I was about to reply, no one has yet mentioned the MOZZIES! Giant beggers as I recall, but inland Sweden.We've been to Norway three times in the summer and never had mozzie problems. We only had a problem once, in Sweden, on a damp day when we went walking in a forest. They were nasty blighters, but seemed to prefer Martin to me .
We went fully prepared, and with a mozzie net, all redundant.
