Garlic and Lavender plants and scents can repel mosquitoes and keep them away from yourself and the area you're in.
Also the best scent to keep mosquitoes away is Citronella you can make Citronella Candles or even buy them and when the Citronella Candles are lit the scent will repel mosquitoes.
However what you really should do is buy what's called a mosquito magnet that uses propane to attract the mosquitoes and then it sucks them inside the mosquito magnet trap and kills off the infestation of mosquitoes so they won't be able to come back.
