I work down at the South end of the Madison Valley bordering a Wilderness Area just up the road from Quake Lake. You may be interested to know there's a Wolverine Survey underway in this part of Montana... kind of cool!
I can deal with mosquitoes, though they're worst in June/July. It's the Horse Fly's and Deer Fly's that are absolutely brutal. Deer Fly season is usually limited to about two weeks at most.
Can't say about clothing saturated with chemicals, but mosquitoes go right through synthetics.
This will be another bad mosquito year in the backcountry due to excellent moisture.
At the end of the day, compared to northern New England, our bugs are pretty tame.
