Hi Donal;
I presume you are refering to Midges? These are the annoying little insects that affect the West coast of Scotland. Having been to the Scottish west coast over the last five years, I haven't noticed any particular invasion of vertically challenged people in the summer. OK jokeing apart. Don't let these little monsters spoil what will be the holiday of a lifetime. The scenary is breath taking and the local people very friendly (and not particullary short). Take plenty of insect repellent candles and cream. You will find that the further north you go, the worse the problem seams to get. we spent five days in the CC site just south of Ullapool two years ago, and this was time the midges were a nightmare. However, if you go a little further south, and I would recomend the site at Bunree just south of Fort William, they only become a problem in the evening.
