How to get rid of carpenter ants

Ants are more than just a nuisance. Carpenter ants can cause structural damage, contaminate food and spread disease to humans and pets. One of the most common ants in North America is the carpenter ant (Camponotus pennsylvanicus). Carpenter ants in the house are attracted to moist environments where they can find wood to eat. The most common way for these ants to enter your home is through small cracks in exterior walls, doors or windows. Once inside, nests can be difficult to find and eliminate because carpenter ants do not build their colonies near food sources like other types of ants; rather they build them close to sources of moisture such as bathrooms or sinks where water leaks often occur. In this blog, we will give you some idea of how to get rid of carpenter ants.

How to get rid of carpenter ants

Carpenter ants are of the family of bees and wasps. They belong to the genus Camponotus, which includes more than 1000 species of carpenter ants worldwide. Carpenter ants are named after their habit of nesting in wood, but they do not eat wood as termites do.

The most common type of carpenter ant is called a large black carpenter ant or a bulldog ant because it has large mandibles that look like bulldog’s jaws (hence the name). It can be identified by its shiny black body color, long legs with yellow or orange bands at their joints and a pair of white spots on its thorax (a segment between head and abdomen). Worker carpenter ants are about 5mm long but queen carpenter ants can reach up to 15mm long.

How do carpenter ants get inside a home?

How to get rid of carpenter ants

These ants can enter your home in several ways. They may find their way in through cracks in the foundation, gaps around pipes and window frames, holes in the wall or floor, and holes through the roof. These sneaky critters often choose to enter your house when you’re not looking because they don’t like to be seen. If you notice any of these openings on your property, it’s important to seal them right away so that carpenter ants don’t come inside.

How to get rid of carpenter ants?

To get rid of carpenter ants in the house, use these methods:

  • Vacuum them up. This is the most cost-effective way to kill ants in your home. Simply use your vacuum cleaner with the right attachments to suck up any carpenter ants you see crawling around on the floor or walls. Dispose of them outside and repeat as needed until they’re all gone.
  • Dust them out of their nests with diatomaceous earth (DE). When mixed with oil, DE will kill any insects that come in contact with it by desiccating their exoskeletons and digestive tracts while leaving behind no residue or odor behind when dry again—making it a great option for those concerned about pesticide safety indoors! Apply liberally around areas where you suspect there may be ant activity, but not directly into existing nests or across large areas where children might come into contact; instead just focus on creating an impenetrable barrier between yourself and these pests for maximum effectiveness.

Make a bait to find the nest

The best way to find the nest is to use a bait. To do this, mix water and borax in a container with a lid. Place the bait near where you see ants or think you may have seen them before. You should notice an increase in ants coming out of their nest if you placed it correctly. This can take anywhere from two days to two weeks depending on how long it takes for them to react.

Once there’s an increase in activity around your bait container, follow the ants back inside until they disappear into their nest location.

Eliminate scent trails

Carpenter ants in the house

Carpenter ants in the house are highly attracted to the smell of food, and they can follow these trails back to the source. The only way to eliminate this attraction is by eliminating the trail itself. Remove all dropped food particles from your kitchen after meals, and make sure you sweep your floor regularly. If you have pets or children who spill things during their playtime, be sure that any crumbs get cleaned up as soon as possible; otherwise, ant scouts will find them!

You may also have a problem with other insects in your home—especially if you live near a forest or brushy area where there are plenty of insects for carpenter ants to feed on (and more importantly scurry inside). To prevent these pests from becoming another type of food source for carpenter ants, keep areas like basements clear of dead wood piles and other debris that could attract insects like wasps or termites.

Use Desiccating Dust

  • Use a duster to sprinkle desiccating dust across the floor and walls of your home. This type of powder is non-toxic and will not cause harm to humans or pets if it gets on their skin, nor is it flammable, corrosive, toxic to plants, or harmful to the environment.
  • If you have more than one ant problem in your house, use desiccating dust in every area that has been affected by ants before moving on to another section.

Destroy the nest to kill carpenter ants

You can use a vacuum to remove the ants from your home. However, in order to kill all of them, you need to locate their nest and destroy it.

The best way to find their nests is by observing the ants’ behavior. Carpenter ants often build their nests underground near trees or in wooden structures such as porches and decks. They also like to hide in places where they can get easy access to food sources such as pet food bowls and kitchen cabinets.


Carpenter ants in the house are a common problem in the United States, but they can be dealt with if you know what to do. The biggest thing to remember when dealing with carpenter ants is that they eat wood, so if you have any holes in your home that they might be able to get through then you’ll want to seal them up before starting any kind of treatment process.

As far as treatment goes there are several options available of how to get rid of carpenter ants including baiting and spraying methods but one thing all of these treatments have in common is that they require patience because there’s no way around the fact that killing carpenter ants takes time because their life cycle consists of three stages: egg, larva and adult – this means there will always be some survivors after any given method has been used on an infestation site.
