If we are outside in the yard or paddock this time of year We have found wearing orange deters most of them. Been doing it for a couple of years now and it seems quite effective.

They are also attracted to some people more than others. I was in the Whitsundays walking through the bush and there were so many attacking I had to go back. They attacked me constantly but they just buzzed around my partner without landing on her or giving her a single bite. Body lotion or in the blood??
They are attracted to dark blue and probably exhaled carbon dioxide & body sweat the same as for mosquitos. It's only the female mossie that bites or syphons the blood off so maybe the same with the march fly.
