Introduction
The unique scent emitted by mint is key to its mosquito-repelling properties. The leaves contain volatile substances such as menthol and mint ketone, which have a certain repellent effect on mosquitoes. When mint plants are growing or their leaves are crushed, scent molecules quickly spread into the air. Mosquitoes' olfactory receptors are highly sensitive to these odors, causing them to actively avoid the area upon detection, thereby creating a protective zone within a certain range.

Generally speaking, mint can help repel mosquitoes. Detailed analysis is as follows:

The volatile substances contained in mint leaves, such as menthol and methyl ketones, have a certain mosquito-repelling effect. When mint plants are growing or when the leaves are crushed, these odor molecules quickly diffuse into the air. Mosquitoes' olfactory receptors are sensitive to these smells, causing them to actively avoid the scent, thereby creating a protective area within a certain range.

Whether mint is planted outdoors to form a natural barrier or crushed and applied to the skin surface, it can exert mosquito-repelling effects. Planting mint in courtyards or on balconies can reduce mosquitoes near living spaces; crushing mint leaves and applying them to exposed skin not only provides a cool sensation that soothes the skin, but the emitted odor can also temporarily prevent mosquito bites, making it especially suitable for outdoor activities.

When using mint to repel mosquitoes, care should be taken to avoid excessive contact. People with sensitive skin may experience allergic reactions after applying mint juice. If skin redness and itching occur, wash off immediately and discontinue use. For large-area mosquito protection, it is recommended to use mint in combination with other methods.
