One of the other bridesmaids came to the rescue and had an amazing solution. Deodorant... Now I know you are thinking the same thing I was. Weird or what!?! But it works like a charm. All you need to do is roll a little bit of a stick deodorant on the bug bite, wait a few minutes and BAM! All redness is gone, the bite is visibly smaller and the itchy feeling wasn't there anymore.
So next time you are in a pinch, don't forget to pack a mini travel size deodorant in your purse. It could save you, like it saved me.
