Mosquitoes are not only irritating pests that can ruin outdoor activities. But they also pose health risks by transmitting diseases such as dengue, malaria, and Zika.
While there are numerous mosquito repellents in the market, some individuals prefer natural alternatives that are safe for themselves and the environment. Let’s explore 28 perennial plants that repel mosquitoes.
Do Mosquito-Repellent Plants Really Work?
The effectiveness of mosquito-repellent plants has been a topic of debate. While some people claim positive results, it’s important to understand that these plants may not provide complete protection against mosquitoes.
The scent of compounds emitted by these plants might deter mosquitoes to some extent. But they are unlikely to create a mosquito-free zone on their own.
It’s recommended to combine the use of mosquito-repellent plants with other preventive measures such as using mosquito nets, wearing protective clothing, and eliminating stagnant water sources.
