Any ideas other than pulling them out, does anyone have for getting rid of this you know what this time of year?

Hand pulling would be your best bet this late, unless you have just a tremendous amount of it. Its already gone to seed, so killing it off now would not really accomplish much. You need to kill it before it goes to seed. A couple applications of pre-emergent control next spring and summer will help keep it down.

Thanks John,
What I hate about that is I cant put down grass seed after the pre-emergent is dropped so how can I ever get the thin areas really full?

The best way to go about solving the problem is by seeding now. The cooler temps and fall rains will help the grass establish itself. If you wait too long the bluegrasses in the seed mixture will not germinate, they take 6 weeks. The ryes will take about 6 to 7 days, and the fescues 2 to 3 weeks.

By springtime if you seeded now, you should have an established lawn that you will be able to put down your crab grass preventer on.

Thanks,
I think that is what I am going to do. I am going to spend a day out there with a screwdriver first. Time to put the children to good use.
Thanks

I hate to tell you but your digging the roots out didn't do much more then build up your fore arms crab grass is an annual, each plant dies in the fall, and they come back from seed.
All you have to do is make a scratch on the soils surface in the spring, to enable it to germinate. that is one of the main reasons why I recommend fall over spring seedlings.

Crab is very easy to handpull. No need for any tools. Also, you can overseed now to help fill in the thin areas and apply the pre-emergent in the spring. The grass has more than enough time to get established before first frost. Good luck.

One thing I noticed last year that immediately following the first real frost, the existing crabgrass turned black and is easily pulled. Trouble is that is to late to seed again.
