Today is our swarming day too! We usually get a light swarming day, then a heavy swarming day, in October sometime. Never know when they will hit, but it's usually a day when it's warm and the sun is shining. They get me from the south side mostly. And if they get in, you NEVER get rid of them. My DH has been caulking our light fixtures for years now, and this may be the first year they haven't swarmed into our home. Thank Goodness. I think they got into our attic area and kept coming down thru the fixtures all winter. They drive me nuts.
Never got bit by one though. Oh my! Ours are just really stinky.
