Unfortunately, there are so many different creatures that can become household pests. And, of course, any type of infestation is extremely stressful and requires a lot of time, effort and money to get rid of. Carpenter ants can become really annoying household pests. How to get rid of carpenter ants without an exterminator? Is that even possible?
Thankfully, you can get rid of the carpenter ants all on your own without any help from the exterminator. The main aim is to find and destroy the ant nest. If you manage to destroy the carpenter ant nest or place a certain chemical there, these ants will disappear. You can use boric acid, the direct dusting method or toxic bait (in case the nest is inaccessible), these are just some of the methods that you can use.
But before trying to get rid of carpenter ants all on your own, you should at least find out how to identify these creatures, right? And once you succeed in getting rid of them, how do you prevent carpenter ants from coming back?

Identifying Carpenter Ants: What Do Carpenter Ants Look Like?
Did you know that there are more than 12.000 species of ant on our planet? Fortunately, only a few of those can become household pests and it’s relatively easy to distinguish whether or not your place is infested by carpenter ants.
These particular ants are usually entirely (or mostly) black and relatively big. To go the extra mile, you can have a closer look at the ant’s body. A carpenter ant has a single node at its waist (between the thorax and the abdomen). A lot of other ants have two nodes (pharaoh ants, little black ants, pavements ants…).
However, there are ants that also have a single node (large yellow ants, crazy ants, odorous house ants…). To ensure that the pest in front of you is a carpenter ant, you would have to take an even closer look at its thorax. Carpenter ants have a thorax that is rounded, while other species of ants have an unevenly shaped thorax.
Do Carpenter Ants Have Wings?
The truth is that at one point in their life practically all ant species will have wings. The insects with the wings are called ‘swarmers’. Basically, those are female and male adults whose main job is to leave their home nest and establish a new one somewhere else.
These winged reproductives can often be spotted on windows, for example. A carpenter ant swarmer will be larger than a regular carpenter ant. After the winged reproductives mate, the male would die and the female would become the queen of the nest.
How Big Are Carpenter Ants
How can you tell if the ant in front of you is a carpenter ant or not? Well, these annoying pests actually are one of the bigger ants. They can be 6-12 mm long (and that’s quite a lot for an ant!).
What Are the Main Differences Between a Carpenter Ant and a Termite?
Of course, you would want to know what insect you are dealing with, an ant or a termite. Fortunately, it is relatively easy to tell the difference. Even though most species of termite produce swarmers that have a black body (just like carpenter ant swarmers), the flying ants are much bigger. A termite with wings will certainly fit onto the face of a dime. Unlike the carpenter ant swarmer.
If you still find it difficult to understand what kind of insect is in front of you, then have a look at the creature’s body. Termites, for example, don’t have a waist (unlike ants). The wings of a termite are white, while the wings of the ant are yellowish. Moreover, termite wings are stacked on top of each other.
If you manage to get really close to the insect, you can have a quick look at the creature’s antennae. If they are straight or have a slight curve – you are looking at a termite. A carpenter ant will have an elbow in its antennae.
What Kills Carpenter Ants?
Carpenter ants can easily infest wooden infrastructure within your house. At one point, it can stop being simply annoying and become dangerous, these insects can develop additional nests and cause a lot of damage to the wood.
The great news is that there are plenty of things that can kill carpenter ants.
Carpenter Ant Bait
Carpenter ants are just like all the other ant species. There are the ‘working’ individuals that are out foraging most of the time. Carpenter ant bait is created to target the insects along their trail (rather than in the actual nest). This is a great option, in case you need to destroy an outdoor colony or if you can’t get close to the nest.
Basically, what will happen is that the ant will pick up the bait and then carry it back home into the nest. As a result, the whole colony will be poisoned.
There are a few important things that you have to take into consideration when choosing the perfect carpenter ant bait. It should be designed specifically for ants to ensure that no other insects ‘steal’ it.
Moreover, the bait should be resistant to various weather conditions, so it doesn’t get destroyed. Don’t put the bait right next to any ant repellents. In such a case, the ants won’t be able to get close to the bait.
Carpenter Ant Insecticides
If you feel like carpenter ant baits are simply not doing the job for you, you can always try insecticides and pesticides. Such a treatment is great for stopping ants from getting inside your house from nearby foliage, debris or trees.
