I remember, how I was once cleaning the perimeter of our property for fencing and while using the motor sythe in the deep vegetation on rocky soil, I felt a hot sting on my thigh, thinking it was a little stone that hit me, but after a second burning hit I looked closer and saw, that I was standing in the middle of a whildly buzzing swarm of wasps. Man, I threw the mashine to the gound and ran for my life.... screaming! HAHAHA. I was so afraight. Took me some time to calm down and build up courage to go back an fetch my motor sythe. Later i found out, that I sythed right over the entrance of a wasp earth nest and of course these guys where very unhappy!
