ELI5:  Why do bees become less aggressive/fall asleep when beekeepers pour smoke into their hives?
gpt
Bees communicate using chemicals called pheromones. The smoke blocks the pheromones so communications between bees are essentially cut. While it does calm the bees, it can also set hive production back a day or two until the smoke wears off and communications are restored. For this reason, some beekeepers prefer to spray their bees with sugar water. It keeps the bees busy licking it off one another and since it is a food source, hive production isn't interrupted very much.
