
The biggest mistake we see is treating too early, before finding the core nest.
Take a day or two to watch their movement. Where are they coming from at night? Where do they disappear?
Once you know that, your treatment becomes targeted instead of guesswork. Less wall damage, better results.
FAQs
What is the best way to kill carpenter ants?
The most effective method is direct nest treatment. That usually means applying dust or foam insecticide into the galleries where ants are living. Baits can help when the nest is hidden, but they take longer. Killing the visible ants alone won’t solve the problem if the colony is still active behind the scenes.
Can I control carpenter ants on my own?
You can handle smaller or localized issues if you’re able to find the nest. Basic tools like dusts, foams, and baits can work when used correctly. The challenge is locating all nesting areas. Larger infestations often involve multiple nests, which makes full control harder without a more thorough approach.
Why do carpenter ants keep coming back after treatment?
If they return, something is still attracting them. Moisture is a big one, especially in damaged or damp wood. There may also be satellite nests nearby that weren’t treated. Carpenter ants spread their colonies out, so removing one area doesn’t always eliminate the entire population unless all nesting sites are addressed.
