Smidge definitely works i've put that stuff through some serious testing, it needs reapplication every couple of hours for full effect and more often if you're a heavy sweater when active but that's expected, i came back last time without a single bite, my bro was not so lucky as he fell for the oldest midge trick in the book and got the top of his butt and lower back savaged as he never tucked himself in and everytime he bent over collecting wood and stuff they feasted on the bare flesh, everywhere else he had applied smidge and in the bad times had a beaton jacket on but not tucked in, he said he will not need to learn that lesson again the hard way.
