I doubt if the Bayer product was the cause of no or less bloom on your daylilies. It is a common product for use in the orchid world and it does not effect the blooms on them and they are pickier about blooming than daylilies.

Save the money and use a homemade soap solution to kill aphids or just a strong blast of water to kill them. They are very soft bodied and die easily but you have to repeat weekly to kill the hatchlings.

I agree with Brooke.Last year was sketchy for all of us.I insecticidal soap is the cheaper answer.I am going to start spraying the soap before I see them,once the scapes start.
