Some smells that mosquitoes hate are citronella, Lavender, Lemongrass, Rosemary, Lemon Balm, Peppermint and Basil.
Mosquitoes also hate the smell of garlic.
You can rub some garlic onto your skin to help keep mosquitoes away from you.
Or make a garlic necklace and wear some garlic around your neck.
I am allergic to the mosquito repellent that you spray on your skin so I cannot use that so I use garlic rubbed on my skin and wear a garlic necklace which has kept mosquitoes away from me.
I also recommend hiring a mosquito exterminator to fog your yard for mosquitoes at least once per month during mosquito season.
After doing that I have had hardly any mosquitoes and I pay $150.00 per month for the mosquito exterminating service which is well worth it to me.
