There are also many plants that have mosquito repellent effects. Xiao Jiu introduced several common potted mosquito repellent plants.
First, mosquito net vanilla
Mosquito pure vanilla is a new variety cultivated by bioengineering technology. It is an aromatic geranium perennial foliage plant with a new genetic structure. This new species can be said to be an expert in mosquito repellent in the plant world. The citronella gas it emits is not only fragrant and pleasant, but also has the function of purifying harmful gases such as indoor smoke, and is also the nemesis of mosquitoes. The mosquito repellent area of a pot of mosquito net vanilla with a top width of 20~30 cm is 10~20 square meters.
Mosquito net vanilla likes shade, so we put it in the astigmatism part of the balcony for maintenance, and generally use the method of wet and dry when watering.
Second, azaleas.
I heard from many friends that raising azaleas can repel mosquitoes, but azaleas have certain toxicity, so children at home need to pay attention to protection.
We can add a certain proportion of white vinegar when watering, because azaleas like acidic soil.
Third, pyrethrum
The flowers of pyrethrum are of great use. We can soak it in 20 times of water and spray plants, which can effectively prevent many pests. If its flowers are dried in the shade and ground into powder, 50% of pyrethrum powder, 48% of elm bark powder, 1% of naphthol and 1% of colored powder are mixed together, and a certain amount of water is added to make it paste, so as to make mosquito-repellent incense.
When we potted pyrethrum, we should pay attention to loosening the soil once a year in March, April, early July and winter to speed up the generation of pyrethrum.
Fourth, mint.
Mint contains volatile substances such as peppermint oil and menthol, so it can play a small-scale mosquito repellent effect. At the same time, mint has a good air purification effect, and its leaves can also be used for cooling, diminishing inflammation and relieving itching.
Moreover, mint is very easy to raise, as long as a part of river sand is added to the nutrient soil first, mint can be planted After planting, put it in a well-lit place, so that the leaves of mint can grow stronger and darker.
Five, chasing flies and plums
The flowers of Prunus mume are very gorgeous, with three colors: red, yellow and white. Flowers are usually yellow or pink at first, then gradually turn orange or orange in the later period, and finally turn red. Its branches, leaves and flowers will emit a sensitive smell of mosquitoes and flies, which has a strong effect of repelling mosquitoes and flies, and this smell is harmless to people, so it is also known as "turning mosquitoes into flowers".
Nepenthes
Nepenthes is a perennial herb that preys on insects. It has a special organ, where pitcher plants absorb nutrients, that is, its cylindrical insect trap, the lower part of which is slightly larger. It is called Nepenthes because it looks like Nepenthes. Hainan, the origin of China, is also called Leigong pot, which means like a hip flask. We call this kind of plant which can obtain nutrition by catching and digesting small animals such as insects an insect-eating plant.
Nepenthes is a tropical plant, so it is necessary to increase the humidity of its surrounding environment and spray more when maintaining.
Seven, geranium
There are many kinds of geraniums. Geranium is the kind that can repel mosquitoes. It has a unique smell, which makes mosquitoes and flies smell it and run away. It can also be used as essential oil, which can improve the skin.
Pelargonium graveolens is a warm-loving plant, which can not tolerate low temperature in winter, and its suitable growth temperature is between 15-28℃. Drought-tolerant and not wet-tolerant, so we usually water the ground when it is dry, usually once or twice a day in spring and autumn and once a day 1-2 times in summer. And spray water in the morning and evening to increase air humidity.
Eight, wormwood
Wormwood is a kind of plant with special smell, which has good mosquito and insect repellent effect. Moreover, wormwood is irritating, can purify the air, has the function of aromatic resuscitation, can make people clear-headed, improve hearing and memory, and prevent colds.
Igniting wormwood in a safe environment can repel mosquitoes very well. It can also be boiled into warm water and applied to the body to repel mosquitoes; Hanging a dry moxa stick in the shade indoors can also drive away mosquitoes, moths and insects.
Potted wormwood really has too many benefits. Besides the above, it can also be used to soak feet. We cut some wormwood before going to bed, cook it in hot water for a while, and then soak our feet with it (the water temperature for soaking feet should not be too high, just about 40 degrees), and the effect is very good. But children and menstrual women should not use it!
