Demon WP Insecticide is labeled to be used on lawns, ornamental trees and shrubs and it is labeld to treat ants, but it can leave a white powdery residue behind, and it will only kill the ants that come into direct contact with it. You may wish to use some ant bait in addition, applied around the base of the tree, so that they will consume it and share it with the entire colony.
