Any lawn pro's with some advice?

So, any of you gurus got tips to get rid of nightcrawlers? They are overrunning my yard, and making it very un-grandkid friendly. My first and only turns 11 months in a week, and will soon be walking, and spring is nearly upon us.I think Id be willing to spend some project money on it. I got a second one on the way, who will be walking, maybe as early as late next summer.
BTW, those little critters were accidentally released about 400 ft north of me in the 80s and are working their way south. Over the past 3 decades they are now nearly 800 ft south of me.Everybodys got these lumpy,crappy,golf-ball infested lawns.After a heavy rain it doesnt take long for my lawn to turn red....from the feasting Robins.
I would be so happy to be rid of them.
Sorry to barge in on your thread.
