Fly repellent help / tips needed

[Burgo]

We're at Don Cactus site but it's next to some greenhouses and fly central. Any tips to keep flies away would be welcome. We've sprayed the hedges, burning a mossie coil and tried coins in water so far, but it's like a biblical plague.

here we spray ourselves with repellent. When outside I use cans of fly spray either unperfumed from mercadona or covirans green cheap one & work in a cloud of spray. Then again I am fortnate that it doesn't bother me. If I forget the repellent I use the spray over myself as they bite.
If anything was 100% guaranteed to work there would be no flies.

** In all honesty if they are that bad go somewhere else. You will never get shot of them
