If left untreated, the infestation can become severe causing serious structural problems. Even though they do not eat wood like termites, carpenter ant hollow or chew out the wood and make galleries and nests inside. With time, as they excavate the wood, they will create connecting tunnels and end up creating big hollows in the wood and weaken the wood with time. As the ants continue with their activities, it will take a long time to be able to notice the damage on the surface.
The carpenter ants vary in colors. They appear reddish orange to black. They also differ in sizes. For example, the workers measure an average of ¼ to 5/8 inches in length, and they are the ones you will see crawling on the surface. The male carpenter ants are also about the same size as the workers, but you will only see them when they get out their nests to mate with the queen ant. The queen is almost three times larger as compared to the worker and male, nearly one inch in size.
These small ants feed on sugars and proteins such as honey which produced by aphids, jelly, meats, syrup, and honey. They can crawl to your home in search of food at night but only in spring and summer.
The ants do not sting, but they can bite and inflict pain with their jaws. If they bite, they will spray formic acid into your wound which causes an unpleasant burning sensation. The carpenter ants usually have two types nesting place; satellite colonies and parent colonies. They will nest in any wood that is rotting such as trees, firewood, old stumps, etc.
Carpenter ants can find their way in your home and buildings through a damaged or wet wood. They can access a building through cracks in the windows and doors. They will create tunnels through the wood and sometimes if the colony is big, they create their way through a healthy wood.
A fully developed colony of carpenter ants can have almost 10,000 ants, and there will only be around 10% to 15% of ants seen outside the nest most likely foraging for food. However, the ants can travel a distance of almost 100 yards looking for food, so if you happen to see one in your home, it may not necessarily mean you an infestation.
