Bees and wasps will stay out of the way, trust me. If you have hornets, quite a few of those species attack. Especially someone running a loud machine, a mower, a blower. You will not hurt bees by hedging. Bees only sting if they get trapped between the brim of your hat and your head (ouch) or your armpit. Wasps, the European Wasp with long legs is very docile. It is hornets to be aware about. They actually attack, it is scary! I had an experience with bald faced hornets who were at a temporary feeding of some dead animal. I got up to the top of the bank to put a poster about a dog up and took a breath and seriously; it was like "on the count of three people"! These hornets were already in my hair and under my shirt and I never noticed them. Cartwheeled down the slope ran zig zag quite explosively only to find those hornets were right with me. Ran back to my truck, got in, windows up, my choc lab just watching me with this LOOK as I screamed, smashed, pounded my own head to kill these hornets. Luckily I decided not to go home and crawl under the covers. 47 stingers still pumping were pulled out of my skin. I've since been stung and luckily I've not been sensitized to have to use an epipen.
Unless there is a nest you are threatening, you really should just hedge your hedge. I appreciate your care for bees and wasps! Hornets are usually found in the country and most people never get to know them! Seriously, I was on my horse my dog found a hive in the rocks, my horse was furious, we finally got out of the drive and up the hill when the hornet hanging out in my hair stung me on the top of my head. It was like a sledge hammer! Over and over again. Hornets are the dudes you do not want to mess with. They are transient, luckily.
Make sure, grins, just fyi, that the bottom of your hedge is wider than the top of your hedge. Never straight up and down. Are you using hand shears or a gas powered hedger? Hornets, some species, go nuts with loud equipment. Bees and wasps are docile compared to some species of hornets.
