The bee problem seems to be resolved! It was the new feed type I had been using.
After hosing out the bucket, I put more feed in and the bees came right back. Then I hosed out the bucket again and instead put their prior food in it. The bees were no longer interested.
I did see some bees near my blooming squash plants-- just where I want them to be!
Glad it was a simple solution and I didn't have to resort to bee traps (though thankful for @cavemanrich suggestion and instructions).
Thanks, @BlueBaby for the idea of checking the feed type.
