Carpenter Ant Bite: Is It Dangerous?

Carpenter ants are larger than the traditional pavement or sugar ants you find around your home. Does their massive presence mean they can cause more peril to your family? Is a carpenter ant bite dangerous?

Carpenter ants are common in New Jersey year-round and are luckily not toxic. That doesn’t mean their bite can’t pack a powerful punch. You’re probably gonna feel a sharp pinch that results in a mild stinging sensation. So unless you’re allergic, you should be okay if bitten.

While it’s a good thing that their bite is unlikely to be dangerous to you or your pet, the damage these industrious builders can do to the foundation of your home and other structures is a different story. Carpenter ants love to tunnel and nest in wood, so they have the potential to be as destructive as termites. If you don’t find and resolve an infestation of these ants quickly, it can cost you thousands in structural repairs.

Unlike termites, they don’t feed on wood. They only chew on it to burrow and create hollow areas where they can nest. These ants aren’t dangerous to humans or your pets, but they are drawn to the wood in your home. Damaged areas are an especially tempting area for these workhorses.

Places where water damage has occurred in your home are softer and therefore easier for carpenter ants to bite and tunnel through. The same can be said for a tree in your backyard that’s started to rot from damage. They prey on weakened structures—it’s simply easier to chew their way through them.

The carpenter ant can thrive both indoors and out and they like to build their colonies inside wooden structures making your porch or foundational supports perfect for their needs. They do prefer to stay outside and leave you alone, but will go inside your home when they need nourishment. Since they don’t feed on the wood, they still need to find a source of nutrition for their colony. Unfortunately for you, if they find your home provides what they need to feed their brood, they will start the nesting process. A few ants can quickly turn into an infestation due to the rate at which they breed.

The Bug

It’s easy to tell a carpenter ant from other varieties based on size so if you get a glimpse at the insect who bit you, you’ll know quickly if the carpenter ant is your perpetrator. There is some variation in how big they grow. For example: the queens and winged kinds are pretty massive. They can get up to about an inch long while the worker ants are the smallest coming in at ½ an inch or so.

You’ll notice that the coloring of these ants is different from sugar ants—they’re not always a solid black color. They can be shiny and black, but also, you might find them in hues of red, orange, or a combination of red/black. If you examine them closely, you will see that their body structure differs quite a bit from other ants.

Pay attention to the thorax and abdomen areas. There’s one node instead of two. Another difference that you should be able to see if you get close enough, is that the abdomen has tiny hairs on the tip of it which the other ants won’t have. Their thorax area is also distinct because it’s round and uneven.

The Bite

Now the jaw, known as mandibles, of a carpenter ants is distinct. It is large and has a serrated edge similar to a saw which allows them to easily chew through wood. Those powerful mandibles are also the reason a carpenter ant bite, while rare, is painful. Well that, and the fact that they inject formic acid into the bite—intensifying the sting.

Carpenter ant bites are not venomous and typically look more like a mosquito bite than a fire ant bite.
