We already have black flies out in the Albany area. Can't wait for the walleye trip to Quebec in four weeks they are going to be plague like again this year. Anyone have any better Black fly repellent other than Deet or a net suite, the two things we use now. I quit smoking, so that isn't going to help any more but we might pick up some cigars on the way up. I can hope for wind, but it never seems to be there to help.
My uncle had one two years ago, he claimed it didn't help any. Have you had them help with black flies or just mosquitoes?
