Plant Expert from Monroe Advises on Best Plants to Deter Mosquitoes

Mosquitoes are a big problem for many this year, nonetheless in the Monroe area. With this being the peak season for the potential for West Nile Virus, carried by mosquitoes, the high concentration of mosquitoes is particularly troubling. Resident plant expert, Melissa Allman, said there are ways to deter mosquitoes in your landscaping and gardening projects.

"Believe it or not, there are a handful (of natural plants that can be used)," Allman said. "Most can be crushed to get the sap and then applied to the skin, but just check to see if you get any allergic reaction."

Allman said there are also plants that can be grown that will discourage mosquitoes from spending too much time in your yard.

"Citronella Grass (Cymbopogon nardus) is the most popular. Its oil, citronella oil, is the ingredient in most natural insect repellents, but we can't grow it year round in Georgia," Allman said, adding a list of other plants that have the same effect. 

• Catnip (Nepeta cataria) 
• Peppermint (Mentha piperita)
• Rosemary (Rosmarinus officinalis)
• Marigolds (Tagetes spp.)
• Lemon balm (Melissa officinalis)
• Garlic (Allium sativum)
• Clove (Syzygium aromaticum)
• Eucalyptus (Eucalyptus spp.)
• Tea tree (Melaleuca alternifolia)
• Lavendar (Lavandula angustifolia ) 

"There is the Geranium called Citronella plant as well," Allman said. "And last but not least, the old standby.. Cedar tree sap.. Just crush the 'leaves.' Except for the Lemonbalm, catnip, any of the mints (which will get aggressive and out of hand), Eucalyptus tree if you can find it.. Garlic, Rosemary and Lavendar. These can all be grown year round here."
