Yep, I know there are other pollinators- but there are definitely plants that are only pollinated by bees (see "Pollinator impact: 4- essential" on https://en.wikipedia.org/wiki/List_of_crop_plants_pollinated...) and that's why I wrote. my comment that way.

Now you've gone from "are they all dead" to "I have an anecdote and some local people reported all their bees died". I, too have seen local anecdotes about that... and then verified that they weren't true, and areas near me have huge and healthy bee populations.
