Carpenter Ants

Carpenter ants appear as predominately large, sturdy black ants, some with a dark tan or mahogany colorations ranging in size from ¼” to ½”.  Carpenter ants play an important ecological role by helping to decompose dead and fallen trees. They become an important economic pest when these ants invade wooden members of manmade structures. Carpenter ants are responsible for millions of dollars of damage every year in the United States.

What Do Carpenter Ants Use To Build Nests?

Wood is not a food source for ants; in fact, after chewing wood to make tunnels in which to live, the carpenter ant regurgitates it as soft fluffy sawdust. This sawdust combined with bits and pieces of insects on which they have fed is known as frass. Frass is carried from the nest and deposited outside. Frass is one sign of carpenter ant damage, however, it is often never found as ants may dispose of frass within a wall void or other inaccessible location. As a colony expands in size, so does the size of its nest. Workers are constantly engaged in cutting galleries in the wood to accommodate the enlarging colony.

Specialized equipment allows for injection of products deep into excavated wood galleries. Great improvements have been made with bait technologies in carpenter ant control. Proper placement of bait products aids greatly in overall control, however, considerable expertise is usually necessary for effective results. Once satellite colonies are eliminated within a structure outside preventative treatments are usually necessary to help deter ants attempting to re-enter from their natural exterior environment.
