How do I treat carpenter ants in trees? Soil drench or spray the tree-using Dominion 2l
trees are already infested and definetly are nested
You should spray topically for ants. Soil drenches using Dominion 2L around the tree will only protect the tree from insects that actually eat parts of the tree which the ants do not (they just remove small pieces to build nest, they do not eat the pieces they remove).
