European Paper Wasps Are Widespread

Four, short years ago we announced we were watching the spread of another invasive into the state of Iowa.  The European paper wasp, Polistes dominula, was first reported in the US in 1978 near Boston, but it was slow to gain our attention until this decade.  In August, 2012 we reported it as relatively new to the state.  Now, in July, 2016, it seems to be everywhere and in some areas it is the only wasp seen around the house.