A perimeter treatment will surely stop them from infesting your place. However, make sure to do your research and choose an effective carpenter ant insecticide.
In case you find carpenter ants inside your house, the whole process of getting rid of the creatures will automatically become a bit more complicated. But even in such a case, you can manage to take care of the situation without the help of a professional exterminator.
You would need some time to find the actual nest (or nests). Those are usually located between walls. You can then make drill holes and use aerosol, insecticide dust or foam treatment around the holes.
If you are one of the humans who tries to avoid artificial chemicals, pesticides, and other poisons at any cost, then natural alternatives can be the best solution for you. Boric acid, for example, and diatomaceous earth. The first option will poison the ants, while the soft sedimentary rock will dry the carpenter ants out and shred their bodies.
How to Get Rid of Carpenter Ants – Step-by-Step Instructions
Are you sure that you are dealing with a carpenter ant infestation? If the answer is ‘yes’, then prepare yourself for a long and challenging battle. It is not extremely difficult to get rid of carpenter ants without an exterminator, but you would certainly need some time and patience.
Step 1 – Finding the Ant Nest
First things first, you have to find the nest. There are two types of ant nests – parent and satellite. Of course, the parent nest is the ants’ main home where the queen lives.
However, in case you have a severe infestation, you might also find satellite nests that have emerged simply because there was no longer enough space for more of them in the parent nest.
Bear in mind that if you spot a few carpenter ants running around that does not necessarily mean that the nest is close. You can start from having a closer look at the places where there is constantly moist (the areas around venting entrances and plumbing, around the basement, and so on). Are there any branches hanging close to your house? This can be an entry point as well.
The best way to find the ants’ nest is by following the insects. Of course, this method will take some time. You can use a wide range of food as bait. Wait for the ant to pick it up and then carry the food back to its nest.
Step 2 – Destroy the Ant Nest
The next step is pretty much straightforward, you need to destroy the ant nest. There are two methods that you can use.
Method 1: Use the Carpenter Ant Bait
The workers would take the bait and carry it to the nest. As the thing is poisonous, it will kill the colony. Always remember that carpenter ant bait needs to be replaced every few days as it can simply spoil and end up not bringing any results. Of course, children and animals should be kept away from this poisonous substance.

Method 2: Direct Attack and Insecticide
You can always attack the actual nest, in case you manage to find it. The chances are high that you would need to drill some holes in the wall, but your house would need some repair procedures after the ant invasion anyway.
Once you have found the nest, you can use a special product to spray all over it.
Ortho Home Defense Max, for example, contains Bifenthrin. You can use the wand to spray the chemical over the nest (moreover, the thing is non-staining and odor-free).
When you are choosing a spray against carpenter ants, make sure to check the main ingredients. The insecticide should contain Bifenthrin, Deltamethrin or Permethrin.
Step 3 – Get Rid of the Ant Pheromone Trails
Finally, you have to erase carpenter ant trails. These insects leave scented trails that other ants follow. So, if you see one single ant running around, the chances are high that soon you will spot more insects. That’s why it is important to get rid of this invisible trail.
Simply water won’t really help. But you can always mix 1 part of vinegar with 3 parts of water and pour the mixture in a spray bottle. Spray the potion wherever you have seen the ants in the past.
Bear in mind that this mixture will not kill the ants. You will still need to use carpenter ant bait or special sprays to get rid of them.
How to Find Carpenter Ant Nest – Tips & Guide
Finding the actual nest is an extremely important step to getting rid of the whole colony of carpenter ants that have infested your house or yard.
It is helpful to know how the activity of ants varies depending on the season. For example, during winter months, you might not notice an infestation even if you have one. There is not enough heat and light for the colony to thrive, so these insects might remain dormant until spring.
If you have noticed some carpenter ants in your house during winter, the chances are high that there is a nest inside your house.
A lot of ants are produced in late summer. The swarmers (winged reproductives) can be spotted during late winter and early spring. Once again, if you see any swarmers inside your house during this period, you can be sure that you have a nest inside the house.
Ant colonies prefer moist areas. This fact should help you locate the actual nest. However, remember that there are two types of nests – parent colonies and satellite colonies. Parent colonies include the queen, worker ants, and her brood.
Outside, the nests can be found in rotting trees, tree stumps and roots, boards and logs, and so on. Unfortunately, the nests can also be located inside the house. Ants would, in most cases, prefer the areas under and around kitchen and bathroom tiles, showers, dishwashers, sinks, and tubs.
