Mosquito-repelling plants can be effective in deterring mosquitoes, but their efficacy may vary compared to traditional repellents. While some studies suggest that the oils from certain plants like citronella, basil, lemon balm, peppermint, lavender, and catnip have mosquito-repelling properties, they may not offer the same level of protection as commercial insect repellents containing DEET or picaridin. However, using a combination of both natural plants and traditional repellents can enhance overall protection against mosquitoes.
