PEPPERMINT is a great mosquito repellent! My daughter was going to TX for a mission trip and was concerned about mosquito bites, since she is allergic to them and they grow to the size of quarters. Plus, she is a mosquito attractant. I sent her with some Peppermint essential oil to try out in repelling the mosquitoes. She said it worked wonderfully! The one time she was bitten was because she had not applied the oil. Her friends were begging for her to share her Peppermint oil with them, and she was worried she would run out before the trip was over. She came home and exclaimed to me "That stuff WORKS!"
