Best field conditions for horse with allergy to fly bites?

[Moanypony15]

My horses under side is swollen with allergy to fly bites. Just purchased him a sweet itch rug which will hopefully prevent further bites as I don't want them in saddle or girth area.

Now the dilemma -

Is it better to be in a field with trees around the edge for shelter/shade (probably breeding ground for flies?) or a completely open field with electric and no shade or shelter but less chance of flies. Can't put up a shelter in his field.

Do I keep him with 1 other horse for company or on his own to prevent damage to rug?

Thoughts please

Dry windy away from trees close to the sea .that would be ideal.

Thanks for suggestion - can do the windy and not too far from sea but feel really guilty putting him in electric fencing with no shade or company.

avoid ditches,ponds and tell him not to stay near the trough.
