verified this); not sure how effective that is. At least it's not
imidacloprid.

Why, what's wrong with that? The product I ended up buying, "Bayer
Systemic Rose & Flower Care", has that as the active ingredient. I
bought it because of the 8 different stores I visited while searching:

A) It was the only one that gave me 5 pounds for $10 or less (Target)

B) It was the least persistent - says "protects up to 8 weeks". The
other formulations and chemicals said 2 months, or up to 12 months for
1. I didn't want things hanging around that long.
