There were a lot of ants going in and out of the hives yesterday especially the one I was trying to salvage from a dead out. I spread cinnamon all around the hives then I went out and purchased DE. I spread the DE on the two closest ant mounds. This morning there were no ants at the hives but there were ants on the mounds walking through the DE. Hopefully over several days the ant numbers will decrease and if it works I'm buying industrial size bags and putting DE around all the mounds.
