When I was a kid in the Western Highlands of Scotland I worked on the roads during the summer before going to university. I helped out as a general labourer and brickies mate. The brick layer I helped used to laugh at me as I suffered under the midges. I asked him how he coped with them and he drew out a tub of cream from his pocket. Inside the tub was a cream made with concentrated eucalyptus oil which he swore was his solution to midges. He may have been right but given the amount of it he used I wouldn't have fancied his chances if there were any lost Koalas out roaming the hills.
