[Old School]

I just use the Seven spray. I Get them here or there. They seem to hit different plants each time. The ants farm them. Had them on my Burning Bush, a Yellow flower similar to a Black Eyed Susan, without the black eye, and on a Mr. Lincoln Rose last year. Thankfully not too bad usually although they decimated my Rose of Sharon last year when I didn't realize in time they were there. Still waiting for that plant to come back but sadly I think it will not. Good luck!
