Seeds remain viable for a long, long, long time.
You can treat for years and think, I got it , no need to treat.

Within two years you will probably get some back and if you do not deal with it, it gets worse quickly.

I have dealt with it for decades and I still have not learned my lesson well enough yet.
I still pull it by hand if I really want to deal with it best and then treat the lawn.
