How about dealing with mosquitoes/flies?
I've talked to people who know what it's like living on the land in Siberia (ie. like the Yukon - permafrost and swamps) and it's a life threatening issue. You can't have any skin exposed so traditional methods of dealing with it involve things like greasing your face and using natural repelants. Again.. doable but very unpleasant and it makes it very difficult to do things in the summer.
