generally speaking, when I am working, I am moving too fast to notice them making me a target.
I do know for a fact that wasps that nest in bushes hate 2-cycle smoke. I used to have a trimmer that ran on 16 to 1 and if I questions about the bush before I started I'd fill it full of smoke before I started trimming.
if there was a wasp nest they'll take off without being mad.
I did just have a love-sick Cicada trying to mount my Mower.
I couldn't figure it out at first. Was landing on the running mower. Didn't pay much attention to it. Then when I goy my trimmer out, he tried to land on it. Sounds a bit more like a Cicada than the mower did. I suppose the engine vibrations are about the same a Cicada sounds.
The trimmer was a bit too close for my comfort. I finally killed him.
