Swarming bees

This was not an ordinary suburban experience. The dogs were outdoors so I opened the patio door meaning to go out and saw a zillion bees. Promptly closed the patio door and peeked out through the windows. These were honeybees, not yellow jackets and there were a bunch of them, just flying around, didn't appear upset but I don't know that much about bee psychology.
Thank goodness for the internet, I looked up the phenomenon and it appears that there is little danger. I gently escorted a couple bees out that had gotten in, and by then I suppose the were swarming elsewhere because I only saw about 30 on the porch flying around.
I think they are looking for a home but hopefully it won't be on my porch because I don't want any turf wars. They are welcome in my garden though.

A small but steady number are entering my home by crawling through the space between the patio doors. I'm hoping that this will not become similar to an Alfred Hitchcock movie
