Yellow jackets are more plentiful this year here in southern Indiana. Just killed a nest right outside my back door. Aggressive little beasts. Bald face hornets seem to be thriving also. Had an infestation of European hornets (my son in law calls them mega yellow jackets) in a bathroom vent. They were tough to eliminate. Taken down several red wasp nest so far this year. That being said, the carpenter bees were not too bad this year.
