This comment, https://www.reddit.com/r/science/comments/9immmj/honey_bees_... , explains what I was referring to.
I wasn't directly saying that bees were submerged, just that the amounts they used were far higher than most real-world exposure scenarios.
I know it's sacrilege to try and defend Monsanto, Facebook, or Google on HN for any reason whatsoever, but it would be nice if people didn't go full-on "NaturalNews.com" mode whenever the topic comes up.
