Most Common Signs of a Termite Infestation (And What to Do if You Have One)

To tell the difference between damage from a termite vs. a carpenter ant infestation, homeowners will want to examine the wood carefully. Wood galleries created by carpenter ants will be smooth and have an almost sandpaper texture to them. There will also be small holes where carpenter ants have kicked out debris, usually varying in size. Alternatively, termite-damaged wood contains soil and mud debris with more uniform sizes. If you find carpenter ants in your home, they may have been attracted to the food sources they can find in your kitchen.

Why Are Big Black Ants in My House?

If it’s large and established, it can be even tougher to get rid of. There are several things a homeowner can do to fight against carpenter ants, but keep in mind that treating a large colony is a job that’s best left to a professional. Carpenter ants tend to nest outdoors in dead and decaying wood, such as hollow and rotting trees, old stumps, and even firewood. They can also nest in homes and buildings, in enclosed areas where the wood is damp, wet, or decayed. If infestations grow, the carpenter ant colony may expand into sound wood.

Solved! What Does Termite Damage Look Like?

Next, deal with sources of nearby decaying wood outside the home. Chip up any tree stumps and make sure the debris is removed or mulched in an area well away from the home. Firewood piles should be located well away from the house or garage. Trim away any tree branches so they do not touch the exterior walls or roof. Be aware that unless you also correct the sources of moisture causing the damage, carpenter ants are likely to return as soon as new moisture damage begins. And the wood replacement process can quite involved if the damage has seriously weakened load-bearing walls.

Ant Prevention: Spray Ant Entry Points

Carpenter ants cause serious damage to buildings by boring tunnels in wood. Eliminating moisture in your home and standing water in the yard is half the battle. My housemate used to see them regularly emerge from the wood slat ceiling of her bedroom during the summer. She tried fogging the room with cedar oil, spraying the ants with insecticides and sealing gaps. When we removed part of the roof to fix a leak, we were shocked to discover the ants were the cause — they ate through the decking. If you use a general-purpose pesticide to kill ants, be aware that these chemicals can kill helpful insects, such as honeybees and predatory insects, as well as unwanted ants.

Oil extracted from the lemon eucalyptus tree is another natural insect repellent. It contains citronella, which is used in candles to repel mosquitoes and has been shown to repel certain types of ants. It kills ants and other bugs by absorbing the oils in the exoskeletons, which dries them out. However, since it’s an irritant, avoid breathing it in or getting it on your skin. Once you’ve located the carpenter ant nest, you have several options for extermination.

Carpenter ants can also leave long trails and paths on a home’s lawn.

If you've recently been swarmed by ants, you might have heard that cinnamon is a good deterrent, possibly even killing them. We spoke with pest control experts about whether cinnamon can kill ants, how it works to deter them, and other ways you can rid your home of ants naturally. When carpenter ants build nests, they dig out tunnels in wood, weakening it from the inside. A long-term infestation with multiple colonies in a home often means serious structural damage and unsightly cosmetic damage. As soon as you see carpenter ants in your home, follow them. As these ants walk, they lay down scent trails that allow other ants to follow them to and from food sources.

The thorax is where the six legs attach to the body, and the abdomen is where the vital organs are. They also have powerful mandibles that allow them to bite and cut their food into pieces small enough to carry. Wash all plates and cooking utensils immediately after eating. Try sprinkling the freshly brewed coffee grounds on disposable surfaces (such as index cards) and leaving them in areas where ants congregate, such as pet bowls.

How To Get Rid of Carpenter Ants

Fights emerge all the time as the Immigrant Pavement Ant is one of the aggressive ant species in California. Thousands of dead ants can be found on pavements following these fights. However, all Western Carpenter ant colonies found in homes are satellite homes.

Figuring out how ants are entering your home can help you eliminate an ant infestation and prevent a future one. Check your houseplants for swarms of ants, which might indicate nests underneath the soil. Boric acid is a type of poison that can kill certain types of worker ants, according to a 2023 animal study. It’s best to use neem oil around plants, especially where you see aphids or ants. Ants farm aphids (small sap-sucking insects), so poisoning the aphids with neem oil can take care of both types of pests. Pest experts advise setting out a bait for the ant to take back to the nest, so you can actually find the nest just by watching them.

As far as preventative pest control goes, there’s no better tactic than barrier treatments, whether chemical or physical. Barriers help to ensure carpenter ants won’t gain access to your home in the first place by making the area far less hospitable. Ants are social creatures that form colonies with a queen and thousands of worker ants. The worker ants roam outside the nest to retrieve food for the queen and young ants. These worker ants form and follow trails to lead them back to the nest once they discover a food source in your home. Luckily, there are many ways to effectively reduce the potential development of a major ant infestation.
