From another aspect, it can be explained whether the mosquito repellent is poisonous or not. At present, the common mosquito-repellent weeds are rue (commonly known as smelly grass), mint, cordate telosma, wampee, fennel, pyrethrum, Jingqiao, five-fingered orange, Eupatorium odoratum, Cinnamomum cassia, geranium and so on. These plants all contain different mosquito repellent ingredients. Flower friends can check if they have mosquito repellent.
They contain mosquito repellent ingredients, mainly some substances called pyrethroids. However, it is impossible and unscientific to drive away mosquitoes in the house only by the pyrethroid odor emitted by one or two pyrethrum mosquito repellent plants.
In addition, mosquito repellent has a special smell, some people will not be used to it, and it is prone to adverse reactions such as headache, nausea and itchy skin. Therefore, when buying mosquito repellent plants, first try whether you can adapt to its smell.
Note: keeping plants with strong smell indoors is harmful to people's health, no matter what plants are the same, don't be obsessed with mosquito repellent. If you keep less, the effect will be minimal. Too much is the same as using mosquito-repellent incense. If there are children at home, it is recommended to use mosquito nets.
