I recently discovered that using Tiger Balm (a muscle rub) on mosquito bite will relieve the itch and burn, it also worked on a couple of spider bites I had. And I also noticed that when I went outside after using it, no more mosquitos came near me. I think it might be the camphor or the menthol in the Tiger Balm. This leads me to wonder if rubbing mint leaves on the skin would be effective. I will test this as soon as I get a chance.
