No quick fix that I know of I'm afraid. I'm also plagued with it. Fortunately, it's a fairly shallow rooted little beast, with easily identifiable foliage, so vigilance and ruthlessness may be the only way to go. Once they've flowered, their seeds shoot off like projectiles, so there's another few generations of it, so if you can get it before flowering, that's a bonus. I never put it on my compost heap either.
