I've read that bees and wasps are attracted to bright colors which is what I wear when biking. I've been stung by yellow jackets/wasps but not bees, and there are a always lot of bees around my yard. Mosquitoes are more bothersome. I spray the inside of my helmet and head covering lightly with dilute permethrin which repels insects and kills the ones it doesn't repel. It persists in cloth/clothing for several washes and prevents the bugs that get in my head covering balaclava from being bothersome, they always seem to hone in on my ears which is really annoying.In my younger days of frequent and often distance bike riding (maybe 12 - late teens), I never worried about wearing hi vis clothing, but since I have started wearing bright yellow shirts or outer jackets, I have found bees and other insects seem to be attracted to the color while they are out on patrol. I have been stung so many times by bees that get stuck in this clothing, and I can't be the only one.
Swarms are typically calmer.Very docile bees, I could walk right up in a hovering swarm and none bothered me
That is pretty much opposite. When the swarm on the branch (as well as the hovering bees) had the queen the bees were very docile. I could put my hand within an inch of the buzzing mass on the tree limb without any response from the bees and the flying/hovering bees made no response to my presence. I could even walk up to the boxes this morning without a reaction from them. But when the boxes of bees were removed and the queen was taken from bees left behind (and she is definitely gone now) the remaining queenless stragglers (many hundreds) got agitated, as they are now. I'm not a bee expert by any means but that is also what I've read on more than one beekeeper site "The absence of a queen bee affects the behavior of worker bees, making them agitated or aggressive".The swarm is still there because there's a Queen that they are protecting. If you calmly find the Queen and move her, then the swarm will follow. Get a smoker to help calm them down. If you are nervous around them, they can feel it by your electrical impulses firing all crazy around.
I used to have a 2200 tree peach orchard and dealt with bees quite a lot. They are amazing to learn about. Good luck! Please don't poison them.
