After finding carpenter ants inside the home, I inspected the exterior of the home and found their trail leading to a tree on the side of the house. I examined closer and found their main nest.
Carpenter ants are about 1/2 to 5/8 inches in size and build their colonies in wet, decaying wood. They don't consume wood, but hollow it out to create a gallery for the colony.
Aside from their large size, an easy way to identify carpenter ants is the build up frass (sawdust) they leave behind when creating a gallery.
I sprayed along the interior baseboards, along the sillplate in the basement, and the exterior perimeter of the home with a residual non-repellent. I also treated around the base of the tree with a granular bait.
The ants will carry either of these product back to their nest and transfer it the other ants in the colony. Shortly after, the carpenter ants are eliminated.
I went out on a service call for a new customer in Tinton Falls, NJ who was having issues with carpenter ants getting into his home.
