We were down there this past weekend. The flies were aggressive and biting. We left the beach because we could not take it. We have been coming to MB for years and never encountered this before. Has anyone else had this problem recently. It seems the only thing that you could do is move your chair down to the water’s edge and sit there. However, with my fair skin, that can only last so long. Does anyone of any other solutions? Do any bug sprays work?
