Getting DEET at a high enough concentration to be effective is difficult as hell, Zero, countem fuckin zero OTC bugsprays offer it higher than 15 percent, and 20-25 percent is where it actually starts to matter. Further, that’s only a deterrent, and I have been in places where the swarm is so thick you kill bunches just by clapping.
We’re not even getting into the midges, which are small enough to breeze through mosquito netting
Oh you sweet summer child.

Insect mesh netting comes in many grades, you can certainly get a fine enough mesh to block any bug that matters.
