Here’s a short video of some guard bees patrolling the bottom entrance of a hive.
The bees were recovering from being smoked after I did a newspaper combine that let the new bees in too fast. Some bee battles started up. Instead of watching a few thousand bees go at it (and the queen possibly getting killed in the melee), I hit them with some smoke. In theory, when the smoke clears, all the bees’ pheromones are messed up, nobody knows who anyone is and they become all touchy-feely getting to know each other again, along with the new bees.
Continued in my Touchy-Feely Bees video.
