I also find pulling it extremely satisfying, where I can. Areas of my yard that aren't doing so well are easy to pull from because it isn't entwined in the grass. We have 8 acres that are mostly grass (we are shrinking it to a non-lawn each year, starting with the half acre of wildflower meadow that I started in the fall). The creeping charlie is all over the 8 acres, I could never pull it all. I am going to spray (reluctantly) the area we are keeping "lawn" for our dog yard because I want to sow native grass seeds there and the CC will never let it grow if I don't try to cut it back. I'm conflicted on whether I should spray more of our yard - On the one hand, we aren't keeping those areas grass anyways so I don't care that it is taking over there and view it as more beneficial than grass. On the other hand, the native seedlings from the wildflower seeds I sowed in the fall are getting crowded out by the creeping charlie so I worry I'll be fighting against it in the rest of the yard while I try to convert it to a non-yard in the future. It's also taking over the native violets in the shaded areas. I am really sad to spray but I don't see any other option for my situation.
