Carpenter ants can quickly become a serious problem if they infest your home. Unlike many harmless ant species, carpenter ants are larger, usually between half an inch and 5/8 of an inch, and can cause significant damage to wooden structures. Recognising them early is key to preventing costly repairs.

In this guide, we’ll share the best non-toxic methods to get rid of carpenter ants in Ajax in 2026. These methods are safe for households with children and pets and perfect for anyone looking for DIY solutions.

However, if you call a professional ants exterminator, then it’s their problem how they do it. So, here are all the non-toxic methods you can try to getting rid of the carpenter ants.

Use Baking Soda as a Bait

Baking soda is edible for human beings. But remember, consuming too much of it in a day can be toxic for even a healthy adult. The same goes for your pets. Baking soda is one of the pet-safe ants extermination methods. But, for the ants, it is POISON straight away.  Since all ants are attracted to sweets, a little bit of jam or sugar will do the job. Just make sure you mix baking soda in your bait carefully so that ants cannot sense it while consuming the bait.

Use Essential Oils - 1

Essential oils can work in many ways when ants are on your target. Carpenter ants use pheromone trails for communication with other carpenter ants about the food or when it is safe to come out. You can destroy these pheromone tracks by wiping the floor with essential oil. Once their communication is broken, you can take advantage of the situation.

Use Essential Oils - 2

So, as we mentioned, essential oils could be used to get rid of carpenter ants. One way is to make a solution of essential oil by mixing it with water. You can take any tangy essential oil for this purpose, such as lemon, tangerine, or other citrus-based oil. Once the solution is ready, load it into a spray and directly spray it on the nest. But for that, you need to find their nest. And that can be easily done by using a bait (without any killing agent) and then tracing the carpenter ants going back to their nest with the bait.

Use Vinegar

What is better than using a table condiment to get rid of those annoying critters? You just need to mix some vinegar with water to make another non-toxic ant-killing spray. Use equal amounts of both water and vinegar for the effective working of the solution. Once the solution is ready and you know where the nest is located, no one can stop you from getting rid of the carpenter ants.

Use Professional Help

You can resort to this step if you cannot find the nest of carpenter ants in the first place. Or if you just want to keep away from getting into a killing spree. Professional pest controllers can be contacted from anywhere in Canada. In some cases, you can even get the same-day service.

Conclusion

If you are not sure about the intensity of the infestation that is going on in your home, then it is better to contact professional pest controllers as a first step. Even if you can track the nest of carpenter ants and destroy the nest, you never know if there are more than one nests. And if you are on a complete DIY mission, then the tips mentioned above will come in handy for you.
