I use the Troll Armor set scouting the Plains and it is really not to hard to spot the skeeters.

A bow shot from afar drops them quickly.

I just take my time and try to stay aware of my surroundings.

Personally I find the skeeters only problematic when I am sailing along a coast in the fog and suddenly cross into a Plains zone and then am set upon by these insect kamikazes.

But even then if you can see them soon enough you can counter them.
