It's been raining quite a bit lately, and my lawn is now full of these guys... I've read that there isn't really much you can do to get rid of them without also harming the grass. Is that really the case? Anything I can do to get rid of this nuisance? I have also read that they tend to appear if you have thatch. I mulch when I mow (once a week), yet still, it looks like I do have some thatch going on there.
