Re: Sometimes one really has to wonder about the subheadings around here.
"The biggest problem facing us were the gazillion, gazillion mossies/sq metre that fill the air anywhere near water in summer."
If they are the same as in Scotland then they are not mosquitoes but midges. It is said in Finland that they get bigger and more voracious the further north you travel. They do disappear in late July though - on a camping trip that welcome effect was very noticeable over only a few days. We saw the last stragglers in the evening camping on Punkaharju - otherwise a paradise for midges.
