I saw a bunch of holes on the side of our yard, right where the woods meets the lawn (or the burnt out area that should be a lawn) at first I thought they were ant hills but kept seeing wasps or something of that nature go in them.. Now there are many more-this is only one day later,.. I did some research on the internet and think they may be cicadia killer or sand wasps.. anyone have any knowledge of them and how or if I need to get rid of them? They are near DS's basketball hoop .. poor kid,, I don't let him in the backyard because of the fox den,, the side yard now because of this..