Parent colonies need to find a moist area in order to thrive. However, satellite colonies can be found in drier places (hollow doors, wall voids, insulation, etc.).
Carpenter ant nests might be challenging to find. That’s why some experts recommend tapping into wood surfaces. Listen for a hollow sound – that can be an indication of damaged wood.
Moreover, tapping can stress the ants out and they will end up leaving their nest. In such a case, you would certainly see the carpenter ants running around (which means that the nest is somewhere in this area).
Last but not least, you can follow the ant trail. Find the insects that are already carrying food as they are returning to their home. Of course, you might need to spend some time, if you decide to choose this method, but you will certainly end up finding the nest.
How to Prevent Carpenter Ants from Coming Back
Getting rid of carpenter ants is just half of the job. You also want to make sure that these annoying insects do not come back, right? Thankfully, there are a few things that you can do about that (bear in mind that this will take quite some time and effort).
- We already know that carpenter ants love to live in moist (water) areas. So, the first thing that you can do to prevent ant infestation in the future is to correct any moisture problems (get rid of roof and plumbing leaks, for example). The leaks should be dried up inside and outside the house. And don’t forget to replace any water-damaged wood.
- Branches and tree limbs can serve as a ‘bridge’ to your house. If you have any trees growing close to the building, make sure to remove them.
- You will have to spend quite some time on sealing all gaps and cracks on the home’s exterior (pay extra attention to the pipe and other wall penetrations).
- Any wood debris or firewood piles should be located away from the house (or at least make sure that they do not touch the garage or house wall). If you have such a possibility, elevate the firewood off the ground.
- Insulate your windows and doors.
- Remove any clutter from your house and the surrounding territory, so that the insects do not find a shelter there.
Do Carpenter Ants Bite?
Unfortunately, carpenter ants can bite humans. And the worst part is that these bites can be pretty painful. These ants are relatively big and have strong wood-cutting mandibles. So, their bite can potentially break the skin.
However, carpenter ants do not just bite for the sake of it. Unlike bed bugs, for example, the ants don’t need to suck the blood of a human. So, what can make a carpenter ant bite you?
Basically, these ants bite for their defense. If a carpenter ant feels that you are a threat or that you are disturbing or trying to destroy its nest, the chances are high that the creature will bite you.
Taking into consideration that our main aim is to destroy the ant’s nest, you might be bitten at one point or another, in case your house or territory is infested. If you get bitten by a carpenter ant, you will certainly feel it. There will be a severe pinching and burning sensation. The size of the bite mark is equal to the size of a pea. The skin will look raised and there might be a blemish.
Thankfully, the bite is not venomous. The venom contains some poisonous elements, but the concentration is very small, so there won’t be any threat to your health.
The reason why the ant’s bite is so painful is the presence of formic acid. If the human feels prolonged pain or develops an allergic reaction, he or she should certainly take a trip to the doctor.
If a carpenter ant has bitten you, make sure to wash the bite with soap and water. Apply a cold compress for around 5-10 minutes. If you have not gotten any relief, then try applying a special cream for bites. Once the wound is clean, make sure to bandage it to avoid any irritation.
What Do Carpenter Ants Eat?
In case you know exactly what carpenter ants prefer to eat, you will be able to choose the right bait and then use it to track the ants to their nest, for example.
Unlike termites, carpenter ants do not eat wood. They carve galleries and tunnels and then establish nests, but they don’t use the wood as food. These insects prefer their diet to include sources of sugar and protein.
If the carpenter ants live outdoors, they would be more than happy to eat other insects or honeydew secretions. Inside, these creatures are ready to eat any sweet foods (jelly, honey, syrup, sugar…), meats, and even pet food (click here to find out how to get rid of the ants in the pet food).
During spring and summer, carpenter ants prefer to go out foraging for food between sunset and midnight. If you spot only a few ants running around during the daytime that does not mean that you don’t have an infestation. The chances are high that all the other carpenter ants are waiting for night to fall to leave their nest.
Now you know that it is possible to get rid of the carpenter ants without the help of an exterminator. Of course, the whole process would require a lot of your time and effort, but the results are certainly worth it.
As soon as you get rid of carpenter ants, make sure to take the preventative measures mentioned above to ensure that these annoying insects don’t make a comeback. Best of luck!
