Carpenter ants contribute to the balance of nature by nesting in dead wood and enhancing the decay of it. A carpenter ant colony creates their nest by hollowing out dead wood, such as a fallen log or dead stump. They carve through the wood with their mouthparts, but they don’t actually eat it.
The Carpenter Ant Diet
Carpenter ants mostly eat honeydew, secreted from aphids and scale insects. Their diet may also consist of fruit juice and nectar from flowers. Carpenter ants have been known to eat their own dead, as well as other insects. Carpenter ants look like they consume wood because they use their mouths to carve into it, but in reality they do not eat the wood. They discard it immediately.
