There are several scents that repel mosquitoes, including:

• Citronella: This oil, which comes from the lemongrass plant, is commonly used in commercial bug sprays and candles. It features a lemon-like citrusy scent that is irritating to mosquitoes, but pleasant to people.

• Lavender: This scent is a favorite of many people, but mosquitoes detest it. Lavender candles or essential oils can be used to make your air more pleasant while making it intolerable to these biting pests. You can also try planting some lavender in your garden to keep mosquitoes out of your space.

• Peppermint: This scent is effective at repelling not just mosquitoes but also ants, spiders, and other insects. Peppermint oil can be used in a diffuser or a candle.

• Lemongrass: This scent contains citronella oil, which is perhaps the most famous of mosquito repellent scents. You can plant lemongrass outside your home as an attractive, yet effective repellent. You can also use lemongrass oil on your skin for a quick mosquito repellent.

• Rosemary: This scent is not something mosquitoes are interested in and it will often mask the scent of food. A strong smell of rosemary will likely keep mosquitoes away. You can try crushing up some rosemary leaves in your garden.

• Eucalyptus: This oil is made from the leaves of the eucalyptus tree and has a refreshing scent. It is also used as a decongestant. You can use eucalyptus oil in a diffuser or a candle.

• Cinnamon: This spice can also repel mosquitoes. Its strong, spicy scent can mask the carbon dioxide you emit, making it difficult for mosquitoes to locate you. You can try using cinnamon candles or essential oils.

• Marigolds: These flowers emit insecticides that are toxic to mosquitoes. You can plant marigolds in your garden to keep mosquitoes away.

It is important to note that while these scents can be used to keep mosquitoes at bay, they may not be as effective as chemical insect repellents.
