cycadjungle- I have experience with spraying an outdoor rose with Bayer 3 in 1 insecticide spray. It does work on bees, I saw it happen while I was standing there. I had sprayed in on a climbing rose in a container. I was so upset, but there was nothing I could do at that point, except never use it again on an outdoor plant. Thank goodness I had only used it on the one plant.
It's frustrating when you think you're doing something right, and it goes wrong. The Bayer product works well for the intended use, it should just be labeled as "indoor use only".
