So tell me, why do they even sell "bee outfits" with all the protective stuff? I would have thought that these bees would be stinging the bejeezus out of you, what with all the shaking and pushing and harassing them off the branch and into the hive ....
Read up on your Kipling ("Dymchurch Flit" for a start) about Hobden's son they call the "Bee Boy" and you'll know why I'm asking!
a beehive will vary in its moods with the weather and conditions. on a warm sunny day with all the old and irritable fielders out working, it will be calm and gentle. then touchy in late afternoon when they're back. if there's a honey flow, they'll ignore you. when the flow stops, they dont want you around.
the last half hour before sunset you can do no wrong. the fielders are fed and in for the night, the hive bees are fanning at the entrance to evaporate the nectar, the guards are relaxed and having a beer, or whatever it is that they do when the day is winding down. that's when you load em on a truck, or run a new queen in the entrance, or pop the lids to do a frame count for the customer, and so on. an hour later, they will murder you if you touch em.
swarms are generally happy, but a dry swarm that's been hanging too long will not appreciate being messed with. i used a bee suit if i was shaking bees for sale, because i would shake out 25 pounds of bees into a screened box, maybe 200 pounds at a time. you're in too much of a hurry doing that to be patient with them, so you suit up. and if i was filling baby nucs to raise queens, i always wore a suit, because i was dipping bees out of a box a quarter-pound at a time with a spam can, under red lights.
and lots of bee work is done at night, when they don't fly and don't like to be bothered. on nice days they're the angels of agriculture. at night or in the rain they turn into cockroaches that sting.
