As mentioned SMIDGE is a great product. I live in a forest, water close by, it gets humid and warm in summer, we have midges but use smidge and find it’s effective. Long past worrying about the wee buggers. Been all over Scotland in all seasons and not once do we even consider destinations depending on a midge count.
Accept that they will be there, end of.
Park up some where you get a light breeze, stay away from standing water and pray for glorious hot sunny weather, that keeps em away.
Just don’t be put off, or restricting areas you go because of a midge or 3 lol
