We have an ongoing ant problems, which we have been treating.

We have roses in the front of our porch. The rose bed is between the drive, sidewalk, and the porch foundation.

About 7 feet up the drive way I have had to extensively treat the ants that are in a crack between the drive way and the porch foundation.

Could the ant poison be killing the roses if the ant poison ran down the drive way into the rose bed?

One day the rose bushes seem to be thriving covered with blooms. The next day the leaves start turning brown, until over a couple of days the branch and then the bush are dead.

We have been using Amdro and the BASF equivalent for ant treatment.
