I can't tell you why you suddenly have aphids, never having had them before,
but I can tell you that I always have them and why.

I interplant my Iris with roses which always have aphids, and I have ants 
which people say spread the aphids. I am an organic gardener so don't spray 
with chemicals. I buy ladybugs every year, but by the time ladybugs can 
survive the night time low temperatures the aphids are usually in full swing. 
To combat this I spray in the early morning with dish soap. This helps some, I 
am not sure if it is the dish soap or just the spray knocking the aphids off 
the leaves. I also go out with my gloved hands and scrape them off. But I 
never seem to get them all, but enough to keep them under control.

Good luck getting rid of your aphids and I hope you figure out why you have 
them. Perhaps them came with some new Iris to your garden?
