Dale from Kansas City writes
Ferti-lome Tree and Shrub Systemic Insect Drench is not labeled for carpenter ants. Carpenter ant nests in trees are an indication of rotting wood. Such trees should be checked to determine whether the rot has weakened the tree enough that it becomes a hazard.
You can use a product such as Dominion 2L both topically and as a systemic to help get rid of carpenter ants and also aphids which may attract them to the trees. Dominion 2L is a non repellent so does not affect the ants immediately and you will continue to see activity. Non repellents allow the insect to cross the treated areas undetecting the insecticide and then transfer the active ingredient throughout the colony.
Talstar P is another option that can be used for a foliar applciation only to the trunk, nest or cavity where ants are found to include, branches, leaves, foliage and the ground surrounding the base of the tree.
