Yeh, use smoke...It makes a world of difference!
My bees all used to be calm and never stung me.....But, I have a dog now who runs thru the apiary chasing anything his eyes see or thinks they see, resulting in bees that sting me.
However......I'm not the conventional type of beekeeper...I'm in my 3rd year...I hardly ever suit up...I'll take the stings over roasting alive in the beesuit any day! This doesnt mean I like stings by any means
...But, this year, I try to use my smoker more often, even when feeding...Like Iddee says, the smoker also moves bees out of the way so you dont mash as many when putting stuff back together. I dont like having to light my smoker as it seems to just start working good after Ive done what I needed to do! It always takes me awhile to get it lit too. I probably should use a propane torch to start it.
I dont know what the bees are doing outside in the evening but I sometimes have bees working my moonflowers way after the sun goes down(but not all dark yet).
