The first thing to consider when trying to figure out how to get rid of carpenter ants is to determine that they are in fact carpenter ants. One way to do this is to find pictures of carpenter ants and compare them to your invaders.
Carpenter ants are unusually large and black-ish in color. Some female carpenter ants have wings and are commonly mistaken for termites. Another way to determine that you have carpenter ants is to analyze their characteristics, habits and dwelling locations. Carpenter ants are generally nocturnal, meaning most of their activity occurs at night.
By activity, we mean coming out of the nest to look for food. They usually build their nests in soft, rotted or rotting wood. They prefer moist conditions. This could include any type of wood, inside or outside.
Once you’ve determined that you do have carpenter ants, you now need to kill them. Carpenter ants differ from other ant species in that they seem to be smarter and more resilient. Placing ant bait traps and hoping that the worker ants will bring poison back to the nest might work, but with carpenter ants you probably want to find the nest and destroy it just to be sure. It can’t hurt to do both.
Find the nest and destroy it and then place ant bait traps just in case there were survivors from possible satellite colonies or ants who weren’t in the nest at the time.

How To Find Carpenter Ants Nest
Remember that carpenter ants are nocturnal, so this will need to be done late at night. Place some non-poisoned bait (syrup or honey) near where you’ve spotted the ants. Then follow them. Don’t kill these ants. If one finds the bait it will leave a scent trail so others can find it as well. Watch for more ants and simply follow their path. Look for cracks, crevices or holes that they disappear into. Their nest is likely behind the wall somewhere nearby where they enter.
If it appears that they are going back outside, this may be where the nest is located. Look for soft or rotten wood outside near where the ants appear to be entering and exiting the house. Just because you see them inside, doesn’t necessarily mean that their nest is inside.
How To Kill Carpenter Ants
If the nest is outside and easily accessible, simply pour boiling water into the nest. After you do that, it wouldn’t hurt to spray it down with some sort of ant killer product. Just to be sure, place ant bait traps around the area after you destroy the nest. If the nest is inside and not easily accessible (like behind a wall), you may need to drill holes in the wall in order to spray ant killer into the nest.
If you are certain of the location of the nest, your best bet might be to cut out a section of the wall. By doing this, you will ensure that you spray down every last bit of the nest. Also, you will be able to check for damaged wood that may need to be replaced.
Again, it wouldn’t hurt to place ant bait traps in the area after the nest is destroyed.
