In summer, there are many mosquitoes. The best way to prevent mosquito bites is to keep mosquitoes from entering. Burning tea leaves is effective in repelling mosquitoes and is non-toxic, while experts remind that mosquito coils are toxic and should be used sparingly. Igniting dried leftover tea leaves as incense will make mosquitoes leave immediately upon smelling it.
A teacher explained that mosquito coils sold on the market contain pesticide ingredients. The function of these pesticides is to kill mosquitoes, not repel them. When mosquito coils are lit, the pesticide components are released into the indoor air. Without proper ventilation, the air indoors retains these pesticide residues. Prolonged inhalation can certainly affect human health, and the elderly, pregnant women, and children should not stay in such environments for long periods. If the purchased mosquito coils are unregulated products, more severe consequences might occur.
When mosquito coils burn, they emit an irritating odor that is particularly harmful to the respiratory tract. Since mosquito coils contain pesticide ingredients, they may also damage the human nervous system. Living under such conditions for extended periods can lead to symptoms like coughing and dizziness, and may even trigger diseases such as asthma.
The reason burning tea leaves is effective in repelling mosquitoes is that the scent released during burning irritates mosquitoes without harming humans. It is known that during the processing steps of green tea, operations often take place late at night in hot weather, yet there are few mosquitoes because the smell from roasting green tea keeps mosquitoes away.
Methods for Repelling Mosquitoes:
1. Place several open containers of cooling oil or essential balm around the room.
2. Hang scallions under the lamp, or put a few scallion sections in a gauze bag. Alternatively, cover the light bulb with orange-red cellophane or silk cloth.
3. Prepare a small spray bottle and several vitamin B1 tablets. Fill the bottle with water, add the vitamin B1, shake well, and spray on all parts of the body before sleep. Oral intake of vitamin B1 can also help repel mosquitoes.
4. Place fresh mint leaves indoors; their unique cool scent keeps mosquitoes away. After being bitten by mosquitoes, rubbing the affected area with clean mint leaves can relieve itching and reduce swelling.
5. A mixture of brown sugar and beer resembles the smell of human sweat. Mix beer and brown sugar into a slurry, pour it into a shallow dish, and place it in a dark corner.
6. Place night-blooming jasmine under the sun during the day and in a cool, upwind location at night. The fragrance of night-blooming jasmine makes mosquitoes flee upon smelling it.
