Wait, that's really surprising to hear. Neem oil can still mess with bees if you spray it when they're active, like during the day. Even if you didn't see it happen, it can mess up their ability to find food or even hurt the larvae back in the hive. I just don't think it's worth the risk when there are safer options, like blasting them off with water or using insecticidal soap. It's one of those things that seems okay until you look closer, you know?
