I read from the links provided that oil of lemon eucalyptus is almost as effective at repelling mosquitoes as DEET. I wonder if the tree itself planted strategically (especially for ponds used for aquaculture) could control mosquitoes.
"Oil of lemon eucalyptus [active ingredient: p-menthane 3,8-diol (PMD)], a plant- based repellent, is also registered with EPA. In two recent scientific publications, when oil of lemon eucalyptus was tested against mosquitoes found in the US it provided protection similar to repellents with low concentrations of DEET."
I had absolutely no luck with oil of lemon eucalyptus. While it smells wonderful, and I've grown the plant as an annual many, many summers just because I enjoy having it around, I tried using it as a mosquito repellent and frankly, I think it attracted more of them.
Some things work for some people and not for others. It may just depend on your body chemistry and also on the species of mosquitoes in your area and at that point in the season.
I know for me, DEET is the only thing that truly works.
