I've seen some beetles around in my garage and in the house. Does that mean that I could have a problem with grubs? I don't have the symptoms of grubs yet but I hear that they do damage in the fall. Should I put down some sort of preventative insecticide for them and if so, what should I use? FYI I just laid Tall Fescue Sod about 6 weeks ago. A little brown patch but other than that it looks fine. I'm in Atlanta, and we're getting a lot of rain. I put down a fugicide about a two weeks ago.
