From what I'm gathering from various travel blogs and chatter here, the little black flies in Iceland are a worsening problem-- some of them bite, some of them don't, all of them are annoying. I'm sensitive to bug bites and will be carrying bug spray in my bag... should I invest in head netting as well? Any other tips for dealing with the flies or recommendations? We're stopping in Akureyri, Isafjordur, Grundarfjordur, and Reykjavik between July 29-August 1, which seems to be the peak of bug season.
