Answer: Sounds like carpenter ants. Carpenter ants nest in moist wood including rotting trees, tree roots, tree stumps, and logs or boards lying on or buried in the ground. They do not eat wood: Carpenter ants damage wood by excavating and creating galleries and tunnels. Eliminating a carpenter ant nests is a difficult and challenging task. While it is possible for homeowners to control carpenter ants, in most cases, control should be performed by an experienced pest control applicator. They have the experience and a wider array of products to more effectively control a carpenter ant problem. Contact your local cooperative extension office for currently available control products and/or a list of pest control operators (look in the phone book under "County" offices). Good luck with your tree!
