How to Get Rid of Carpenter Ants in Your House 

Carpenter ants aren’t just unsightly, they can cause terrible structural damage to your home. These large black ants are experts at tunneling through wood and creating nests, which can weaken the foundation of your house over time. If you’re dealing with a carpenter ant infestation, it’s crucial to take necessary measures to get rid of them before they cause serious harm. In this blog post, we’ll provide you with some tips on how to get rid of carpenter ants in your house quickly and effectively.

So, let’s dive in!

1. Locate the nest by drilling holes

Carpenter ant infestations can be tricky to deal with, but locating the nest is a key step in getting rid of these damaging insects. One effective way to find the nest is by drilling holes into the area where you think the ants are nesting.

This way you can get the insecticide dust or spray it directly into the nest. It’s important to remember to be careful when drilling near wiring and piping because carpenter ants are known to travel along these pathways.

2. Use a bulb duster to apply insecticide

When it comes to getting rid of carpenter ants in your home, using a bulb duster to apply insecticide can be a game changer. First, locate the nest by drilling holes and then used a bulb duster to inject an insecticide directly into the ant tunnels.

This method allows the insecticide to reach deeper into the colony, ensuring that it reaches all the ants and the queen. It’s important to use a pyrethrin-based insecticide or another effective product, like Ficam, for total control. And don’t forget to repeat the treatment if necessary. With a little diligence and the right tools, controlling carpenter ant populations isn’t as daunting as it seems.

3. Bait with ant gel or sweet substance laced with borax (boric acid)

When it comes to getting rid of carpenter ants in your house, using bait can be an effective method. At Identify Pest Control, we prefer using a sweet substance laced with borax or an ant gel to attract the ants. The borax acts as an insecticide and eventually kills the ants.

Place the bait near where you suspect the nest is located, usually near the holes you drilled to locate it. As with any pest control method, diligence is key. Make sure to replace the bait regularly and monitor the ant activity. Using bait is just one part of a comprehensive approach to controlling carpenter ant populations in your home. 

4. Spray foam or gel bait into voids and ant tunnels

The next step in getting rid of carpenter ants in your house is to spray foam or gel bait into voids and ant tunnels. This will help to further infiltrate the colony and eventually exterminate it. Use a non-repellent ant spray. It may take a few days to start killing off the ants but it will spread through the colony and kill more ants.

5. Dust material treatments can flush out hidden nests

Dust treatments can be particularly effective for killing off carpenter ants as well. This involves using insecticidal dust in the hidden nest locations and voids where the ants are located. This technique is particularly important for finding and removing hidden nests that may be difficult to locate with other means. However, precision is key when using this method.

Dusting material should be applied directly into the void or nesting area, and safety precautions should be taken to prevent inhalation. By using dust treatments in combination with other techniques, such as locating and destroying the nest, baiting, and spraying, you can effectively control carpenter ant populations in our homes.

6. Use carpenter ant bait products or aerosol

I’ve found that using carpenter ant bait products or aerosol is an effective way to get rid of these pesky insects. The worker ants take the bait back to the central nest, which can effectively rid the colony. I also recommend using dust to apply into void areas, such as D Fense dust, or aerosols like Fipro Foaming Aerosol, to target cracks and crevices where these ants may be hiding.

Remember, non-repellent ant sprays may take a few days to work, but they do spread through the colony and infect more ants. For a natural option, you could mix equal parts baking soda and powdered sugar and strategically place the mixture in common areas where ants travel. Diligently addressing carpenter ant populations can greatly decrease their presence in your home.

7. Mix water and dish soap in an empty spray bottle

One of the simplest and most effective solutions to eliminating carpenter ants naturally is mixing water and natural dish soap in an empty spray bottle. Just one part soap to two parts water does the trick. This mixture suffocates the ants, making it a natural and non-toxic way to eliminate them.

Plus, it’s easy to use – just spray directly onto the ants or any areas where you’ve spotted them. For added effectiveness, erase the ant trails as well by mixing vinegar and water in a 3:1 ratio and spraying it onto surfaces. It disrupts their scent trails and deters them from coming back.

8. Use vinegar to disrupt pheromone trails

Another helpful method to get rid of carpenter ants in your home is by using vinegar to disrupt their pheromone trails. These trails guide ants toward food sources and their nest. By spraying vinegar around the areas where you suspect ants might be entering your home, you can disrupt these trails and confuse ants, making it harder for them to find their way back to the carpenter ant nest.

Vinegar is a non-toxic and affordable way to keep ants at bay. In addition to using vinegar, it’s important to regularly inspect your home for any signs of infestation and take proactive measures to prevent them from entering in the first place.

9. Hire a pest control professional for effective treatments

While there are several DIY methods to get rid of carpenter ants in your home, sometimes calling in a pest control professional is the most effective option. Experts not only have access to stronger insecticides, but they also have the training and experience to locate nests that may be difficult to find.

Experts can also inspect your property if there are any tree stumps that are infested or other wood on your property that may have carpenter ants in it. It’s also a good idea to trim tree branches and other vegetation around your home to help keep the ants away.

10. Diligence is needed in controlling carpenter ant populations.

Even after locating and treating the nest, it’s important to maintain a clean and dry environment to prevent re-infestation. Regular perimeter treatments can also help deter these pests from entering in the first place. Additionally, using bait products, such as ant gel or sweet substances laced with boric acid, can be effective in controlling carpenter ant populations but it requires you to regularly check your home and refill baits. Overall, it’s important to stay vigilant and take proactive measures to keep these destructive pests at bay.
