 natural alternatives for mosquito repellent and one that just doesn't work. The scent and oil this produces has been found to repel mosquitoes and if you do get bitten, the oil can help soothe bites. Not only does this keep mosquitoes away, but it's been found to also kill the eggs. This has been said to be the best at keeping you from getting bit. Not only can you use it topically, but you can throw time leaves into your campfire for extra protection. Although these sound like a good idea, a study found that the sticker had absolutely no effect on keeping mosquitoes away.
