Hello, Just A note: I recently bought a 15 lb. bag of Bayer Lawn and Yard granules to use on Cannas, as one of the PBS members said it worked well on leaf rollers. The main chemical, Imidacloprid, is the ingredient used in Advantage Once-A-Month Flea treatment I use on my dog, and is also manufactured by Bayer Healthcare.
