I faced that demon in three areas and did eradicate it with three treatments of Round Up but before I resorted to chemicals I tried in vain to dig it up to no avail. Just as with Houttuynia, any piece left in the ground will grow and flourish.

Actually, I have only myself to blame for many aggressive plants and Aegopodium is one of them. Back in the 70's when I used to weed for my neighbor, the real PIRL, I asked her if I could have some of it and she replied (with great wisdom):
You may have it but you may not say I gave it to you.

Here's the after and before photos of the exact same area showing Aegopodium before I eliminated it. You can see the lily stalks in the background.
