What are flies doing? Why do they want to land on humans?

1.04K views

Summer is here and my area seems to have an excess of flies. I can’t go on a hike without them buzzing all around me and trying to land on me. What do they want?? Sweat? There is plenty of water elsewhere. Can someone explain so I can figure out a way to dispel these demons?

I’m currently at my Dad’s camp in Northern Vermont. I always look forward to this and then I’m reminded when I exit my vehicle at the camp and I’m immediately chased inside by a swarm of Horseflies. They swarm around my head and continuously try to bite me. I drove my truck through the woods and horseflies were absolutely everywhere. Why do we need these things!?!?!?! Is there a bird species I can get to eat them all.
