Deer fly bites here too!!! Just got back this weekend and everyone is getting bit. It doesn't matter where you are staying. I have been to WDW over 50 times and go in the spring every year. This was the first time we have ever encountered this problem. Even the CMs are being biten, and nothing helps. Yes, the bites go in stages, red, swollen, and itch like crazy, esp. at night. We go back in July and will try to find something to take with us, especially since we'll be at the CR and the bugs seem worse around the water. We played mini-golf and couldn't get out of there fast enough. Love bugs are not a bother and we expected them, but saw very few of them....I would call them smart bugs, because they didn't stay to fight the deer flys. ugh! Still got scars and its' been almost 2 weeks since the bites.
