Can mosquito-repellent grass really repel mosquitoes?
Mosquito-repellent grass refers to Pelargonium citrosum. Under normal circumstances, Pelargonium citrosum has a certain degree of mosquito-repelling effect, although its effectiveness is limited.
The leaves of Pelargonium citrosum contain citronellal, which has some mosquito-repelling properties. Placing Pelargonium citrosum indoors or outdoors, especially when the wind direction is favorable, allows the scent released by the plant to help repel mosquitoes within a certain range. Regularly rubbing the leaves of Pelargonium citrosum can intensify its fragrance and enhance its mosquito-repelling effect. Although Pelargonium citrosum can repel mosquitoes, its effectiveness is influenced by environmental factors. In well-ventilated environments, the scent emitted by Pelargonium citrosum may easily be dispersed by air currents, thus affecting its mosquito-repelling range and effectiveness. Additionally, some mosquitoes may not be sensitive to citronellal, making the mosquito-repelling effect of Pelargonium citrosum less apparent.
It is recommended to use Pelargonium citrosum in combination with other mosquito-repelling methods, such as using mosquito nets, window screens, or applying mosquito-repellent products like insect repellent lotions, to enhance the overall mosquito-repelling effectiveness.
