Invasive weed question 2: What's the best way to get rid of wild roses?

I had a huge one that, after several days of fierce battle with various pruners and saws, I was able to get down to the stump but I never took care of removing the stump. There are smaller ones that have popped up in the same area where the huge wild rose was but I also have little ones growing all over the back section of my backyard, that area, about a 4 foot wide strip, along my neighbor’s rear fence is pretty wild.
