Big black ants are likely black carpenter ants, one of the largest ant species in North America. These voracious and destructive insects are known to burrow into homes, decayed wood, and other wooden structures to build nests. A professional will know exactly what type of pest has invaded your home, and will be able to tell the extent of the infestation. This information will tell them the right products and techniques to use in treating the pests.
Ant Identification: 10 Common Types of Ants You May Encounter
This species (Brachymyrmex patagonicus) has been introduced to California from South America. However, there’s sufficient evidence to see this species as an emerging household pest. These ants (Camponotus vicinus) are common in Western North America from Canada to Mexico. One of the most important defining elements of Veromessor andrei ants is the capacity to look for food both together and individually. These seed harvesting ants are part of the Veromessor family.
What Attracts Carpenter Ants?
Bait traps are a homeowner’s greatest weapon against carpenters and other species of ants. A pest control professional is often your best line of defense against carpenter ants. A pro can identify these ants, find their hidden nests, and eliminate the pests so they don’t slowly but surely destroy your home. No matter how hard we try, sometimes we can't avoid pesky ants making their way into our homes. They tend to be drawn to rooms like the kitchen, where it's easy for them to find food sources to bring back to the rest of their colony.
How to Know If You Have an Infestation

If you suspect a carpenter ant infestation in your home, the best course of action is to contact a licensed pest control professional. They will conduct a thorough inspection to identify the full extent of the problem. Once the situation is properly identified, the appropriate control measures can be taken. If you’ve been seeing the signs of carpenter ants in your house, you know you have some clean-up to do. Use a shop vacuum to clean up any sawdust, insulation, or wood shavings the ants leave behind.
DIY Methods to Get Rid of Carpenter Ants
Here's how to get rid of ants, including natural ant repellents, ant prevention tips and ant bait and killer spray recommendations. They range in size from one-quarter inch for a worker ant to up to three-quarters of an inch. They are black or red, or sometimes a combination of both colors.

At this point, the carpenter ants may have caused significant damage that needs to be examined by a professional, and an exterminator will need to be called to control the infestation. In spring and early summer, people may spot swarmer carpenter ants in their homes. Anytime from spring through fall, they might see worker ants—the ones without wings.
The Best Way to Get Rid of Ants
“While house and carpenter ants generally form a primary colony outdoors, they’ll sometimes build satellite colonies inside a home to serve as a conduit for resources,” Gangloff-Kaufmann says. “And both species prefer damp areas.” That means showers, windows, and damp spots in the basement need extra attention. If you’re continually finding black carpenter ants in your pantry, cupboards, or fruit bowl, it’s best to eliminate all accessible food and water sources. Now, that doesn’t mean throwing all of your food away, but rather, sealing it in airtight containers to prevent contamination.

Carpenter ants clean their nesting sites, and their galleries are not lined with mud or moist soil as termite galleries typically are. The workers keep their galleries as smooth as sandpapered wood. Carpenter ants love wet and/or moldy wood, so if there is a moisture issue in any part of your home, they'll be attracted to those areas. However, carpenter ants don't always get into your home by chewing their way through wood. They can enter your home through any crack or tiny opening, even if it is high above the ground (carpenter ants will simply use a branch or climb up pipes and wires to get there). Carpenter ants are nocturnal, so set the bait out at night and then wait.
Where are carpenter ants found?

Amanda Rose Newton is a pest specialist and horticulture expert, reviewing pest control and gardening content for The Spruce's Cleaning and Gardening Review Board. Her passion for pest control and sustainable gardening allows her to review plant and pest content for best practices and accuracy. She is a board-certified entomologist and volunteers for USAIDs Farmer to Farmer program. She is a professor of Horticulture, an Education Specialist, and a pest specialist. You may have an infestation if you have seen the ants in your home or building during the late fall, winter, or early spring.
If conditions are right, the male releases a pheromone that stimulates the female to leave her nest. While carpenter ants do have a painful bite that can break the skin, they are generally regarded as harmless. “Carpenter ants are a fairly avoidable problem if people are doing regular maintenance with their house and noticing if there is a problem with the wood,” he says.
"The primary ingredient in cinnamon that might agitate ants is cinnamaldehyde," says Ismael Girard, CEO of Pest Agent. Did you know that there are more than 700 species of ants in the United States? In fact, ants are the number one nuisance pest in the country. Where you live does matter—for example, the black carpenter ant that lives in the Northern U.S. is more likely to make its home indoors than southern species. Fortunately, carpenter ants don’t pose a significant threat to your health, as they don’t spread disease, and while their bites can be painful, they’re not dangerous and they don’t bite often. The professional may also apply sprays using special equipment that creates an ultra-fine mist that penetrates wood more effectively than any method available to homeowners.
If these fail, try using bait traps or commercial repellants. If you notice ant holes near your home, pour boiling water into them. This method will effectively and immediately kill many of the ants inside. Anthills may appear small, but the ant colonies underneath them are vast. Then, there are the large carpenter ants who have picked up the summer job of destroying your home from the inside out.
Homes with moisture issues caused by leaks are prime targets for carpenter ants. The pests will also use tree branches that overhang roofs as a bridge, accessing buildings to find a way inside. Unsealed openings around utility pipes and wires are common entry points. Because carpenter ants build nests in wood, winged carpenter ants are sometimes confused with termites.
Winged ants have two sets of wings, with the front set being longer than the rear set. This variation in wing size helps to distinguish carpenter ants from winged termites, which have two sets of wings that are roughly equal in size. Diatomaceous earth is a natural substance that is made from fossilized diatoms, tiny organisms found in water. Naturally occurring, it's found in underground deposits and kills ants and other pests.
The gallery walls that carpenter ants create are smooth, with a sand-papered appearance. On the march to find a moist, cozy place to burrow and build their nests, carpenter ants munch through dead, wet wood easily, creating tunnels and cavities to lay eggs and grow their colonies. Think you might have a community of carpenter ants in or near your home? Before you panic, here are some facts you should know about these insects as well as some signs of carpenter ants in your house. However, if you’re finding black carpenter ants in large numbers, you may have a larger issue on your hands. These burrows and tunnel systems can significantly weaken the structural integrity of your home, leading to costly treatments and extensive repairs.
Workers and swarmers (winged ants) are the most likely sign homeowners observe. We back up our pest control recommendations with a detailed rating methodology that we use to objectively score each provider. If you see these combined with a relatively large size, you will know you are looking at a carpenter ant. Carpenter ants can bite and have powerful jaws, so their bites can be painful.
